+
+Each plugin must return an allowed constant for the hook and (usually)
+optionally a "message".

+Plugins are run in the order they are listed in the "plugins"
+configuration.

+
+=item DECLINED
+
+Plugin declined work; proceed as usual.  This return code is always
+allowed unless noted otherwise.

+Qpsmtpd - qmail perl simple mail transfer protocol daemon

+What is Qpsmtpd?
+----------------
 
---
---
--- version 0.10 is a new object oriented version of qpsmtpd.  
---
--- it is meant to be an easily extensibly smtpd engine.
---
---
-
----------------------------------------------------------
-
-Problems:
-  First thing to do is to watch the log carefully.  If it doesn't
-  help you, or even if it does, please post to the maliinglist
-  (subscription instructions above).  qpsmtpd is meant to be a drop-in 
-  replacement for qmail-smtpd, so it should be very easy to get going.
+Qpsmtpd is an extensible smtp engine written in Perl.  No, make that
+easily extensible!  See plugins/quit_fortune for a very useful, er,
+cute example.
 
 
-Configuration files:
-  All configuration files goes into $DIR/config/ or /var/qmail/control/
 
-  qpsmtpd is supposed to support all the files that qmail-smtpd
-  supports and use them in the same way.  When you find that it is not
-  the case, feel free to send a patch to the mailinglist or to
-  ask@develooper.com.
+What's new in version 0.10?
+---------------------------
 
-  Extra files you can use to configure qpsmtpd:
+Version 0.10 is all rearchitected, with an object oriented plugin
+infrastructure.  Weeh, that sounds fancy!  Of course it is keeping the
+well tested core code from version 0.0x which have had more than a
+years production usage on many sites.
 
-     rhsbl_zones
+Noteworthy new features includes a SpamAssassin integration plugin,
+more documentation and support for arbitrarily large messages without
+exhausting memory (up to the size of whatever your file system
+supports).
+
+
+Installation
+------------
+
+Make a new user and a directory where you'll install qpsmtpd.  I
+usually use "smtpd" for the user and /home/smtpd/qpsmtpd/ for the
+directory.
+
+Put the files there.  If you install from CVS you can just do
+  cvs -d :pserver:anonymous@cvs.perl.org:/cvs/public co qpsmtpd
+in the /home/smtpd/ dir.
+
+Now edit the file config/IP and put the ip address you want to use for
+qpsmtpd on the first line (or use 0 to bind to all interfaces).
+
+If you use the supervise tools, then you are practically done now!
+Just symlink /home/smtpd/qpsmtpd into your /services (or /var/services
+or /var/svscan or whatever) directory.  Remember to shutdown
+qmail-smtpd if you are replacing it with qpsmtpd.
+
+If you don't use supervise, then you need to run the ./run script in
+some other way when you startup.
+
+
+Configuration
+-------------
+
+Configuration files can go into either /var/qmail/control or into the
+config subdirectory of the qpsmtpd installation.  Configuration should
+be compatible with qmail-smtpd making qpsmtpd a drop-in replacement.
+
+If there is anything missing, then please send a patch (or just
+information about what's missing) to the mailinglist or to
+ask@develooper.com.
  
-        Right hand side blocking lists, one per line. For example:
 
-           dsn.rfc-ignorant.org does not accept bounces - http://www.rfc-ignorant.org/
+Problems
+--------
 
-        See http://www.rfc-ignorant.org/ for more examples.
+First, check the logfile.  As default it goes into log/main/current.
+Qpsmtpd can log a lot of debug information.  You can get more or less
+by adjusting $TRACE_LEVEL in lib/Qpsmtpd.pm (sorry, no easy switch for
+that yet).  Something between 1 and 3 should give you just a little
+bit.  If you set it to 10 or higher you will get lots of information
+in the logs.
+
+If the logfile doesn't give away the problem, then post to the
+mailinglist (subscription instructions above).  If possibly then put
+the logfile on a webserver and include a reference to it in the mail.
 
 
-     dnsbl_zones
+Extra files you can use to configure qpsmtpd:
 
-        Normal ip based dns blocking lists ("RBLs"). For example:
+   plugins
 
-           relays.ordb.org
-	   spamsources.fabel.dk
+      List of plugins, one per line, to be loaded in the order they
+      appear in the file.  Plugins are in the plugins directory (or in
+      a subdirectory of there).
 
 
-     require_resolvable_fromhost
+   rhsbl_zones
+ 
+      Right hand side blocking lists, one per line. For example:
+
+          dsn.rfc-ignorant.org does not accept bounces - http://www.rfc-ignorant.org/

-        If this file contains anything but a 0 on the first line,
-        envelope senders will be checked against DNS. If an A or a MX
-        record can't be found the mail command will return a soft
-        rejection (450).

+  ... everything (?) that qmail-smtpd supports. 
+
+      In my test qpsmtpd installation I have a "config/me" file

 ============
 
+Make config() better abstracted or configured (to allow configuration
+from LDAP etc).
+
+Make queue() better abstracted or configured (to allow LMTP delivery
+instead of using qmail-queue).
+
 Methods to create a bounce message easily; partly so we can accept a
 mail for one user but bounce it right away for another RCPT'er.

Subject: [PATCH 0078/1467]   Reorganize most of Qpsmtpd.pm into
 Qpsmtpd/SMTP.pm.

  Add spool_dir option (thanks to Ross Mueller <ross@visual.com>)

  Add plugin name to the "hooks" data structure, so we can log plugin
  module had an error when we run a hook.

+http_config
+
+=head1 DESCRIPTION
+
+Example config plugin.  Gets configuration data via http requests.
+
+=head1 CONFIG
+
+http_config is configured at plugin loading time via the plugins
+config.  Load the plugin with a list of urls like the folllowing.
+ 
+  http_config http://localhost/~smtpd/config/  http://www.example.com/cgi-bin/qp?config=
+
+Looking to config "me", qpsmtpd will try loading
+http://localhost/~smtpd/config/me and if failing that then try
+http://www.example.com/cgi-bin/qp?config=me
+
+=head1 BUGS
+
+http_config doesn't do any caching.  It should do some simple caching
+to be used in production.

+=head1 NAME
+
+spamassassin
+
+=head1 DESCRIPTION
+
+Plugin that checks if the mail is spam by using the "spamd" daemon
+from the SpamAssassin package.  L<http://www.spamassassin.org>
+
+SpamAssassin 2.40 or newer is required.
+
+=head1 CONFIG
+
+Configured in the plugins file without any parameters, the
+spamassassin plugin will add relevant headers from the spamd
+(X-Spam-Status etc).
+
+The format goes like
+
+  spamassassin  option value  [option value]
+
+Options being those listed below and the values being parameters to
+the options.  Confused yet?  :-)
+
+=over 4
+
+=item reject_threshold [threshold]
+
+Set the threshold over which the plugin will reject the mail.  Some
+mail servers are so useless that they ignore 55x responses not coming
+after RCPT TO, so they might just keep retrying and retrying and
+retrying until the mail expires from their queue. 
+
+I like to configure this with 15 or 20 as the threshold.  
+
+The default is to never reject mail based on the SpamAssassin score.
+
+=item munge_subject_threshold [threshold]
+
+Set the threshold over which we will prefix the subject with
+'***SPAM***'.  A messed up subject is easier to filter on than the
+other headers for many people with not so clever mail clients.  You
+might want to make another plugin that does this on a per user basis.
+
+The default is to never munge the subject based on the SpamAssassin score.
+
+=back
+
+With both options the configuration line will look like the following
+
+ spamasssasin  reject_threshold 18  munge_subject_threshold 8

 Carraway <qpsmtpd-list@devin.com> To: qpsmtpd@perl.org Subject: HELO hook and
 check plugin

Speaking of direct-to-MX spam, both AOL and Yahoo are large companies
with whole walls-full of servers devoted to mail delivery.  None of them
announce themselves with "HELO yahoo.com" or "HELO aol.com."  Spammers
certainly do, though.

Here's a patch to SMTP.pm to add hooks for HELO and EHLO, and a plugin
to use them.

 ======
 
+add whitelist support to the dnsbl plugin (and maybe to the rhsbl
+plugin too).  Preferably both supporting DNS based whitelists and
+filebased (CDB) ones.
+
 Use clamd so we don't have to run with a higher memory limit.  Matt
 has made a Perl module interfacing clamd; the clamav module should use
 that if available.

Subject: [PATCH 0140/1467]   Add not even halfbaked saslauth plugin. 
 Hopefully it'll give us   SMTP AUTH some day.  :-)

  If a plugin running the ehlo hook add something to the ARRAY
  reference $self->transaction->notes('capabilities') then it will be
  added to the EHLO response.

  Add command_counter method to the SMTP object.  Plugins can use this
  to catch (or not) consecutive commands.  In particular useful with
  the unrecognized_command hook.

+Qpsmtpd::Transaction - single SMTP session transaction data
+
+=head1 SYNOPSIS
+
+  foreach my $recip ($transaction->recipients) {
+    print "T", $recip->address, "\0";
+  }
+
+=head1 DESCRIPTION
+
+Qpsmtpd::Transaction maintains a single SMTP session's data, including
+the envelope details and the mail header and body.
+
+The docs below cover using the C<$transaction> object from within plugins
+rather than constructing a C<Qpsmtpd::Transaction> object, because the
+latter is done for you by qpsmtpd.
+
+=head1 API
+
+=head2 add_recipient($recipient)
+
+This adds a new recipient (as in RCPT TO) to the envelope of the mail.
+
+The C<$recipient> is a C<Mail::Address> object. See L<Mail::Address>
+for more details.
+
+=head2 recipients()
+
+This returns a list of the current recipients in the envelope.
+
+Each recipient returned is a C<Mail::Address> object.
+
+=head2 sender( [ ADDRESS ] )
+
+Get or set the sender (MAIL FROM) address in the envelope.
+
+The sender is a C<Mail::Address> object.
+
+=head2 header( [ HEADER ] )
+
+Get or set the header of the email.
+
+The header is a <Mail::Header> object, which gives you access to all
+the individual headers using a simple API. e.g.:
+
+  my $headers = $transaction->header();
+  my $msgid = $headers->get('Message-Id');
+  my $subject = $headers->get('Subject');
+
+=head2 notes( $key [, $value ] )
+
+Get or set a note on the transaction. This is a piece of data that you wish
+to attach to the transaction and read somewhere else. For example you can
+use this to pass data between plugins.
+
+Note though that these notes will be lost on a C<RSET>, so you probably
+want to use the notes field in the C<Qpsmtpd::Connection> object instead.
+
+=head2 add_header_line( $data )
+
+This function appears to be unused. See C<header()> instead.
+
+=head2 body_write( $data )
+
+Write data to the end of the email.
+
+C<$data> can be either a plain scalar, or a reference to a scalar.
+
+=head2 body_size()
+
+Get the current size of the email.
+
+=head2 body_resetpos()
+
+Resets the body filehandle to the start of the file (via C<seek()>).
+
+Use this function before every time you wish to process the entire
+body of the email to ensure that some other plugin has not moved the
+file pointer.
+
+=head2 body_getline()
+
+Returns a single line of data from the body of the email.
+
+=head1 SEE ALSO

+=head1 NAME
+
+milter
+
+=head1 DESCRIPTION
+
+This plugin allows you to attach to milter filters (yes, those written for
+sendmail) as though they were qpsmtpd plugins.
+
+In order to do this you need the C<Net::Milter> module from CPAN.
+
+=head1 CONFIG
+
+It takes two required parameters - a milter name (for logging) and the port
+to connect to on the localhost. This can also contain a hostname if
+the filter is on another machine:
+
+  queue/milter Brightmail 5513
+
+or
+
+  queue/milter Brightmail bmcluster:5513
+
+This plugin has so far only been tested with Brightmail's milter module.

   Added a milter plugin to allow use of sendmail milters
 
+  Don't store the Qpsmtpd object in the Plugin object any more (this
+  caused a circular reference)
+
+  Added a new qpsmtpd-server - a select() based server for qpsmtpd
+
+  Allow a config/relayclients and config/morerelayclients files to
+  define who can relay (useful with the select() server)
+
+  Fixed qpsmtpd unfolding all header lines
+
+  Speed up persistent qpsmtpd's by checking for plugin functions after
+  munging the name (the main breakage was with queue/qmail-queue)
+
+  Use dup2() instead of perl open("<&") style. POSIX seems to work better.

+=head1 NAME
+
+dnsbl - handle DNS BlackList lookups
+
+=head1 DESCRIPTION
+
+Plugin that checks the IP address of the incoming connection against
+a configurable set of RBL services.
+
+=head1 Configuration files
+
+This plugin uses the following configuration files. All of these are optional.
+However, not specifying dnsbl_zones is like not using the plugin at all.
+
+=over 4
+
+=item dnsbl_zones
+
+Normal ip based dns blocking lists ("RBLs") which contain TXT records are
+specified simply as:
+
+  relays.ordb.org
+  spamsources.fabel.dk
+
+To configure RBL services which do not contain TXT records in the DNS,
+but only A records (e.g. the RBL+ at http://www.mail-abuse.org), specify your
+own error message to return in the SMTP conversation after a colon e.g.
+
+  rbl-plus.mail-abuse.org:You are listed at - http://http://www.mail-abuse.org/cgi-bin/lookup?%IP%
+
+The string %IP% will be replaced with the IP address of incoming connection.
+Thus a fully specified file could be:
+
+  sbl-xbl.spamhaus.org
+  list.dsbl.org
+  rbl-plus.mail-abuse.ja.net:Listed by rbl-plus.mail-abuse.ja.net - see <URL:http://www.mail-abuse.org/cgi-bin/lookup?%IP%>
+  relays.ordb.org
+
+=item dnsbl_allow
+
+List of allowed ip addresses that bypass RBL checking. Format is one entry per line,
+with either a full IP address or a truncated IP address with a period at the end.
+For example:
+
+  192.168.1.1
+  172.16.33.
+
+NB the environment variable RBLSMTPD is considered before this file is 
+referenced. See below.
+
+=item dnsbl_rejectmsg
+
+A textual message that is sent to the sender on an RBL failure. The TXT record
+from the RBL list is also sent, but this file can be used to indicate what
+action the sender should take.
+
+For example:
+
+   If you think you have been blocked in error, then please forward
+   this entire error message to your ISP so that they can fix their problems.
+   The next line often contains a URL that can be visited for more information.
+
+=back
+
+=head1 Environment Variables
+
+=head2 RBLSMTPD
+
+The environment variable RBLSMTPD is supported and mimics the behaviour of
+Dan Bernstein's rblsmtpd. The exception to this is the '-' char at the 
+start of RBLSMTPD which is used to force a hard error in Dan's rblsmtpd.
+NB I don't really see the benefit
+of using a soft error for a site in an RBL list. This just complicates
+things as it takes 7 days (or whatever default period) before a user
+gets an error email back. In the meantime they are complaining that their
+emails are being "lost" :(
+
+=over 4
+
+=item RBLSMTPD is set and non-empty
+
+The contents are used as the SMTP conversation error.
+Use this for forcibly blocking sites you don't like
+
+=item RBLSMTPD is set, but empty
+
+In this case no RBL checks are made.
+This can be used for local addresses.
+
+=item RBLSMTPD is not set
+
+All RBL checks will be made.
+This is the setting for remote sites that you want to check against RBL.

+Qpsmtpd::Connection - A single SMTP connection
+
+=head1 SYNOPSIS
+
+  my $rdns = $qp->connection->remote_host;
+  my $ip = $qp->connection->remote_ip;
+
+=head1 DESCRIPTION
+
+This class contains details about an individual SMTP connection. A
+connection lasts the lifetime of a TCP connection to the SMTP server.
+
+See also L<Qpsmtpd::Transaction> which is a class containing details
+about an individual SMTP transaction. A transaction lasts from
+C<MAIL FROM> to the end of the C<DATA> marker, or a C<RSET> command,
+whichever comes first, whereas a connection lasts until the client
+disconnects.
+
+=head1 API
+
+These API docs assume you already have a connection object. See the
+source code if you need to construct one. You can access the connection
+object via the C<Qpsmtpd> object's C<< $qp->connection >> method.
+
+=head2 remote_host( )
+
+The remote host connecting to the server as looked up via reverse dns.
+
+=head2 remote_ip( )
+
+The remote IP address of the connecting host.
+
+=head2 remote_info( )
+
+If your server does an ident lookup on the remote host, this is the
+identity of the remote client.
+
+=head2 hello( )
+
+Either C<"helo"> or C<"ehlo"> depending on how the remote client
+greeted your server.
+
+NOTE: This field is empty during the helo or ehlo hooks, it is only
+set after a successful return from those hooks.
+
+=head2 hello_host( )
+
+The host name specified in the C<HELO> or C<EHLO> command.
+
+NOTE: This field is empty during the helo or ehlo hooks, it is only
+set after a successful return from those hooks.
+
+=head2 notes($key [, $value])

+=head1 NAME
+
+Qpsmtpd::Auth - Authentication framework for qpsmtpd
+
+=head1 DESCRIPTION
+
+Provides support for SMTP AUTH within qpsmtpd transactions, see 
+
+  L<http://www.faqs.org/rfcs/rfc2222.html>
+  L<http://www.faqs.org/rfcs/rfc2554.html>
+
+for more details.
+
+=head1 USAGE
+
+This module is automatically loaded by Qpsmtpd::SMTP only if a plugin
+providing one of the defined L<Auth Hooks> is loaded.  The only
+time this can happen is if the client process employs the EHLO command to
+initiate the SMTP session.  If the client uses HELO, the AUTH command is
+not available and this module isn't even loaded.
+
+=head2 Plugin Design
+
+An authentication plugin can bind to one or more auth hooks or bind to all
+of them at once.  See L<Multiple Hook Behavior> for more details.
+
+All plugins must provide two functions:
+
+=over 4
+
+=item * register()
+
+This is the standard function which is called by qpsmtpd for any plugin 
+listed in config/plugins.  Typically, an auth plugin should register at
+least one hook, like this:
+
+
+  sub register {
+    my ($self, $qp) = @_;
+
+    $self->register_hook("auth", "authfunction");
+  }
+
+where in this case "auth" means this plugin expects to support any of 
+the defined authentication methods.
+
+=item * authfunction()
+
+The plugin must provide an authentication function which is part of
+the register_hook call.  That function will receive the following
+six parameters when called:
+
+=over 4
+
+=item $self
+
+A Qpsmtpd::Plugin object, which can be used, for example, to emit log
+entries or to send responses to the remote SMTP client.
+
+=item $transaction
+
+A Qpsmtpd::Transaction object which can be used to examine information
+about the current SMTP session like the remote IP address.
+
+=item $user
+
+Whatever the remote SMTP client sent to identify the user (may be bare
+name or fully qualified e-mail address).
+
+=item $clearPassword
+
+If the particular authentication method supports unencrypted passwords
+(currently PLAIN and LOGIN), which will be the plaintext password sent
+by the remote SMTP client.
+
+=item $hashPassword
+
+An encrypted form of the remote user's password, using the MD-5 algorithm
+(see also the $ticket parameter).
+
+=item $ticket
+
+This is the cryptographic challenge which was sent to the client as part
+of a CRAM-MD5 transaction.  Since the MD-5 algorithm is one-way, the same
+$ticket value must be used on the backend to compare with the encrypted
+password sent in $hashPassword.
+
+=back
+
+=back
+
+Plugins should perform whatever checking they want and then return one
+of the following values (taken from Qpsmtpd::Constants):
+
+=over 4
+
+=item OK
+
+If the authentication has succeeded, the plugin can return this value and
+all subsequently registered hooks will be skipped.
+
+=item DECLINE
+
+If the authentication has failed, but any additional plugins should be run, 
+this value will be returned.  If none of the registered plugins succeed, the
+overall authentication will fail.
+
+=item DENY
+
+If the authentication has failed, and the plugin wishes this to short circuit
+any further testing, it should return this value.  For example, a plugin could
+register the L<auth-plain> hook and immediately fail any connection which is
+not trusted (i.e. not in the same network).
+
+Another reason to return DENY over DECLINE would be if the user name matched
+an existing account but the password failed to match.  This would make a
+dictionary-based attack much harder to accomplish.  See the example authsql
+plugin for how this might be accomplished
+
+By returning DENY, no further authentication attempts will be made using the
+current method and data.  A remote SMTP client is free to attempt a second
+auth method if the first one fails.
+
+=back
+
+Plugins may also return an optional message with the return code, e.g.
+
+  return (DENY, "If you forgot your password, contact your admin");
+
+and this will be appended to whatever response is sent to the remote SMTP
+client.  There is no guarantee that the end user will see this information,
+though, since some prominent MTA's (produced by M$oft) I<helpfully>
+hide this information under the default configuration.  This message will
+be logged locally, if appropriate based on the configured log level.  If
+you are running multiple auth plugins, it is helpful to include at least
+the plugin name in the returned message (for debugging purposes).
+
+=head1 Auth Hooks
+
+The currently defined authentication methods are:
+
+=over 4
+
+=item * auth-plain
+
+Any plugin which registers an auth-plain hook will engage in a plaintext
+prompted negotiation.  This is the least secure authentication method since
+both the user name and password are visible in plaintext.  Most SMTP clients
+will preferentially chose a more secure method if it is advertised by the
+server.
+
+=item * auth-login
+
+A slightly more secure method where the username and password are Base-64
+encoded before sending.  This is still an insecure method, since it is
+trivial to decode the Base-64 data.  Again, it will not normally be chosen
+by SMTP clients unless a more secure method is not available (or if it fails).
+CURRENTLY NOT SUPPORTED DUE TO LACK OF DOCUMENTATION ON FUNCTIONALITY
+
+=item * auth-cram-md5
+
+A cryptographically secure authentication method which employs a one-way
+hashing function to transmit the secret information without significant
+risk between the client and server.  The server provides a challenge key
+L<$ticket>, which the client uses to encrypt the user's password.
+Then both user name and password are concatenated and Base-64 encoded before
+transmission.
+
+This hook must normally have access to the user's plaintext password,
+since there is no way to extract that information from the transmitted data.
+Since the CRAM-MD5 scheme requires that the server send the challenge
+L<$ticket> before knowing what user is attempting to log in, there is no way
+to use any existing MD5-encrypted password (like is frequently used with MySQL).
+
+=item * auth
+
+A catch-all hook which requires that the plugin support all three preceeding
+authentication methods.  Any plugins registering the auth hook will be run
+only after all other plugins registered for the specific authentication 
+method which was requested.  This allows you to move from more specific
+plugins to more general plugins (e.g. local accounts first vs replicated
+accounts with expensive network access later).
+
+=back
+
+=head2 Multiple Hook Behavior
+
+If more than one hook is registered for a given authentication method, then
+they will be tried in the order that they appear in the config/plugins file
+unless one of the plugins returns DENY, which will immediately cease all
+authentication attempts for this transaction.
+
+In addition, all plugins that are registered for a specific auth hook will
+be tried before any plugins which are registered for the general auth hook.

+=head1 NAME
+
+authsql - Authenticate to vpopmail via MySQL
+
+=head1 DESCRIPTION
+
+This plugin authenticates vpopmail users directly against a standard
+vpopmail MySQL database.  It makes the not-unreasonable assumption that
+both pw_name and pw_domain are lowercase only (qmail doesn't actually care).
+It also requires that vpopmail be built with the recommended 
+'--enable-clear-passwd=y' option, because there is no other way to compare
+the password with CRAM-MD5.
+
+=head1 CONFIGURATION
+
+Decide which authentication methods you are willing to support and uncomment
+the lines in the register() sub.  See the POD for Qspmtpd::Auth for more
+details on the ramifications of supporting various authentication methods.
+Then, change the database information at the top of the authsql() sub so that
+the module can access the database.  This can be a read-only account since 
+the plugin does not update the last accessed time (yet, see below).
+
+The remote user must login with a fully qualified e-mail address (i.e. both
+account name and domain), even if they don't normally need to.  This is 
+because the vpopmail table has a unique index on pw_name/pw_domain, and this
+module requires that only a single record be returned from the database.
+
+=head1 FUTURE DIRECTION
+
+The default MySQL configuration for vpopmail includes a table to log access,
+lastauth, which could conceivably be updated upon sucessful authentication.
+The addition of this feature is left as an exercise for someone who cares. ;)

Subject: [PATCH 0240/1467] move the auth plugins to auth/

rename authsql to auth_vpopmail_sql -- we need a generic "connect to database"
thing with a generic way to configure databases.  ... and then we should have
a more generic "check username with sql" plugin.

+ 
+=head1 NAME
+
+kavscanner - plugin for qpsmtpd which calls the Kasperski anti virus scanner
+
+=head1 DESCRIPTION
+
+Check a mail with the B<kavscanner> and deny if it matches a configured virus
+list.
+
+=head1 VERSION
+
+this is B<kavscanner> version 1.0
+
+=head1 CONFIGURATION
+
+Add (perl-)regexps to the F<kav_deny> configuration file, one per line for the
+virii you want to block, e.g.:
+
+  I-Worm\.Sober\..*
+  I-Worm\.NetSky\..*
+
+NOTE: untested and disabled currently, need volunteers :-)
+
+If this list does not match the virus found in the mail, you may set 
+I<bcc_virusadmin viradm@your.company.com> in the plugin config to send a 
+B<Bcc:> to the given mail address, i.e. the line 
+
+  kavscanner bcc_virusadmin viradm@your.company.com 
+
+in the F<config/plugin> file instead of just
+
+  kavscanner
+
+Set the location of the binary with 
+
+  kavscanner kavscanner_bin /path/to/kavscanner
+
+(default: F</opt/AVP/kavscanner>), NOTE: this may be broken, you want to
+set B<kavscanner_bin> explicitly ;-)
+
+=head1 NOTES
+
+This is a merge of the clam_av plugin for qpsmtpd and qmail-scanner-queue.pl
+L<http://qmail-scanner.sourceforge.net/> with my own improvements ;-)
+Only tested with kavscanner 4.0.x, and bcc_virusadmin untested, as we have no
+use for it currently. I wait for an official change in Qpsmtpd::Transaction
+(reset/set the RCPT TO list) to activate and test the currently disabled 
+B<to_virusadmin> option.

+#!/usr/bin/perl -w
+=head1 NAME
+
+aveclient
+
+=head1 DESCRIPTION
+
+This qpsmtpd plugin uses the aveclient of a kaspersky 5.x server-suite. The original kaspersky
+aveclient is called within this plugin to connect to the local socket of the aveserver. 
+The aveserver runs as a daemon with all virusdefinitions already loaded, what makes scanning veeery
+quick and performant without much load.
+
+When a virus is detected, the mail is blocked and the connection is denied! Further configuration 
+is simple to be added.
+
+=head1 INSTALL AND CONFIG
+
+Place this plugin in the default plugin directory of your qpsmtpd installation. Normaly you can use 
+it with default options (nothing specified):
+
+=over 4
+
+=item B<aveclient>
+
+Optional you may set the path to original aveclient and/or the socket:
+
+=over 4
+
+=item avclient_bin I</path/to/ave/binary>
+
+Set the path to the original aveclient of kaspersky 5.x server-suite.
+Default: /opt/kav/bin/aveclient
+
+=item avdaemon_sock I</path/to/socket>
+
+Set the path to the unix socket of the original aveserver of kaspersky 5.x server-suite.
+Default: /var/run/aveserver
+
+=item blockonerror I<(1|0)>
+
+Whether to block mails on scanning errors or to accept connections.
+Default: 0 (No)
+
+=back
+
+=back
+
+=head1 EXIT CODES OF aveclient (taken from man aveclient)
+
+When launched with the -s option, aveclient returns one of the following codes (if several files to be scanned are indicated  in  the
+command line, the return code corresponds to the results of scanning the last file):
+
+0      no viruses have been detected.
+
+1      unable to connect to aveserver.
+
+2      objects with an unknown viral code have been found.
+
+3      suspicious objects have been found.
+
+4      infected objects have been detected.
+
+5      all infected objects have been disinfected.
+
+6      scan results are unavailable: encrypted or password protected file.
+
+7      system error launching the application (file not found, unable to read the file).
+
+8      scan results are unavailable: file is corrupted or input/output error.
+
+9      some of the required parameters are missing from the command line.
+   
+=head1 VERSION
+
+0.1rc first proof of concept.
+How is load and performance on larger systems? This is tested whith aprox. 900 Clients
+on a small RH-System (AMD, 768 Mhz, 512 MB) MAXCLIENTS set to 40.

The current version of Net::SMTP doesn't make any attempt to determine
the hostname of the current computer (not that I blame Graham for
that), so that all e-mails are sent out as from
"localhost.localdomain" unless an explicit Hello string is provided.

The AV scanner plugin I am currently using (uvscan) requires the
attached patch so that it can scan the existing temp file, rather than
making a copy just for the scan.

+=head1 NAME
+
+clamav -- ClamAV antivirus plugin for qpsmtpd
+
+$Id$
+
+=head1 DESCRIPTION
+
+This plugin scans incoming mail with the clamav A/V scanner, and can at your
+option reject or flag infected messages.
+
+=head1 CONFIGURATION
+
+Arguments to clamav should be specified in the form of name=value pairs,
+separated by whitespace.  For sake of backwards compatibility, a single
+leading argument containing only alphanumerics, -, _, . and slashes will
+be tolerated, and interpreted as the path to clamscan/clamdscan.  All
+new installations should use the name=value form as follows:
+
+=over 4
+
+=item clamscan_path=I<path> (e.g. I<clamscan_path=/usr/bin/clamdscan>)
+
+Path to the clamav commandline scanner.  Using clamdscan is recommended
+for sake of performance.
+
+Mail will be passed to the clamav scanner in Berkeley mbox format (that is,
+with a "From " line).
+
+=item action=E<lt>I<add-header> | I<reject>E<gt> (e.g. I<action=reject>)
+
+Selects an action to take when an inbound message is found to be infected.
+Valid arguments are 'add-header' and 'reject'.  All rejections are hard
+5xx-code rejects; the SMTP error will contain an explanation of the virus
+found in the mail (for example, '552 Virus Found: Worm.SomeFool.P').
+
+The default action is 'add-header'.
+
+=item max_size=I<bytes> (e.g. I<max_size=1048576>)
+
+Specifies the maximum size, in bytes, for mail to be scanned.  Any mail
+exceeding this size will be left alone.  This is recommended, as large mail
+can take an exceedingly long time to scan.  The default is 524288, or 512k.
+
+=item tmp_dir=I<path> (e.g. I<max_size=/tmp>)
+
+Specify an alternate temporary directory.  If not specified, the qpsmtpd
+I<spool_dir> will be used.  If neither is available, I<~/tmp/> will be tried,
+and if that that fails the plugin will gracefully fail.
+
+=back
+
+=head2 CLAMAV CONFIGURATION
+
+At the least, you should have 'ScanMail' supplied in your clamav.conf file.
+It is recommended that you also have sane limits on ArchiveMaxRecursion and
+StreamMaxLength also.
+
+=head1 LICENSE
+
+This plugin is licensed under the same terms as the qpsmtpd package itself.
+Please see the LICENSE file included with qpsmtpd for details.

Subject: [PATCH 0271/1467] Incorporate suggestions and part of a patch from
 Mark Powell: - Make the awkward silence at connection configurable (default
 still 1sec) - Add an option to defer reaction to the HELO to the MAIL-FROM
 command   instead, anticipating broken SMTP agents that don't gracefully
 handle   disconnection after greeting.

Also made the specific response configurable (soft, hard, nothing).

Subject: [PATCH 0287/1467] Fix for hooks not running with previous patch,
 caused by qpsmtpd objects not asking each plugin to register. There is
 slightly more overhead this way, but it feels more correct, and we can fix
 the overhead later in a more clean way.

+=head1 NAME
+
+bounce_verp - verp all your outgoing mail to make bounces work again
+
+=head1 DESCRIPTION
+
+Anyone who has been using mail for a long time will know that bounces from mail
+you didn't send is a real problem. Some solutions have been proposed to handle
+this such as SPF which rely on the rest of the internet to implement SPF
+checking so that they will not send you bounces. This solution works without
+global cooperation.
+
+See also the BATV proposal from Dave Crocker, which uses a slightly different
+syntax.
+
+This module will basically change all your outbound email (those that are considered
+to be B<"relaying">) from the format:
+
+  localpart@domain
+
+Into:
+
+  securehash=ts=localpart@domain
+
+The securehash and ts (timestamp) are short base32 encoded versions of HMAC and epoch
+time respectively. They should be secure enough. The format used is also known as a
+"VERP" or Variable Envelope Return Path.
+
+=head1 ISSUES
+
+There are some problems with verping the return path.
+
+=over 4
+
+=item * Ezmlm - this uses the return path to decide who is sending the mail and thus
+figure out if you are a member of the mailing list.
+
+=item * Qmail - qmail provides very easy access to the return path via the dot-qmail
+files, and so there are likely many systems built on qmail which behave this way.
+
+=item * (Your Entry Here)
+
+=back
+
+Each of these things can be added to the bounce_verp.skip list. (See
+L</bounce_verp.skip> below).
+
+=head1 Configuration
+
+There are a few configuration files you can create. All are optional except for
+F<bounce_verp.secret>.
+
+=head2 bounce_verp.secret
+
+This file is mandatory, and should contain your secrets (no, not those ones).
+
+Each line should contain a secret. The topmost one is used for outbound verping,
+the following lines are used for validation. This allows you to rotate secrets
+should you fear they have been found out.
+
+=head2 bounce_verp.maxage
+
+Default: 7 (days)
+
+The maximum number of days a bounce verp should be valid for. Set this to the
+longest delay you are willing to accept bounces for, on mails you sent.
+
+=head2 bounce_verp.hashlength
+
+Default: 4
+
+The number of characters to store in your email address for your hash. Normally
+four characters is sufficient, however you may wish to increase this if you are
+security concious.
+
+=head2 bounce_verp.hashmin
+
+Default: 4
+
+=head2 bounce_verp.skip
+
+This file should contain a list of email addresses or domains that you should
+skip this verp magic for. The code tries to be a little bit clever to cope with
+systems that send out mails from multiple email addresses, such as ezmlm, so
+that you only have to specify the main address. e.g.:
+
+  foo.com
+  qpsmtpd@perl.org
+
+Will skip verping/checking for all emails to/from any address or subdomain of I<foo.com>,
+and skip verping/checking for all emails to/from the qpsmtpd mailing list, including
+help, unsubscribe, and other sub-list requests.
+
+Note: These addresses are easily forgeable. Patches welcome to add checking of rDNS
+into the mix to eliminate the forgery problem (though rDNS isn't available to everyone).

-=head1 NAME
-
-bounce_verp - verp all your outgoing mail to make bounces work again
-
-=head1 DESCRIPTION
-
-Anyone who has been using mail for a long time will know that bounces from mail
-you didn't send is a real problem. Some solutions have been proposed to handle
-this such as SPF which rely on the rest of the internet to implement SPF
-checking so that they will not send you bounces. This solution works without
-global cooperation.
-
-See also the BATV proposal from Dave Crocker, which uses a slightly different
-syntax.
-
-This module will basically change all your outbound email (those that are considered
-to be B<"relaying">) from the format:
-
-  localpart@domain
-
-Into:
-
-  securehash=ts=localpart@domain
-
-The securehash and ts (timestamp) are short base32 encoded versions of HMAC and epoch
-time respectively. They should be secure enough. The format used is also known as a
-"VERP" or Variable Envelope Return Path.
-
-=head1 ISSUES
-
-There are some problems with verping the return path.
-
-=over 4
-
-=item * Ezmlm - this uses the return path to decide who is sending the mail and thus
-figure out if you are a member of the mailing list.
-
-=item * Qmail - qmail provides very easy access to the return path via the dot-qmail
-files, and so there are likely many systems built on qmail which behave this way.
-
-=item * (Your Entry Here)
-
-=back
-
-Each of these things can be added to the bounce_verp.skip list. (See
-L</bounce_verp.skip> below).
-
-=head1 Configuration
-
-There are a few configuration files you can create. All are optional except for
-F<bounce_verp.secret>.
-
-=head2 bounce_verp.secret
-
-This file is mandatory, and should contain your secrets (no, not those ones).
-
-Each line should contain a secret. The topmost one is used for outbound verping,
-the following lines are used for validation. This allows you to rotate secrets
-should you fear they have been found out.
-
-=head2 bounce_verp.maxage
-
-Default: 7 (days)
-
-The maximum number of days a bounce verp should be valid for. Set this to the
-longest delay you are willing to accept bounces for, on mails you sent.
-
-=head2 bounce_verp.hashlength
-
-Default: 4
-
-The number of characters to store in your email address for your hash. Normally
-four characters is sufficient, however you may wish to increase this if you are
-security concious.
-
-=head2 bounce_verp.hashmin
-
-Default: 4
-
-=head2 bounce_verp.skip
-
-This file should contain a list of email addresses or domains that you should
-skip this verp magic for. The code tries to be a little bit clever to cope with
-systems that send out mails from multiple email addresses, such as ezmlm, so
-that you only have to specify the main address. e.g.:
-
-  foo.com
-  qpsmtpd@perl.org
-
-Will skip verping/checking for all emails to/from any address or subdomain of I<foo.com>,
-and skip verping/checking for all emails to/from the qpsmtpd mailing list, including
-help, unsubscribe, and other sub-list requests.
-
-Note: These addresses are easily forgeable. Patches welcome to add checking of rDNS
-into the mix to eliminate the forgery problem (though rDNS isn't available to everyone).
-
-=head2 bounce_verp.bounce_heuristics
-
-Put a 1 in this file to tell the plugin to use more aggressive heuristics
-in determining whether this email is a bounce or not. The default rules
-for detecting a bounce are:
-
-  MailFrom = <>
-  or MailFrom = <postmaster@domain> 
-  or MailFrom = <mailer-daemon@domain>
-
-Setting C<bounce_verp.bounce_heuristics> makes bounce_verp look in the mail
-headers for various clues too.

 Split check_relay into two plugins

*   config/plugins
    Reorder plugins to take advantage of the new check_relay

*   lib/Qpsmtpd/Connection.pm
    Add support for relay_client() method

*   lib/Qpsmtpd/SMTP.pm
    Copy connection relay settings to transaction object when created

*   lib/Qpsmtpd/Auth.pm
    Use the connection->relay_client() instead of setting an env var

+
+Takes one optional parameter, the number of days in the future or past
+beyond which to reject messages. (The default is to not reject messages

+Apache::Qpsmtpd - a mod_perl-2 connection handler for qpsmtpd
+
+=head1 SYNOPSIS
+
+  Listen 0.0.0.0:25
+  
+  LoadModule perl_module modules/mod_perl.so
+  
+  <Perl>
+  use lib qw( /path/to/qpsmtpd/lib );
+  use Apache::Qpsmtpd;

+  PerlSetVar qpsmtpd.loglevel 4
+  </VirtualHost>
+
+=head1 DESCRIPTION
+
+This module implements a mod_perl/apache 2.0 connection handler
+that turns Apache into an SMTP server using Qpsmtpd.
+
+It also allows you to set single-valued config options (such
+as I<loglevel>, as seen above) using C<PerlSetVar> in F<httpd.conf>.
+
+This module should be considered beta software as it is not yet
+widely tested. However it is currently the fastest way to run
+Qpsmtpd, so if performance is important to you then consider this
+module.
+
+=head1 BUGS
+
+Currently the F<check_early_talker> plugin will not work because it
+relies on being able to do C<select()> on F<STDIN> which does not
+work here. It should be possible with the next release of mod_perl
+to do a C<poll()> on the socket though, so we can hopefully get
+that working in the future.
+
+Other operations that perform directly on the STDIN/STDOUT filehandles
+will not work.
+
+=head1 AUTHOR
+
+Matt Sergeant, <matt@sergeant.org>
+
+Some credit goes to <mock@obscurity.org> for Apache::SMTP which gave
+me the inspiration to do this.

it's a minor thing, but the default port for qpsmtpd-forkserver is 2525
in the code, but it claims to be 25 in the usage text.

also, the $MAXCONNIP was not settable from the command line.

Date: Fri, 28 Jan 2005 03:30:50 +0000
Subject: [PATCH 0343/1467] Changes by jpeacock@cpan.org (John Peacock)

o plugins/check_badmailfromto
    - New plugin in the style of check_badmailfrom, which matches a pair
      of FROM/TO and makes it seem like the recipient's address no longer
      exists (but only from the matching sender's point of view).  Useful
      for stalkers and other harassment cases.

o plugins/dns_whitelist_soft
    - New plugin to provide a DNS-based whitelist (good for distributed
      sites).

o various files
    - Replaced tab character with 8 spaces and adjusted line breaks for
      better readability.

Changes by mct@toren.net (Michael C. Toren)

o lib/Qpsmtpd/SMTP.pm

    - Assumes a MAIL FROM value of "<#@[]>" (utilized by qmail to
      indicate a null sender when generating a doublebounce message)
      is equivalent to "<>".  Previously qpsmtpd complained that the
      value could not be parsed.

    - Adds LOGIN to the default list of supported auth mechanisms.
      The documentation in Auth.pm indicated that auth-login was not
      currently supported due to lack of functionality, however I can
      confirm that LOGIN appears to work fine as tested by using msmtp
      (http://msmtp.sourceforge.net/).  Are there any indications that
      LOGIN support is actually broken in the current implementation?

    - Removes the "X-Qpsmtpd-Auth: True" header appended when a message
      has been sent by an authenticated user.  One problem with such a
      header is that it's impossible to say which SMTP hop added it,
      and it provides no information which could be used to backtrack
      the transaction.  I grepped through my mail archives a bit
      looking for how other MTAs handled the problem, and decided it
      would be best to place this information in the Received: header:

        Received: from remotehost (HELO remotehost) (192.168.42.42)
          (smtp-auth username foo, mechanism cram-md5)
          by mail.netisland.net (qpsmtpd/0.28) with ESMTP; <date>


o lib/Qpsmtpd/Auth.pm:

    - Documentation update for the arguments passed to an auth
      handler; previously the $mechanism argument was not mentioned,
      which threw off the argument offsets.

    - Documentation update for auth-login removing the warning
      that auth-login is not currently supported due to lack of
      functionality.

    - Fix to execute a generic auth hook when a more specific
      auth-$mechanism hook does not exist.  (Previously posted
      to the list last week.)

    - Upon authentication, sets $session->{_auth_user} and
      $session->{_auth_mechanism} so that SMTP.pm can include them
      in the Received: header.


o plugins/queue/qmail-queue

    - Added a timestamp and the qmail-queue qp identifier to the
      "Queued!" 250 message, for compatibility with qmail-smtpd, which
      can be very useful for tracking message delivery from machine to
      machine.  For example, the new 250 message might be:

        250 Queued! 1105927468 qp 3210 <1105927457@netisland.net>

      qmail-smtpd returns:

        250 ok 1106546213 qp 7129

      Additionally, for consistency angle brackets are placed around
      the Message-ID displayed in the 250 if they were missing in the
      message header.


o plugins/check_badmailfrom:

    - Changed the error message from "Mail from $bad not accepted
      here" to "sorry, your envelope sender is in my badmailfrom
      list", for compatibility with qmail-smtpd.  I didn't see any
      reason to share with the sender the value of $bad, especially
      for situations where the sender was rejected resulting from a
      wildcard.


o plugins/check_earlytalker:
o plugins/require_resolvable_fromhost:

    - No longer checks for earlytalkers or resolvable senders if the
      connection note "whitelistclient" is set, which is nice for
      helping backup MX hosts empty their queue faster.


o plugins/count_unrecognized_commands:

    - Return code changed from DENY_DISCONNECT, which isn't valid in
      an unrecognized_command hook, to DENY, which in this context
      drops the connection anyway.  (Previously posted to the list
      last week.)

+  Qpsmtpd::Auth - document $mechanism option, improve fallback to generic
+  hooks, document that auth-login works now, stash auth user and method for
+  later use by Qpsmtpd::SMTP to generate authentication header.
+  (Michael Toren)
+
+  Qpsmtpd::SMTP - "MAIL FROM: <#@[]>" now works like qmail (null sender), 
+  add LOGIN to default auth mechanisms, display auth user and method in
+  Received: line instead of X-Qpsmtpd-Auth header.
+  (Michael Toren)
+
+  check_badmailfromto - NEW PLUGIN - like check_badmailfrom except matches
+  both FROM: and TO:, and effectively makes it seem like the recipient 
+  no longer exists for that sender (great for harassment cases).
+  (John Peacock)
+
+  check_earlytalker and require_resolvable_fromhost - short circuit test if
+  whitelistclient is set. (Michael Toren)
+
+  check_badmailfrom - Do not say why a given message is denied.
+  (Michael Toren)
+
+  dns_whitelist_soft - NEW PLUGIN - dns-based whitelist override for
+  other qpsmtpd plugins.  Add suuport for whitelisthost to dnsbl.
+  (John Peacock)
+
+  auth/auth_vpopmail_sql - Support CRAM-MD5 (requires clear_passwd)
+  (John Peacock)
+
+  plugins/queue/qmail-queue - Added a timestamp and the qmail-queue qp
+  identifier to the "Queued!" message, for compatibility with qmail-smtpd

   Support qmail-smtpd's timeoutsmtpd config file

+check_badmailfromto - checks the badmailfromto config
+
+=head1 DESCRIPTION
+
+Much like the similar check_badmailfrom, this plugin references both the
+FROM: and TO: lines, and if they both are present in the badmailfromto
+config file (a tab delimited list of FROM/TO pairs), then the message is
+blocked as if the recipient (TO) didn't exist.  This is specifically designed
+to not give the impression that the sender is blocked (good for cases of
+harassment).
+
+Based heavily on check_badmailfrom.

+=head1 NAME
+
+dns_whitelist_soft - dns-based whitelist override for other qpsmtpd plugins
+
+=head1 DESCRIPTION
+
+The dns_whitelist_soft plugin allows selected host to be whitelisted as
+exceptions to later plugin processing.  It is strongly based on the original
+dnsbl plugin as well as Gavin Carr's original whitelist_soft plugin.  It is
+most suitable for multisite installations, so that the whitelist is stored
+in one location and available from all.
+
+=head1 CONFIGURATION
+
+To enable the plugin, add it to the ~qpsmtpd/config/plugins file as usual.
+It should precede any plugins whose rejections you wish to override.  You may
+have to alter those plugins to check the appropriate notes field.
+
+Several configuration files are supported, corresponding to different
+parts of the SMTP conversation:
+
+=over 4
+
+=item whitelist_zones
+
+Any IP address listed in the whitelist_zones file is queried using
+the connecting MTA's IP address.  Any A or TXT answer is means that the
+remote HOST address can be selectively exempted at other stages by plugins
+testing for a 'whitelisthost' connection note.
+
+NOTE: other 'connect' hooks will continue to fire (e.g. dnsbl), since the DNS
+queries happen in the background.  This plugin's 'rcpt_handler' retrieves
+the results of the query and sets the connection note if found.
+
+=head1 AUTHOR
+
+John Peacock <jpeacock@rowman.com>
+
+Based on the 'whitelist_soft' plugin by Gavin Carr <gavin@openfusion.com.au>,
+based on the 'whitelist' plugin by Devin Carraway <qpsmtpd@devin.com>.

+=head1 NAME
+
+denysoft_greylist
+
+=head1 DESCRIPTION
+
+Plugin to implement the 'greylisting' algorithm proposed by Evan 
+Harris in http://projects.puremagic.com/greylisting/. Greylisting is 
+a form of denysoft filter, where unrecognised new connections are 
+temporarily denied for some initial period, to foil spammers using 
+fire-and-forget spamware, http_proxies, etc.
+
+Greylisting adds two main features: it tracks incoming connections 
+using a triplet of remote IP address, sender, and recipient, rather 
+than just using the remote IP; and it uses a set of timeout periods 
+(black/grey/white) to control whether connections are allowed, instead 
+of using connection counts or rates.
+
+This plugin allows connection tracking on any or all of IP address, 
+sender, and recipient (but uses IP address only, by default), with 
+configurable greylist timeout periods. A simple dbm database is used 
+for tracking connections, and relayclients are always allowed 
+through. The plugin supports whitelisting using the whitelist_soft
+plugin (optional).
+
+
+=head1 CONFIG
+
+The following parameters can be passed to denysoft_greylist:
+
+=over 4
+
+=item remote_ip <bool>
+
+Whether to include the remote ip address in tracking connections.
+Default: 1.
+
+=item sender <bool>
+
+Whether to include the sender in tracking connections. Default: 0.
+
+=item recipient <bool>
+
+Whether to include the recipient in tracking connections. Default: 0.
+
+=item deny_late <bool>
+
+Whether to defer denials during the 'mail' hook until 'data_post'
+e.g. to allow per-recipient logging. Default: 0.
+
+=item black_timeout <timeout_seconds>
+
+The initial period, in seconds, for which we issue DENYSOFTs for 
+connections from an unknown (or timed out) IP address and/or sender
+and/or recipient (a 'connection triplet'). Default: 50 minutes.
+
+=item grey_timeout <timeout_seconds>
+
+The subsequent 'grey' period, after the initial black blocking period,
+when we will accept a delivery from a formerly-unknown connection
+triplet. If a new connection is received during this time, we will 
+record a successful delivery against this IP address, which whitelists 
+it for future deliveries (see following). Default: 3 hours 20 minutes.
+
+=item white_timeout <timeout_seconds>
+
+The period after which a known connection triplet will be considered 
+stale, and we will issue DENYSOFTs again. New deliveries reset the 
+timestamp on the address and renew this timeout. Default: 36 days.
+
+=item mode ( denysoft | testonly | off )
+
+Operating mode. In 'denysoft' mode we log and track connections and 
+issue DENYSOFTs for black connections; in 'testonly' mode we log and 
+track connections as normal, but never actually issue DENYSOFTs 
+(useful for seeding the database and testing without impacting 
+deliveries); in 'off' mode we do nothing (useful for turning 
+greylisting off globally if using per_recipient configs). 
+Default: denysoft.
+
+=item per_recipient <bool>
+
+Flag to indicate whether to use per-recipient configs. 
+
+=item per_recipient_db <bool>
+
+Flag to indicate whether to use per-recipient greylisting 
+databases (default is to use a shared database).
+
+=back
+
+=head1 BUGS
+
+Database locking is implemented using flock, which may not work on 
+network filesystems e.g. NFS. If this is a problem, you may want to
+use something like File::NFSLock instead.

+directory, after creating the directory with 0700 rights.  If you need a
+directory with different rights (say for an antivirus daemon), you will
+need to use the base function $self->qp->temp_dir() which takes a single

+#
+
+=head1 NAME
+
+hbedv - plugin for qpsmtpd which calls the H+BEDV anti virus scanner 
+
+=head1 DESCRIPTION
+
+The B<hbedv> plugin checks a mail for viruses with the H+BEDV anti virus
+scanner (see L<http://www.antivir.de/> for info). It can deny mails if a 
+virus was found with a configurable deny list.
+
+=head1 VERSION
+
+this is B<hbedv> version 1.1
+
+=head1 CONFIGURATION
+
+Add (perl-)regexps to the F<hbedv_deny> configuration file, one per line for the
+virii you want to block, e.g.:
+
+  Worm\/Sober\..*
+  Worm\/NetSky\..*
+
+or just 
+
+  .*
+
+to block any virus ;)
+
+Set the location of the binary with 
+
+  hbedv hbedvscanner /path/to/antivir
+
+in the plugin config if qpsmtpd, the location defaults to I</usr/bin/antivir>. 
+
+=head1 NOTES
+
+If the hbedv_deny config file is empty or could not be found, any virus 
+will be blocked.
+
+This plugin started life as a copy of the B<clamav> plugin. 
+
+=head1 LICENCE
+
+Written by Hanno Hecker E<lt>hah@uu-x.deE<gt>. 
+
+The B<hbedv> plugin is published under the same licence as qpsmtpd itself.

+=head1 NAME
+
+clamdscan
+
+=head1 DESCRIPTION
+
+A qpsmtpd plugin for virus scanning using the ClamAV scan daemon, clamd.
+
+=head1 RESTRICTIONS
+
+The ClamAV scan daemon, clamd, must have at least read access to the
+qpsmtpd spool directory in order to sucessfully scan the messages.  You can
+ensure this by running clamd as the same user as qpsmtpd does (by far the
+easiest method) or by doing the following: 
+
+=over 4
+
+=item * Change the group ownership of the spool directory to be a group 
+of which clamav is a member or add clamav to the same group as the qpsmtpd
+user.
+
+=item * Enable the "AllowSupplementaryGroups" option in clamd.conf.
+
+=item * Change the permissions of the qpsmtpd spool directory to 0750 (this 
+will emit a warning when the qpsmtpd service starts up, but can be safely
+ignored).
+
+=item * Make sure that all directories above the spool directory (to the
+root) are g+x so that the group has directory traversal rights; it is not
+necessary for the group to have any read rights except to the spool
+directory itself.
+
+=back
+
+It may be helpful to temporary grant the clamav user a shell and test to
+make sure you can cd into the spool directory and read files located there.
+Remember to remove the shell from the clamav user when you are done
+testing.
+
+=head1 INSTALL AND CONFIG
+
+Place this plugin in the plugin/virus directory beneath the standard
+qpsmtpd installation.  If you installed clamd with the default path, you
+can use this plugin with default options (nothing specified):
+
+=over 4
+
+=item B<clamd_socket>
+
+Full path to the clamd socket (the recommended mode); defaults to
+/tmp/clamd and is the default method.
+
+=item B<clamd_port>
+
+If present, must be the TCP port where the clamd service is running,
+typically 3310; default disabled.
+
+=item B<deny_viruses>
+
+Whether the scanner will automatically delete messages which have viruses.
+Takes either 'yes' or 'no' (defaults to 'yes').  If set to 'no' it will add
+a header to the message with the virus results.
+
+=item B<max_size>
+
+The maximum size, in kilobytes, of messages to scan; defaults to 128k.
+
+=back
+
+=head1 REQUIREMENTS

Subject: [PATCH 0373/1467] Import Danga libraries. This is a bit evil but
 we'll just have to track them from the Danga project. This way we get
 something stable that we know works, plus nobody has to go and track down
 other libraries.

Note that only Danga::Socket is (C) Danga. Everything else is original code
and (C) Matt Sergeant.

+=head1 NAME
+
+Danga::DNS - a DNS lookup class for the Danga::Socket framework
+
+=head1 SYNOPSIS
+
+  Danga::DNS->new(%options);
+
+=head1 DESCRIPTION
+
+This module performs asynchronous DNS lookups, making use of a single UDP
+socket (unlike Net::DNS's bgsend/bgread combination), and blocking reading on
+a client until the response comes back (this is useful for e.g. SMTP rDNS
+lookups where you want the answer before you see the next SMTP command).
+
+Currently this module will only perform A or PTR lookups. A rDNS (PTR) lookup
+will be performed if the host matches the regexp: C</^\d+\.\d+\.\d+.\d+$/>.
+
+The lookups time out after 15 seconds.
+
+=head1 API
+
+=head2 C<< Danga::DNS->new( %options ) >>
+
+Create a new DNS query. You do not need to store the resulting object as this
+class is all done with callbacks.
+
+Example:
+
+  Danga::DNS->new(
+    callback => sub { print "Got result: $_[0]\n" },
+    host => 'google.com',
+    );
+
+=over 4
+
+=item B<[required]> C<callback>
+
+The callback to call when results come in. This should be a reference to a
+subroutine. The callback receives two parameters - the result of the DNS lookup
+and the host that was looked up.
+
+=item C<host>
+
+A host name to lookup. Note that if the hostname is a dotted quad of numbers then
+a reverse DNS (PTR) lookup is performend.
+
+=item C<hosts>
+
+An array-ref list of hosts to lookup.
+
+B<NOTE:> One of either C<host> or C<hosts> is B<required>.
+
+=item C<client>
+
+It is possible to specify a C<Danga::Client> object (or subclass) which you wish
+to disable for reading until your DNS result returns.
+
+=item C<type>
+
+You can specify one of: I<"A">, I<"PTR"> or I<"TXT"> here. Other types may be
+supported in the future.

Subject: [PATCH 0384/1467] Add plugable logging support include sample plugin
 which replicates the existing core code.  Add OK hook.

*  lib/Qpsmtpd.pm
   (init_logger): replaced with log_level()
   (load_logging): NEW - load logging plugins without calling log()
   (log_level): NEW - set/get global $LogLevel scalar
   (log): now just a wrapper for varlog(); called only by core code
   (varlog): initializes logging if not already done, calls logging plugins
     in turn and falls back to interal logging unless plugins OK or DECLINED
   (_load_plugins): only display "Loading plugin" when actually loading one
   (run_hooks): load logging plugins without calling log(); add OK hook as
     else of the DENY* case
   (spool_dir): use global $Spool_dir scalar to cache location

*  lib/Qpsmtpd/Plugin.pm
   (%hooks): add "logging" and "ok"
   (register_hook): add local _hook to object cache
   (log): call varlog() with additional parameters hook and plugin_name
     except for logging hook
   (compile): add accessor sub for local _hook scalar

*  lib/Qpsmtpd/SMTP.pm
   (mail, rcpt): change loglevel to LOGALERT instead of LOGWARN for from/to

*  qpsmtpd-forkserver
   (REAPER): use package ::log() instead of warn()
   (main): defer calling log until $plugin_loader has been initialized
   (log): call logging using the $plugin_loader object

*  plugins/logging/warn
   NEW: sample plugin which replicates the core logging functionality

*  plugins/logging/devnull
   NEW: sample plugin which logs nothing (for testing multiple logging
     plugin functionality)

*  config.sample/logging
   sample configuration file for logging plugins

*  plugins/virus/uvscan
   plugins/virus/clamav
   Increase loglevel for non-serious warnings to LOGWARN from LOGERROR

Subject: [PATCH 0387/1467] Revamp Qpsmtpd::Constants so it is possible to
 retrieve the text representation from the numeric (for logging purposes). 
 Add new logging plugin, logging/adaptive, which logs at different levels
 depending on whether the message was accepted/rejected.

 *  lib/Qpsmtpd/Constants.pm
    use hashes for storing return_codes and log_levels
    export accessor methods to retrieve the text representations

 *  lib/Qpsmtpd.pm
    Rename log_level() to trace_level() so as to not conflict with the same
    name in Qpsmtpd::Constants.
    Call return_code() to display the text form when logging

 *  plugins/logging/adaptive
    Better documentation
    Support named parameters and prefix
    Call return_code() to display the text form when logging

 *  plugins/logging/warn
    Include POD

 *  README.logging
    First pass at documenting the logging plugin API

 *  config.sample/loglevel
    New numbering scheme to map directly to syslog levels

+=head1 qpsmtpd logging system; developer documentation
+
+Qpsmtpd now (as of 0.30-dev) supports a plugable logging architecture, so
+that different logging plugins can be supported.  See the example logging
+plugins in plugins/logging, specifically the L<plugins/logging/warn> and
+L<plugins/logging/adaptive> files for examples of how to write your own
+logging plugins.
+
+=head1 Internal support for pluggable logging
+
+Any code in the core can call C<$self->log()> and those log lines will be
+dispatched to each of the registered logging plugins.  When C<log()> is
+called from a plugin, the plugin and hook names are automatically included
+in the parameters passed the logging hooks.  All plugins which register for
+the logging hook should expect the following parameters to be passed:
+
+  $self, $transaction, $trace, $hook, $plugin, @log
+
+where those terms are:
+
+=over 4
+
+=item C<$self>
+
+The object which was used to call the log() method; this can be any object
+within the system, since the core code will automatically load logging
+plugins on behalf of any object.
+
+=item C<$transaction>
+
+This is the current SMTP transaction (defined as everything that happens
+between HELO/EHLO and QUIT/RSET).  If you want to defer outputting certain
+log lines, you can store them in the transaction object, but you will need
+to bind the C<reset_transaction> hook in order to retrieve that information
+before it is discarded when the transaction is closed (see the
+L<logging/adaptive> plugin for an example of doing this).
+
+=item C<$trace>
+
+This is the log level (as shown in config.sample/loglevel) that the caller
+asserted when calling log().  If you want to output the textural
+representation (e.g. C<LOGERROR>) of this in your log messages, you can use
+the log_level() function exported by Qpsmtpd::Constants (which is
+automatically available to all plugins).
+
+=item C<$hook>
+
+This is the hook that is currently being executed.  If log() is called by
+any core code (i.e. not as part of a hook), this term will be C<undef>.
+
+=item C<$plugin>
+
+This is the plugin name that executed the log().  Like C<$hook>, if part of
+the core code calls log(), this wil be C<undef>.  See L<logging/warn> for a
+way to prevent logging your own plugin's log entries from within that
+plugin (the system will not infinitely recurse in any case).
+
+=item C<@log>
+
+The remaining arguments are as passed by the caller, which may be a single
+term or may be a list of values.  It is usually sufficient to call 
+C<join(" ",@log)> to deal with these terms, but it is possible that some
+plugin might pass additional arguments with signficance.
+
+=back
+
+Note: if you register a handler for certain hooks, e.g. C<deny>, there may
+be additional terms passed between C<$self> and C<$transaction>.  See
+L<logging/adaptive> for and example.

+=head1 NAME
+
+adaptive - An adaptive logging plugin for qpsmtpd
+
+=head1 DESCRIPTION
+
+A qpsmtpd plugin for logging at different levels depending on success or
+failure of any given message.
+
+=head1 INSTALL AND CONFIG
+
+Place this plugin in the plugin/logging directory beneath the standard
+qpsmtpd installation.  Edit the config/logging file and add a line like
+this:
+
+  logging/adaptive [accept minlevel] [reject maxlevel] [prefix char]
+
+where the optional parameters are:
+
+=over 4
+
+=item B<accept>
+
+This is the level at which messages which are accepted will be logged.  You
+can use either the loglevel number (as shown in config.sample/loglevels) or
+you can use the text form (from the same file).  Typically, you would set
+this to LOGERROR (4) so that the FROM and TO lines would be logged (with the
+default installation).  If absent, it will be set to LOGERROR (4).
+
+=item B<reject>
+
+This is the level which messages which are rejected for any reason will be 
+logged.  This would typically be set as high as reasonable, to document why a
+message may have been rejected.  If absent, it defaults to LOGWARN (5), which
+is probably not high enough for most sites.
+
+=item B<prefix>
+
+In order to visually distinguish the accepted from rejected lines, all
+log lines from a rejected message will be prefixed with the character
+listed here (directly after the PID).  You can use anything you want as
+a prefix, but it is recommended that it be short (preferably just a single
+character) to minimize the amount of bloat in the log file.  If absent, the
+prefix defaults to the exclamation point (!).

+  ...
+
+=head1 DESCRIPTION
+
+This plugin implements a very simple authentication plugin using a flat password
+file containing username and password separated by colons.
+
+Note that this plugin enforces the use of a full email address (including
+@domain) as the username. There's no particular reason for this so feel free
+to modify the code to suit your setup.
+
+The password is stored on disk unencrypted, however authentication uses a HMAC
+algorithm so no password is transfered in the clear.

+=head1 NAME
+
+auth_ldap_bind - Authenticate user via an LDAP bind
+
+=head1 DESCRIPTION
+
+This plugin authenticates users against an LDAP Directory.  The plugin
+first performs a lookup for an entry matching the connecting user.  This
+lookup uses the 'ldap_auth_filter_attr' attribute to match the connecting
+user to their LDAP DN.  Once the plugin has found the user's DN, the plugin
+will attempt to bind to the Directory as that DN with the password that has
+been supplied.
+
+=head1 CONFIGURATION
+
+Configuration items can be held in either the 'ldap' configuration file, or as
+arguments to the plugin.
+
+Configuration items in the 'ldap' configuration file
+are set one per line, starting the line with the configuration item key,
+followed by a space, then the values associated with the configuration item.
+
+Configuration items given as arguments to the plugin are keys and values
+separated by spaces.  Be sure to quote any values that have spaces in them.
+
+The only configuration item which is required is 'ldap_base'.  This tells the
+plugin what your base DN is.  The plugin will not work until it has been
+configured.
+
+The configuration items 'ldap_host' and 'ldap_port' specify the host and port
+at which your Directory server may be contacted.  If these are not specified,
+the plugin will use port '389' on 'localhost'.
+
+The configuration item 'ldap_timeout' specifies how long the plugin should
+wait for a response from your Directory server.  By default, the value is 5
+seconds.
+
+The configuration item 'ldap_auth_filter_attr' specifies how the plugin should
+find the user in your Directory.  By default, the plugin will look up the user
+based on the 'uid' attribute.
+
+=head1 NOTES
+
+Each auth requires an initial lookup to find the user's DN.  Ideally, the
+plugin would simply bind as the user without the need for this lookup(see
+FUTURE DIRECTION below).
+
+This plugin requires that the Directory allow anonymous bind (see FUTURE
+DIRECTION below).
+
+=head1 FUTURE DIRECTION
+
+A configurable LDAP filter should be made available, to account for users
+who are over quota, have had their accounts disabled, or whatever other
+arbitrary requirements.
+
+A configurable DN template (uid=$USER,ou=$DOMAIN,$BASE).  This would prevent
+the need of the initial user lookup, as the DN is created from the template.
+
+A configurable bind DN, for Directories that do not allow anonymous bind.
+
+Another plugin ('ldap_auth_cleartext'?), to allow retrieval of plain-text
+passwords from the Directory, permitting CRAM-MD5 or other hash algorithm
+authentication.

Subject: [PATCH 0411/1467] First, since EventLoop goes off and does other
 things, any PostLoopCallback can signal "our" EventLoop to return.  To ensure
 we wait the full time, we must loop around until the end condition is truly
 satisfied.

Subject: [PATCH 0414/1467]  *   qpsmtpd-forkserver      Create a single
 Qpsmtpd::TcpServer object in the parent process and      then rely on fork to
 let each child have it's own copy

 *   lib/Qpsmtpd/Plugin.pm
     Add new pre-connection and post-connection hooks

 *   README.plugins
     Document the above new hooks

 *   lib/Qpsmtpd.pm
     No longer have local value for trace_level() the first time through, which
     was masking the global value (due to stupid search/replace error).
     Don't call log() from trace_level() since it is only ever called from
     within the varlog() sub when no logging plugin is registered.

 *   plugins/dnsbl
     Config line option to use DENY_DISCONNECT instead of DENY (since any IP
     on a blacklist should not have a chance to send anything for now).
     Add POD to document the new disconnect behavior

 *   lib/Qpsmtpd.pm
     Compatibility changes so test files continue to work

 *   t/Test/Qpsmtpd.pm
     Compatibility sub for core subs which call varlog() directly

+Add the following line to the config/plugins file:
+
+  dnsbl [disconnect]
+
+If you want to immediately drop the connection (since some blacklisted 
+servers attempt multiple sends per session), add the optional keyword 
+"disconnect" (case insensitive) to the config line.  In most cases, an

+a new transaction, since even the most volatile blacklists will return
+the same answer for a short period of time (the minimum DNS cache period).

+
+This plugin checks the badrcptto_patterns config. This allows
+special patterns to be denied (e.g. percent hack, bangs, 
+double ats).
+
+=head1 CONFIG
+
+config/badrcptto_patterns
+
+Patterns are stored in the format pattern\sresponse, where pattern
+is a Perl pattern expression. Don't forget to anchor the pattern if
+you want to restrict it from matching anywhere in the string.
+
+qpsmtpd already ensures that the address contains an @, with something
+to the left and right of the @.

+=head1 SYNOPSIS
+
+This plugin checks the norelayclients config file to see if 
+relaying is denied.
+
+This allows specific clients, such as the gateway, to be denied 
+relaying, even though they would be allowed relaying by the 
+relayclients file.
+
+=head1 CONFIG
+
+config/norelayclients
+
+Each line is:
+- a full IP address
+- partial IP address terminated by a dot for matching whole networks
+  e.g. 192.168.42.
+
+=head1 BUGS AND LIMITATIONS
+
+This plugin does not have a more_norelayclients map equivalent
+of the more_relayclients map of the check_relay plugin.
+

+
+Based on check_relay plugin from the qpsmtpd distribution.

+
+auth_cvm_unix_local - SMTP AUTH LOGIN module using 
+Bruce Guenther's Credential Validation Module (CVM) 
+    http://untroubled.org/cvm/
+
+=head1 SYNOPSIS
+
+In config/plugins:
+
+  auth/auth_cvm_unix_local \
+	cvm_socket /var/lib/cvm/cvm-unix-local.socket	\
+	enable_smtp no \
+	enable_ssmtp yes
+
+=head1 BUGS
+
+- Should probably handle auth-cram-md5 as well. However, this requires
+access to the plain text password. We could store a separate database
+of passwords purely for SMTP AUTH, for example as an optional 
+SMTPAuthPassword property of an account in the esmith::AccountsDB;

+=head1 NAME
+
+check_loop - Detect mail loops
+
+=head1 DESCRIPTION
+
+This plugin detects loops by counting "Received" and "Delivered-To"
+header lines.  It's a kluge but it duplicates what qmail-smtpd does,
+and it does at least prevent messages from looping forever.
+
+=head1 CONFIGURATION
+
+Takes one optional parameter, the maximum number of "hops" ("Received"
+and lines plus "Delivered-To" lines) allowed.  The default is 100, the
+same as in qmail-smtpd.
+
+=head1 AUTHOR
+
+Written by Keith C. Ivey
+
+=head1 LICENSE
+
+Released to the public domain, 17 June 2005.

Subject: [PATCH 0428/1467] Change remaining plugins to use LOGXXXX constants
 instead of bare numbers. Change plugins/dnsbl to permit AUTH'd or other relay
 clients even if IP is on a blacklist.

Subject: [PATCH 0429/1467]  Switch sense of adaptive logging.  Immediately
 echo log lines <= max level  and save log lines <= min level.  IIF a message
 is accepted for delivery,  then echo out the saved log lines (typically just
 FROM and TO) with the prefix  for multilog filtering into independent log
 files.

 Update POD in logging/adaptive to describe changed behavior as well as give
 an example log/run file to filter the messages accordingly.

 In order to visually distinguish the accepted from rejected lines, all
-log lines from a rejected message will be prefixed with the character
+log lines from a accepted message will be prefixed with the character
 listed here (directly after the PID).  You can use anything you want as
 a prefix, but it is recommended that it be short (preferably just a single
 character) to minimize the amount of bloat in the log file.  If absent, the
-prefix defaults to the exclamation point (!).
+prefix defaults to the left single quote (`).

+
+If you are using multilog to handle your logging, you can replace the system
+provided log/run file with something like this:
+
+  #! /bin/sh
+  export LOGDIR=./main
+  mkdir -p $LOGDIR/failed
+  exec multilog t n10 \
+         '-*` *' $LOGDIR/detailed \
+    '-*' '+*` *' $LOGDIR/accepted
+
+which will have the following effects:
+
+=over 4
+
+=item 1. All lines will be logged into the ./mail/detailed folder
+
+=item 2. Log lines for messages that are accepted will go to ./main/accepted
+
+=back
+
+You may want to use the s####### option to multilog to ensure that the log
+files are large enough to maintain a proper amount of history.  Depending on
+your site load, it is useful to have at least a week and preferrably three
+weeks of accepted messages.  You can also use the n## option to have more
+log history files maintained.

+=head1 NAME
+
+sophie scanner
+
+=head1 DESCRIPTION
+
+A qpsmtpd plugin for virus scanning using the SOPHOS scan daemon, Sophie.
+
+=head1 RESTRICTIONS
+
+The Sophie scan daemon must have at least read access to the qpsmtpd spool
+directory in order to sucessfully scan the messages.  You can ensure this
+by running Sophie as the same user as qpsmtpd does (by far the easiest
+method) or by doing the following: 
+
+=over 4
+
+=item * Change the group ownership of the spool directory to be a group 
+of which the Sophie user is a member or add the Sophie user to the same group
+as the qpsmtpd user.
+
+=item * Change the permissions of the qpsmtpd spool directory to 0750 (this 
+will emit a warning when the qpsmtpd service starts up, but can be safely
+ignored).
+
+=item * Make sure that all directories above the spool directory (to the
+root) are g+x so that the group has directory traversal rights; it is not
+necessary for the group to have any read rights except to the spool
+directory itself.
+
+=back
+
+It may be helpful to temporary grant the Sophie user a shell and test to
+make sure you can cd into the spool directory and read files located there.
+Remember to remove the shell from the Sophieav user when you are done
+testing.
+
+Note also that the contents of config/spool_dir must be the full path to the
+spool directory (not a relative path) in order for the scanner to locate the
+file.
+
+=head1 INSTALL AND CONFIG
+
+Place this plugin in the plugin/virus directory beneath the standard
+qpsmtpd installation.  If you installed Sophie with the default path, you
+can use this plugin with default options (nothing specified):
+
+=over 4
+
+=item B<Sophie_socket>
+
+Full path to the Sophie socket defaults to /var/run/Sophie.
+
+=item B<deny_viruses>
+
+Whether the scanner will automatically delete messages which have viruses.
+Takes either 'yes' or 'no' (defaults to 'yes').  If set to 'no' it will add
+a header to the message with the virus results.
+
+=item B<max_size>
+
+The maximum size, in kilobytes, of messages to scan; defaults to 128k.
+
+=back
+
+=head1 REQUIREMENTS
+
+This module requires the Sophie daemon, available here:
+
+L<http://www.clanfield.info/sophie/>
+
+which in turn requires the libsavi.so library (available with the Sophos
+Anti-Virus for Linux or Unix).
+
+The following changes to F</etc/sophie.cfg> B<should> be made:
+
+=over 4
+
+=item user: qmaild
+
+Change the "user" parameter to match the qpsmtpd user.
+
+=item group: nofiles
+
+Change the "group" parameter to match the qpsmtpd group.
+
+=item umask: 0001
+
+If you don't change the umask, only the above user/group will be able to scan.
+
+=back
+
+The following changes to F</etc/sophie.savi> B<must> be made:
+
+=over 4
+
+=item Mime: 1
+
+This option will permit the SAVI engine to directly scan e-mail messages.

Subject: [PATCH 0443/1467] bump version to 0.31-dev

	From: 	  hjp@hjp.at
	Subject: 	PATCH: Return 421 if we are going to disconnect
	Date: 	July 3, 2005 1:23:21 PM PDT
	To: 	  qpsmtpd@perl.org

RFC 2821 says we should return 421, if we disconnect, not 450 or 451.

+=head1 Naming Conventions
+
+Plugins should be written using standard named hook subroutines.  This
+allows them to be overloaded and extended easily.
+
+Because some of our callback names have characters invalid in
+subroutine names, they must be translated.  The current translation
+routine is: C< s/\W/_/g; >

+=head1 Register
+
+If you choose not to use the default naming convention, you need to
+register the hooks in your plugin.  You do this with the C< register >
+method call on the plugin object.
+
+  sub register {
+    my ($self, $qp) = @_;
+
+    $self->register_hook('mail', 'mail_handler');
+    $self->register_hook('rcpt', 'rcpt_handler');
+    $self->register_hook('disconnect', 'disconnect_handler');
+  }
+
+  sub mail_handler { ... }
+  sub rcpt_handler { ... }
+  sub disconnect_handler { ... }
+
+A single plugin can register as many hooks as it wants, and can
+register a hook multiple times.
+
+The C< register > method is also often used for initialization and
+reading configuration.
+
+=head1 Init
+
+The 'init' method is the first method called after a plugin is
+loaded.  It's mostly for inheritance, below.
+
+=head1 Inheritance
+
+Instead of modifying @ISA directly in your plugin, use the 
+C< plugin_isa > method from the init subroutine.
+
+  # rcpt_ok_child
+  sub init {
+    my ($self, $qp) = @_;
+    $self->isa_plugin('rcpt_ok');
+  }
+
+  sub hook_rcpt {
+    my ($self, $transaction, $recipient) = @_;
+    # do something special here...
+    $self->SUPER::hook_rcpt( $transaction, $recipient );
+  }

+
+This plugin implements basic TLS support.
+
+If TLS is successfully negotiated then the C<tls_enabled> field in the
+Connection notes is set. If you wish to make TLS mandatory you should check
+that field and take appropriate action. Note that you can only do that from
+MAIL FROM onwards.

Subject: [PATCH 0469/1467]  r589@jpeacock:  jpeacock | 2005-07-10 06:54:32
 -0400  Track hooks as array and hash.  Re-revert changes to logging plugins
 to use new-style hooking.  logging/adaptive assumed that register() has been
 called before hook_logging.

Subject: [PATCH 0471/1467] If the PID file already exists at startup, truncate
 to zero-length before attempting to re-use it.  Otherwise if the new PID is
 shorter than the previous one the file will be corrupted by the rewrite
 (harmlessly the way it is being read by this code, but problematically for
 anything that expects to be able to run something similar to /bin/kill `cat
 /path/to/pid.file`)

+=head1 NAME
+
+Danga::DNS - a DNS lookup class for the Danga::Socket framework
+
+=head1 SYNOPSIS
+
+  Danga::DNS->new(%options);
+
+=head1 DESCRIPTION
+
+This module performs asynchronous DNS lookups, making use of a single UDP
+socket (unlike Net::DNS's bgsend/bgread combination), and blocking reading on
+a client until the response comes back (this is useful for e.g. SMTP rDNS
+lookups where you want the answer before you see the next SMTP command).
+
+Currently this module will only perform A or PTR lookups. A rDNS (PTR) lookup
+will be performed if the host matches the regexp: C</^\d+\.\d+\.\d+.\d+$/>.
+
+The lookups time out after 15 seconds.
+
+=head1 API
+
+=head2 C<< Danga::DNS->new( %options ) >>
+
+Create a new DNS query. You do not need to store the resulting object as this
+class is all done with callbacks.
+
+Example:
+
+  Danga::DNS->new(
+    callback => sub { print "Got result: $_[0]\n" },
+    host => 'google.com',
+    );
+
+=over 4
+
+=item B<[required]> C<callback>
+
+The callback to call when results come in. This should be a reference to a
+subroutine. The callback receives two parameters - the result of the DNS lookup
+and the host that was looked up.
+
+=item C<host>
+
+A host name to lookup. Note that if the hostname is a dotted quad of numbers then
+a reverse DNS (PTR) lookup is performend.
+
+=item C<hosts>
+
+An array-ref list of hosts to lookup.
+
+B<NOTE:> One of either C<host> or C<hosts> is B<required>.
+
+=item C<client>
+
+It is possible to specify a C<Danga::Client> object (or subclass) which you wish
+to disable for reading until your DNS result returns.
+
+=item C<type>
+
+You can specify one of: I<"A">, I<"PTR"> or I<"TXT"> here. Other types may be
+supported in the future.

Subject: [PATCH 0479/1467] These changes to trunk were missed when 0.31 was
 branched.

 r588@jpeacock (orig r490):  jpeacock | 2005-07-09 07:03:53 -0400
  r547@jpeacock:  jpeacock | 2005-07-02 07:20:17 -0400
  Replace pithy comment with something more neutral.
  Thanks Gordon Rowell <gordonr@gormand.com.au>
  r548@jpeacock:  jpeacock | 2005-07-02 07:24:21 -0400
  Example patterns for badrcptto plugin - Gordon Rowell <gordonr@gormand.com.au>
  r586@jpeacock:  jpeacock | 2005-07-09 06:54:47 -0400
  Don't use varlog() directly unless you are passing all parameters.
  Don't try to log() anything during loading of logging plugins.
  r587@jpeacock:  jpeacock | 2005-07-09 06:59:57 -0400
  Cannot use new-style hooking with logging plugins (yet).

 r590@jpeacock (orig r491):  jpeacock | 2005-07-10 06:56:55 -0400
  r589@jpeacock:  jpeacock | 2005-07-10 06:54:32 -0400
  Track hooks as array and hash.
  Re-revert changes to logging plugins to use new-style hooking.
  logging/adaptive assumed that register() has been called before hook_logging.

 few files and it cleaned up more than it changed.

Subject: [PATCH 0499/1467] Add --detach commandline option to forkserver; if
 supplied, daemonize just prior to entering the main accept loop.

Split handling of --pid-file so that preexisting pid files are dealt with and
the file is opened before priveleges are dropped, but the writing out of the
new file happens after dropping privs and (if applicable) forking the
daemonized process, so the correct PID is recorded.

+=head1 DESCRIPTION
+
+This plugin enqueues mail from qpsmtpd into Exim via BSMTP
+
+=head1 INSTALLATION
+
+The qpsmtpd user B<must> be configured in the I<trusted_users> setting
+in your Exim configuration.  If it is not, queueing will still work,
+but sender addresses will not be honored by exim, which will make all
+mail appear to originate from the smtpd user itself.
+
+=head1 CONFIGURATION
+
+The plugin accepts configuration settings in space-delimited name/value
+pairs.  For example:
+
+ queue/exim-bsmtp exim_path /usr/sbin/exim4
+
+=over 4
+
+=item exim_path I<path>
+
+The path to use to execute the Exim BSMTP receiver; by default this is
+I</usr/sbin/rsmtp>.  The commandline switch '-bS' will be added (this is
+actually redundant with rsmtp, but harmless).

 to allow specification of an explicit $QPSMTPD_CONFIG variable to specify
 where the config lives, overriding $QMAIL/control and /var/qmail/control if
 set.  The usual "last location with the file wins" rule still applies.

Subject: [PATCH 0520/1467] * lib/Qpsmtpd/TcpServer.pm   Don't try to load the
 plugins if they are already loaded.

* lib/Qpsmtpd/Transaction.pm
  Get the size_threshold by inheritance.
  Extract the spooling of the body as a new sub.
  Always spool the body when calling body_filename().
  Compare the body_size to the cached size_threshold.

* lib/Qpsmtpd.pm
  Cache the size_threshold and provide an accessor method.

* qpsmtpd-forkserver
  Initialize both the spool_dir and size_threshold caches before forking.

Subject: [PATCH 0525/1467] * lib/Qpsmtpd/Address.pm     Convert objects to
 hash.  Neuter parse() to wrapper around new().     Add overload stringify to
 $obj->format().

* t/qpsmtpd-address.t
    Remove tests specific to parse().  Add test for overloaded "".

Subject: [PATCH 0526/1467] * lib/Qpsmtpd/Transaction.pm     Fix fairly
 egregious error.  If the size_threashold is smaller than     the body while
 writing, the file handle would be closed prematurely.     Ouch.  I don't like
 it here from a stylistic point of view, but at     least it will actually
 work now.

+
+Qpsmtpd::Address - Lightweight E-Mail address objects
+
+=head1 DESCRIPTION
+
+Based originally on cut and paste from Mail::Address and including 
+every jot and tittle from RFC-2821/2822 on what is a legal e-mail 
+address for use during the SMTP transaction.
+
+=head1 USAGE
+
+  my $rcpt = Qpsmtpd::Address->new('<email.address@example.com>');
+
+The objects created can be used as is, since they automatically 
+stringify to a standard form, and they have an overloaded comparison 
+for easy testing of values.
+

+=head2 new()
+
+Can be called two ways:
+
+=over 4 
+
+=item * Qpsmtpd::Address->new('<full_address@example.com>')
+
+The normal mode of operation is to pass the entire contents of the 
+RCPT TO: command from the SMTP transaction.  The value will be fully 
+parsed via the L<canonify> method, using the full RFC 2821 rules.
+
+=item * Qpsmtpd::Address->new("user", "host")
+
+If the caller has already split the address from the domain/host,
+this mode will not L<canonify> the input values.  This is not 
+recommended in cases of user-generated input for that reason.  This 
+can be used to generate Qpsmtpd::Address objects for accounts like 
+"<postmaster>" or indeed for the bounce address "<>".
+
+=back
+
+The resulting objects can be stored in arrays or used in plugins to 
+test for equality (like in badmailfrom).

Subject: [PATCH 0538/1467] With PollServer, I get several unrecognized
 commands before the disconnect from plugins/count_unrecognized_commands kicks
 in.

Several buffered lines are read and processed by
Danga::Client::process_read_buf() without checking if the socket was
closed.  The attached patch seems to fix it.

Subject: [PATCH 0548/1467] * plugins/virus/clamdscan     Use LOGNOTICE instead
 of LOGERROR when bailing early due to     non-multipart message.

    Test clamd->ping() before scanning, and bail if it doesn't
    answer (with an appropriate error).

    Patch submitted by Dave Rolsky <autarch@urth.org>.

Subject: [PATCH 0549/1467] Drop root privileges before loading plugins, rather
 than after.  This reduces root exposure, and avoids (e.g.) files being
 created as root which then won't be writable by the normal qpsmtpd user.

Subject: [PATCH 0553/1467] Merge branches/0.3x back to trunk. Too many
 individual changes to document.  Trust me... ;-)

Lightly tested (i.e. it accepts and delivers mail with minimal plugins).

NOTES/LIMITATIONS:
logging/adaptive currently eats some log messages.
auth_vpopmail_sql is currently broken (needs continuations?).
'make test' fails in dnsbl (no Test::Qpsmtpd::input_sock() method).

+=head1 NAME
+
+Qpsmtpd::Address - Lightweight E-Mail address objects
+
+=head1 DESCRIPTION
+
+Based originally on cut and paste from Mail::Address and including 
+every jot and tittle from RFC-2821/2822 on what is a legal e-mail 
+address for use during the SMTP transaction.
+
+=head1 USAGE
+
+  my $rcpt = Qpsmtpd::Address->new('<email.address@example.com>');
+
+The objects created can be used as is, since they automatically 
+stringify to a standard form, and they have an overloaded comparison 
+for easy testing of values.
+
+=head1 METHODS
+
+=cut
+
+use overload (
+    '""'   => \&format,
+    'cmp'  => \&_addr_cmp,
+);
+
+=head2 new()
+
+Can be called two ways:
+
+=over 4 
+
+=item * Qpsmtpd::Address->new('<full_address@example.com>')
+
+The normal mode of operation is to pass the entire contents of the 
+RCPT TO: command from the SMTP transaction.  The value will be fully 
+parsed via the L<canonify> method, using the full RFC 2821 rules.
+
+=item * Qpsmtpd::Address->new("user", "host")
+
+If the caller has already split the address from the domain/host,
+this mode will not L<canonify> the input values.  This is not 
+recommended in cases of user-generated input for that reason.  This 
+can be used to generate Qpsmtpd::Address objects for accounts like 
+"<postmaster>" or indeed for the bounce address "<>".
+
+=back
+
+The resulting objects can be stored in arrays or used in plugins to 
+test for equality (like in badmailfrom).

+=head1 DESCRIPTION
+
+This plugin enqueues mail from qpsmtpd into Exim via BSMTP
+
+=head1 INSTALLATION
+
+The qpsmtpd user B<must> be configured in the I<trusted_users> setting
+in your Exim configuration.  If it is not, queueing will still work,
+but sender addresses will not be honored by exim, which will make all
+mail appear to originate from the smtpd user itself.
+
+=head1 CONFIGURATION
+
+The plugin accepts configuration settings in space-delimited name/value
+pairs.  For example:
+
+ queue/exim-bsmtp exim_path /usr/sbin/exim4
+
+=over 4
+
+=item exim_path I<path>
+
+The path to use to execute the Exim BSMTP receiver; by default this is
+I</usr/sbin/rsmtp>.  The commandline switch '-bS' will be added (this is
+actually redundant with rsmtp, but harmless).

Subject: [PATCH 0554/1467] Eliminate the creeping use of warn() in favor of
 log() and make more use of the "fd:#" code everywhere.

* lib/Qpsmtpd.pm
    Default log method use '$self->fd()' instead of '$self->{fd}'.
    Include a sub fd() method for inheritance purposes.

* lib/Qpsmtpd/PollServer.pm
    Inherit log() from Qpsmtpd.pm (via SMTP.pm).

* lib/Qpsmtpd/Plugin.pm
    Appropriate code allow plugins to inherit fd().

* plugins/dnsbl
    Use log() instead of warn().

* plugins/logging/adaptive
  plugins/logging/warn
    Include the 'fd:#' to the log line if defined.

* qpsmtpd
    Reorder things slightly so we can use log().

Subject: [PATCH 0562/1467] Fix problems with tls and relay_client.

* lib/Qpsmtpd/Connection.pm
    Abstract out parameters which can be reused (e.g. TLS) or can be
    set when creating the Connection object via start().

* plugins/tls
    Simplify code to use $self->clone() construct and also suppress
    IO::Socket::SSL debug noise, now that this is working.

* plugins/tls_cert
    New file to automate creating self-signed certificates for TLS.

Subject: [PATCH 0564/1467] the pre-connection and post-connection hooks are
 not working in qpsmtpd-forkserver. This patch merges Peter's patch (with the
 possibilty to DENY/DENSOFT the connection) and my first attempt. The
 --max-from-ip check was moved from core to the hosts_allow plugin.

Subject: [PATCH 0565/1467] this patch enables the configurable flags for the
 postfix-queue plugin. By default no flags are set (old behaviour). Known
 flags for cleanup are FLAG_FILTER, FLAG_BCC_OK and FLAG_MAP_OK, see POD for
 details.

+=head1 NAME 
+
+hosts_allow - decide if a host is allowed to send mail 
+
+=head1 DESCRIPTION
+
+The B<hosts_allow> module decides before the SMTP-Greeting if a host is
+allowed to connect. It checks for too many (running) connections from one
+host (see -m/--max-from-ip options in qpsmtpd-forkserver) and the config 
+file I<hosts_allow>.
+The plugin takes no arguments.
+
+=head1 CONFIG
+
+The config file contains lines with two or three items. The first is either
+an IP address or a network/mask pair. The second is a (valid) return code
+from Qpsmtpd::Constants. The last is a comment which will be returned to the
+connecting client if the return code is DENY or DENYSOFT (and of course 
+DENY_DISCONNECT and DENYSOFT_DISCONNECT). 
+Example:
+
+  192.168.3.4    DECLINED
+  192.168.3.0/24 DENY Sorry, known spam only source
+
+This would exclude 192.168.3.4 from the DENY of 192.168.3.0/24.

+=head1 NAME
+
+Qpsmtpd::DSN - Enhanced Mail System Status Codes - RFC 1893
+
+=head1 DESCRIPTION
+
+The B<Qpsmtpd::DSN> implements the I<Enhanced Mail System Status Codes> from
+RFC 1893.
+
+=head1 USAGE
+
+Any B<qpsmtpd> plugin can access these status codes. All sub routines are used
+the same way:
+ use Qpsmtpd::DSN;
+ ...;
+ return Qpsmtpd::DSN->relaying_denied();
+
+or
+
+ return Qpsmtpd::DSN->relaying_denied("Relaying from $ip denied");
+
+or 
+
+ return Qpsmtpd::DSN->relaying_denied(DENY,"Relaying from $ip denied");
+
+If no status message was given, it will use the predefined one from the 
+RFC. If the first argument is numeric, it will use this as a return code, 
+else the default return code is used. See below which default return code
+is used in the different functions.
+
+The first example will return 
+I<(DENY, "Relaying denied");>
+the others 
+I<(DENY, "Relaying from $ip denied");>
+which will be returned to qpsmtpd.
+
+In those sub routines which don't start with I<addr_, sys_, net_, proto_, 
+media_, sec_> I've added a default message which describes the status better
+than the RFC message.

 No, it really should be MIT licensed ("as per qpsmtpd") to go in the  distribution.
 There are a few exceptions (only your plugins at a cursory glance),  but those are mistakes.  :-)

 I don't have an issue with my qpsmtpd plugins being changed to state:

 This software is free software and may be distributed under the same

 Though as a distro maintainer, we do have a sizeable issue with license proliferation. It really is a bit of a nightmare when two licenses are almost, but not completely, the same.

 Thanks,

+=head1 NAME
+
+file - Simple log-to-file logging for qpsmtpd
+
+=head1 DESCRIPTION
+
+The 'file' logging plugin for qpsmtpd records qpsmtpd log messages into a
+file (or a named pipe, if you prefer.)
+
+=head1 CONFIGURATION
+
+To enable the logging plugin, add a line of this form to the qpsmtpd plugins
+configuration file:
+
+=over
+
+logging/file [loglevel I<level>] [reopen] [nosplit] I<path>
+
+For example:
+
+logging/file loglevel LOGINFO /var/log/qpsmtpd.log
+logging/file /var/log/qpsmtpd.log.%Y-%m-%d
+logging/file loglevel LOGCRIT reopen |/usr/local/sbin/page-sysadmin
+
+=back
+
+Multiple instances of the plugin can be configured by appending :I<N> for any
+integer(s) I<N>, to log to multiple files simultaneously, e.g. to log critical
+errors and normally verbose logs elsewhere.
+
+The filename or command given can include strftime conversion specifiers,
+which can be used to substitute time and date information into the logfile.
+The file will be reopened whenever this output changes (for example, with a
+format of qpsmtpd.log.%Y-%m-%d-%h, the log would be reopened once per hour).
+
+The list of supported conversion specifiers depends on the strftime()
+implementation of your C library. See strftime(3) for details.  Additionally,
+%i will be expanded to a (hopefully) unique session-id; if %i is used, a new
+logfile will be started for each SMTP connection.
+
+The following optional configuration setting can be supplied:
+
+=over
+
+=item nosplit
+
+If specified, the output file or pipe will be reopened at once once per
+connection, and only prior to the first log output.  This prevents logs for
+sessions that span log intervals being split across multiple logfiles.
+Without this option, the log will be reopened only when its output filename
+changes; if strftime specifiers are not used, the log will not be reopened
+at all.
+
+=item reopen
+
+Forces the log output to be reopened once per connection, as soon as something
+is available to be logged.  This can be combined with a high log severity (see
+I<loglevel> below) to facilitate SMTP service alarms with Nagios or a similar
+monitoring agent.
+
+=item loglevel I<loglevel>
+
+The internal log level below which messages will be logged.  The I<loglevel>
+given should be chosen from the list below.  Priorities count downward (for
+example, if LOGWARN were selected, LOGERROR, LOGCRIT and LOGEMERG messages
+would be logged as well).
+
+=over
+
+=item B<LOGDEBUG>
+
+=item B<LOGINFO>
+
+=item B<LOGNOTICE>
+
+=item B<LOGWARN>
+
+=item B<LOGERROR>
+
+=item B<LOGCRIT>
+
+=item B<LOGALERT>
+
+=item B<LOGEMERG>
+
+=back
+
+=back
+
+
+The chosen I<path> should be writable by the user running qpsmtpd; it will be
+created it did not already exist, and appended to otherwise.

+=head1 NAME
+
+syslog - Syslog logging plugin for qpsmtpd
+
+=head1 DESCRIPTION
+
+The syslog plugin for qpsmtpd passes qpsmtpd log messages into the standard
+UNIX syslog facility, mapping qpsmtpd priorities to syslog priorities.
+
+=head1 CONFIGURATION
+
+To enable the logging plugin, add a line of this form to the qpsmtpd plugins
+configuration file:
+
+=over
+
+logging/syslog [loglevel l] [priority p] [ident str] [facility f]
+
+For example:
+
+logging/syslog loglevel LOGINFO priority LOG_NOTICE
+
+=back
+
+The following optional configuration settings can be supplied:
+
+=over
+
+=item B<loglevel>
+
+The internal log level below which messages will be logged.  Priorities count
+downward as follows:
+
+=over
+
+=item B<LOGDEBUG>
+
+=item B<LOGINFO>
+
+=item B<LOGNOTICE>
+
+=item B<LOGWARN>
+
+=item B<LOGERROR>
+
+=item B<LOGCRIT>
+
+=item B<LOGALERT>
+
+=item B<LOGEMERG>
+
+=back
+
+
+=item B<priority>
+
+Normally, log messages will be mapped from the above log levels into the
+syslog(3) log levels of their corresponding names.  This will cause various
+messages to appear or not in syslog outputs according to your syslogd
+configuration (typically /etc/syslog.conf).  However, if the B<priority>
+setting is used, all messages will be logged at that priority regardless of 
+what the original priority might have been.
+
+=item B<ident>
+
+The ident string that will be attached to messages logged via this plugin.
+The default is 'qpsmtpd'.
+
+=item B<facility>
+
+The syslog facility to which logged mesages will be directed.  See syslog(3)
+for details.  The default is LOG_MAIL.

Subject: [PATCH 0577/1467] Apparently, I never tested TLS and AUTH at the same
 time.  It turns out that you have to explicitely read from <STDIN> in order
 for IO::Socket::SSL to correctly translate the data (i.e. reading from <>
 isn't sufficient).

 =head1 DESCRIPTION
 
-This plugin implements basic TLS support.
+This plugin implements basic TLS support.  It can also be used to support
+port 465 (SMTP over SSL), but only with qpsmtpd-forkserver.  In this case,
+be sure to load plugins/tls before any other connect plugins and start
+qpsmtpd like this:
+
+  qpsmtpd-forkserver --port 25 --port 465
+
+You can also specify multiple --listen-address options as well; see the help
+for qpsmtpd-forkserver for more details.
 
 If TLS is successfully negotiated then the C<tls_enabled> field in the
 Connection notes is set. If you wish to make TLS mandatory you should check

+=head1 NAME
+
+Qpsmtpd::Command - parse arguments to SMTP commands
+
+=head1 DESCRIPTION
+
+B<Qpsmtpd::Command> provides just one public sub routine: B<parse()>.
+
+This sub expects two or three arguments. The first is the name of the 
+SMTP command (such as I<HELO>, I<MAIL>, ...). The second must be the remaining
+of the line the client sent.
+
+If no third argument is given (or it's not a reference to a CODE) it parses 
+the line according to RFC 1869 (SMTP Service Extensions) for the I<MAIL> and 
+I<RCPT> commands and splitting by spaces (" ") for all other.
+
+Any module can supply it's own parsing routine by returning a sub routine 
+reference from a hook_*_parse. This sub will be called with I<$self>, I<$cmd>
+and I<$line>. 
+
+On successfull parsing it MUST return B<OK> (the constant from 
+I<Qpsmtpd::Constants>) success as first argument and a list of 
+values, which will be the arguments to the hook for this command.
+
+If parsing failed, the second returned value (if any) will be returned to the
+client as error message.
+
+=head1 EXAMPLE
+
+Inside a plugin 
+

+    my ($self, $transaction, $cmd) = @_;
+    return (OK, \&bdat_parser) if ($cmd eq 'bdat');

+=head1 NAME
+
+Authentication framework for qpsmtpd
+
+=head1 DESCRIPTION
+
+Provides support for SMTP AUTH within qpsmtpd transactions, see 
+
+L<http://www.faqs.org/rfcs/rfc2222.html>
+L<http://www.faqs.org/rfcs/rfc2554.html>
+
+for more details.
+
+=head1 USAGE
+
+This code is automatically loaded by Qpsmtpd::SMTP only if a plugin
+providing one of the defined L<Auth Hooks> is loaded.  The only
+time this can happen is if the client process employs the EHLO command to
+initiate the SMTP session.  If the client uses HELO, the AUTH command is
+not available and this module isn't even loaded.
+
+=head2 Plugin Design
+
+An authentication plugin can bind to one or more auth hooks or bind to all
+of them at once.  See L<Multiple Hook Behavior> for more details.
+
+All plugins must provide two functions:
+
+=over 4
+
+=item * init()
+
+This is the standard function which is called by qpsmtpd for any plugin 
+listed in config/plugins.  Typically, an auth plugin should register at
+least one hook, like this:
+
+
+  sub init {
+    my ($self, $qp) = @_;
+
+    $self->register_hook("auth", "authfunction");
+  }
+
+where in this case "auth" means this plugin expects to support any of 
+the defined authentication methods.
+
+=item * authfunction()
+
+The plugin must provide an authentication function which is part of
+the register_hook call.  That function will receive the following
+six parameters when called:
+
+=over 4
+
+=item $self
+
+A Qpsmtpd::Plugin object, which can be used, for example, to emit log
+entries or to send responses to the remote SMTP client.
+
+=item $transaction
+
+A Qpsmtpd::Transaction object which can be used to examine information
+about the current SMTP session like the remote IP address.
+
+=item $mechanism
+
+The lower-case name of the authentication mechanism requested by the
+client; either "plain", "login", or "cram-md5".
+
+=item $user
+
+Whatever the remote SMTP client sent to identify the user (may be bare
+name or fully qualified e-mail address).
+
+=item $clearPassword
+
+If the particular authentication method supports unencrypted passwords
+(currently PLAIN and LOGIN), which will be the plaintext password sent
+by the remote SMTP client.
+
+=item $hashPassword
+
+An encrypted form of the remote user's password, using the MD-5 algorithm
+(see also the $ticket parameter).
+
+=item $ticket
+
+This is the cryptographic challenge which was sent to the client as part
+of a CRAM-MD5 transaction.  Since the MD-5 algorithm is one-way, the same
+$ticket value must be used on the backend to compare with the encrypted
+password sent in $hashPassword.
+
+=back
+
+=back
+
+Plugins should perform whatever checking they want and then return one
+of the following values (taken from Qpsmtpd::Constants):
+
+=over 4
+
+=item OK
+
+If the authentication has succeeded, the plugin can return this value and
+all subsequently registered hooks will be skipped.
+
+=item DECLINED
+
+If the authentication has failed, but any additional plugins should be run, 
+this value will be returned.  If none of the registered plugins succeed, the
+overall authentication will fail.  Normally an auth plugin should return
+this value for all cases which do not succeed (so that another auth plugin
+can have a chance to authenticate the user).
+
+=item DENY
+
+If the authentication has failed, and the plugin wishes this to short circuit
+any further testing, it should return this value.  For example, a plugin could
+register the L<auth-plain> hook and immediately fail any connection which is
+not trusted (e.g. not in the same network).
+
+Another reason to return DENY over DECLINED would be if the user name matched
+an existing account but the password failed to match.  This would make a
+dictionary-based attack much harder to accomplish.  See the included
+auth_vpopmail_sql plugin for how this might be accomplished.
+
+By returning DENY, no further authentication attempts will be made using the
+current method and data.  A remote SMTP client is free to attempt a second
+auth method if the first one fails.
+
+=back
+
+Plugins may also return an optional message with the return code, e.g.
+
+  return (DENY, "If you forgot your password, contact your admin");
+
+and this will be appended to whatever response is sent to the remote SMTP
+client.  There is no guarantee that the end user will see this information,
+though, since some prominent MTA's (produced by M$oft) I<helpfully>
+hide this information under the default configuration.  This message will
+be logged locally, if appropriate, based on the configured log level.
+
+=head1 Auth Hooks
+
+The currently defined authentication methods are:
+
+=over 4
+
+=item * auth-plain
+
+Any plugin which registers an auth-plain hook will engage in a plaintext
+prompted negotiation.  This is the least secure authentication method since
+both the user name and password are visible in plaintext.  Most SMTP clients
+will preferentially choose a more secure method if it is advertised by the
+server.
+
+=item * auth-login
+
+A slightly more secure method where the username and password are Base-64
+encoded before sending.  This is still an insecure method, since it is
+trivial to decode the Base-64 data.  Again, it will not normally be chosen
+by SMTP clients unless a more secure method is not available (or if it fails).
+
+=item * auth-cram-md5
+
+A cryptographically secure authentication method which employs a one-way
+hashing function to transmit the secret information without significant
+risk between the client and server.  The server provides a challenge key
+L<$ticket>, which the client uses to encrypt the user's password.
+Then both user name and password are concatenated and Base-64 encoded before
+transmission.
+
+This hook must normally have access to the user's plaintext password,
+since there is no way to extract that information from the transmitted data.
+Since the CRAM-MD5 scheme requires that the server send the challenge
+L<$ticket> before knowing what user is attempting to log in, there is no way
+to use any existing MD5-encrypted password (like is frequently used with MySQL).
+
+=item * auth
+
+A catch-all hook which requires that the plugin support all three preceeding
+authentication methods.  Any plugins registering the auth hook will be run
+only after all other plugins registered for the specific authentication 
+method which was requested.  This allows you to move from more specific
+plugins to more general plugins (e.g. local accounts first vs replicated
+accounts with expensive network access later).
+
+=back
+
+=head2 Multiple Hook Behavior
+
+If more than one hook is registered for a given authentication method, then
+they will be tried in the order that they appear in the config/plugins file
+unless one of the plugins returns DENY, which will immediately cease all
+authentication attempts for this transaction.
+
+In addition, all plugins that are registered for a specific auth hook will
+be tried before any plugins which are registered for the general auth hook.

-Qpsmtpd::Auth - Authentication framework for qpsmtpd
-
-=head1 DESCRIPTION
-
-Provides support for SMTP AUTH within qpsmtpd transactions, see 
-
-L<http://www.faqs.org/rfcs/rfc2222.html>
-L<http://www.faqs.org/rfcs/rfc2554.html>
-
-for more details.
-
-=head1 USAGE
-
-This module is automatically loaded by Qpsmtpd::SMTP only if a plugin
-providing one of the defined L<Auth Hooks> is loaded.  The only
-time this can happen is if the client process employs the EHLO command to
-initiate the SMTP session.  If the client uses HELO, the AUTH command is
-not available and this module isn't even loaded.
-
-=head2 Plugin Design
-
-An authentication plugin can bind to one or more auth hooks or bind to all
-of them at once.  See L<Multiple Hook Behavior> for more details.
-
-All plugins must provide two functions:
-
-=over 4
-
-=item * register()
-
-This is the standard function which is called by qpsmtpd for any plugin 
-listed in config/plugins.  Typically, an auth plugin should register at
-least one hook, like this:
-
-
-  sub register {
-    my ($self, $qp) = @_;
-
-    $self->register_hook("auth", "authfunction");
-  }
-
-where in this case "auth" means this plugin expects to support any of 
-the defined authentication methods.
-
-=item * authfunction()
-
-The plugin must provide an authentication function which is part of
-the register_hook call.  That function will receive the following
-six parameters when called:
-
-=over 4
-
-=item $self
-
-A Qpsmtpd::Plugin object, which can be used, for example, to emit log
-entries or to send responses to the remote SMTP client.
-
-=item $transaction
-
-A Qpsmtpd::Transaction object which can be used to examine information
-about the current SMTP session like the remote IP address.
-
-=item $mechanism
-
-The lower-case name of the authentication mechanism requested by the
-client; either "plain", "login", or "cram-md5".
-
-=item $user
-
-Whatever the remote SMTP client sent to identify the user (may be bare
-name or fully qualified e-mail address).
-
-=item $clearPassword
-
-If the particular authentication method supports unencrypted passwords
-(currently PLAIN and LOGIN), which will be the plaintext password sent
-by the remote SMTP client.
-
-=item $hashPassword
-
-An encrypted form of the remote user's password, using the MD-5 algorithm
-(see also the $ticket parameter).
-
-=item $ticket
-
-This is the cryptographic challenge which was sent to the client as part
-of a CRAM-MD5 transaction.  Since the MD-5 algorithm is one-way, the same
-$ticket value must be used on the backend to compare with the encrypted
-password sent in $hashPassword.
-
-=back
-
-=back
-
-Plugins should perform whatever checking they want and then return one
-of the following values (taken from Qpsmtpd::Constants):
-
-=over 4
-
-=item OK
-
-If the authentication has succeeded, the plugin can return this value and
-all subsequently registered hooks will be skipped.
-
-=item DECLINED
-
-If the authentication has failed, but any additional plugins should be run, 
-this value will be returned.  If none of the registered plugins succeed, the
-overall authentication will fail.  Normally an auth plugin should return
-this value for all cases which do not succeed (so that another auth plugin
-can have a chance to authenticate the user).
-
-=item DENY
-
-If the authentication has failed, and the plugin wishes this to short circuit
-any further testing, it should return this value.  For example, a plugin could
-register the L<auth-plain> hook and immediately fail any connection which is
-not trusted (e.g. not in the same network).
-
-Another reason to return DENY over DECLINED would be if the user name matched
-an existing account but the password failed to match.  This would make a
-dictionary-based attack much harder to accomplish.  See the included
-auth_vpopmail_sql plugin for how this might be accomplished.
-
-By returning DENY, no further authentication attempts will be made using the
-current method and data.  A remote SMTP client is free to attempt a second
-auth method if the first one fails.
-
-=back
-
-Plugins may also return an optional message with the return code, e.g.
-
-  return (DENY, "If you forgot your password, contact your admin");
-
-and this will be appended to whatever response is sent to the remote SMTP
-client.  There is no guarantee that the end user will see this information,
-though, since some prominent MTA's (produced by M$oft) I<helpfully>
-hide this information under the default configuration.  This message will
-be logged locally, if appropriate, based on the configured log level.
-
-=head1 Auth Hooks
-
-The currently defined authentication methods are:
-
-=over 4
-
-=item * auth-plain
-
-Any plugin which registers an auth-plain hook will engage in a plaintext
-prompted negotiation.  This is the least secure authentication method since
-both the user name and password are visible in plaintext.  Most SMTP clients
-will preferentially choose a more secure method if it is advertised by the
-server.
-
-=item * auth-login
-
-A slightly more secure method where the username and password are Base-64
-encoded before sending.  This is still an insecure method, since it is
-trivial to decode the Base-64 data.  Again, it will not normally be chosen
-by SMTP clients unless a more secure method is not available (or if it fails).
-
-=item * auth-cram-md5
-
-A cryptographically secure authentication method which employs a one-way
-hashing function to transmit the secret information without significant
-risk between the client and server.  The server provides a challenge key
-L<$ticket>, which the client uses to encrypt the user's password.
-Then both user name and password are concatenated and Base-64 encoded before
-transmission.
-
-This hook must normally have access to the user's plaintext password,
-since there is no way to extract that information from the transmitted data.
-Since the CRAM-MD5 scheme requires that the server send the challenge
-L<$ticket> before knowing what user is attempting to log in, there is no way
-to use any existing MD5-encrypted password (like is frequently used with MySQL).
-
-=item * auth
-
-A catch-all hook which requires that the plugin support all three preceeding
-authentication methods.  Any plugins registering the auth hook will be run
-only after all other plugins registered for the specific authentication 
-method which was requested.  This allows you to move from more specific
-plugins to more general plugins (e.g. local accounts first vs replicated
-accounts with expensive network access later).
-
-=back
-
-=head2 Multiple Hook Behavior
-
-If more than one hook is registered for a given authentication method, then
-they will be tried in the order that they appear in the config/plugins file
-unless one of the plugins returns DENY, which will immediately cease all
-authentication attempts for this transaction.
-
-In addition, all plugins that are registered for a specific auth hook will
-be tried before any plugins which are registered for the general auth hook.

 =head1 DESCRIPTION
 
-This is an abstract base class which provides the basic framework for
-event-driven asynchronous IO.
+This is an abstract base class for objects backed by a socket which
+provides the basic framework for event-driven asynchronous IO,
+designed to be fast.  Danga::Socket is both a base class for objects,
+and an event loop.
+
+Callers subclass Danga::Socket.  Danga::Socket's constructor registers
+itself with the Danga::Socket event loop, and invokes callbacks on the
+object for readability, writability, errors, and other conditions.
+
+Because Danga::Socket uses the "fields" module, your subclasses must
+too.
+
+=head1 MORE INFO
+
+For now, see servers using Danga::Socket for guidance.  For example:
+perlbal, mogilefsd, or ddlockd.

 =head1 NAME
 
 domainkeys: validate a DomainKeys signature on an incoming mail
 
+=head1 SYNOPSIS
+
+  domainkeys [warn_only 1]
+
+Performs a DomainKeys validation on the message.  Takes a single
+configuration
+
+  warn_only 1
+
+which means that messages which are not correctly signed (i.e. signed but
+modified or deliberately forged) will not be DENY'd, but an error will still
+be issued to the logfile.

-=head1 DESCRIPTION
-
-This is an abstract base class for objects backed by a socket which
-provides the basic framework for event-driven asynchronous IO,
-designed to be fast.  Danga::Socket is both a base class for objects,
-and an event loop.
-
-Callers subclass Danga::Socket.  Danga::Socket's constructor registers
-itself with the Danga::Socket event loop, and invokes callbacks on the
-object for readability, writability, errors, and other conditions.
-
-Because Danga::Socket uses the "fields" module, your subclasses must
-too.
-
-=head1 MORE INFO
-
-For now, see servers using Danga::Socket for guidance.  For example:
-perlbal, mogilefsd, or ddlockd.

-Brad Fitzpatrick <brad@danga.com> - author
-
-Michael Granger <ged@danga.com> - docs, testing
-
-Mark Smith <junior@danga.com> - contributor, heavy user, testing
-
-Matt Sergeant <matt@sergeant.org> - kqueue support
-
-=head1 BUGS
-
-Not documented enough.
-
-tcp_cork only works on Linux for now.  No BSD push/nopush support.

+
+This plugin can be used for the case where a server is used as the smart
+relay host for internal users and external/authenticated users, but should
+not be considered a normal inbound MX server
+
+It should be configured to be run _AFTER_ check_relay and before other
+RCPT hooks!  Only clients that have authenticated or are listed in the
+relayclient file will be allowed to send mail.

Subject: [PATCH 0633/1467] (Working) support for multiple plugin directories,
 with a fix from  Nick Leverton <nj|@|leverton.org>.  The inner
 _load_plugins() routine is changed to load only a single plugin given a
 search path, and the (two) calls to it pass in the configured list of plugin
 dirs.  The non-module case of _load_plugin() simply loops on the plugin dir
 list until a matching plugin file is found; the first match stops the search
 for that plugin, regardless of success or failure in loading it.

Subject: [PATCH 0637/1467] Fixup qpsmtpd-prefork, et al, to correctly load
 Constants. Make child process pretty name optional for qpsmtpd-prefork.
 Ignore rather than crash for uninstalled plugins.

 0.3x
+  Instead of failing with cryptic message, ignore lines in config/plugins
+  for uninstalled plugins. (John Peacock)
+
+  Patch to prefork code to make it run (Leonardo Helman). Add --pretty
+  option to qpsmtpd-prefork to change $0 for child processes (John Peacock).
+
   Add support for multiple plugin directories, whose paths are given by the
   'plugin_dirs' configuration.  (Devin Carraway, Nick Leverton)

+=head1 SKIP PLUGINS API
+
+These functions allow to disable and re-enable loaded plugins. Loading 
+plugins after the initial loading phase is not possible. The earliest 
+place to disable a plugin is in C<hook_connect()>. 
+
+If you want to run a plugin just for some clients, load it like a usual 
+plugin and either hook it to the C<hook_connect()> (or any later hook) 
+and disable it there, use the C<skip_plugins> plugin or write your own 
+disabling plugin.
+
+These modifications of disabling/re-enabling a plugin are valid for the
+full connection, not transaction! For transaction based disabling of plugins,
+use the C<reset_transaction> hook to reset the list of disabled plugins. 
+
+A small warning: the C<reset_transaction> hook is called at least three
+times: after the client sent the C<(HE|EH)LO>, every time the client
+issues a C<MAIL FROM:> and after the mail was queued (or rejected by a 
+C<data_post> hook). Don't forget it is also called after C<RSET> and 
+connection closing (e.g. after C<QUIT>).

+=head1 NAME
+
+skip_plugins - don't run selected plugins for some hosts
+
+=head1 DESCRIPTION
+
+The B<skip_plugins> plugin allows you to skip selected plugins for some 
+clients. This is similar to some whitelist plugins, without the need to 
+modify any plugin. 
+
+This plugin should be run before any other plugins hooking to the
+I<hook_connect>. The config allows to run all plugins for one host in a 
+subnet and skip some for all other hosts in this network.
+
+=head1 CONFIG
+
+The config file I<skip_plugins> contains lines with two or three items per
+line. The first field is a network/mask pair (or just a single IP address).
+An action is set in the second field: currently B<continue> or B<skip> are 
+valid actions. 
+
+If a host matches a B<continue> line, the parsing is stopped and all 
+plugins are run for this host. A B<skip> action tells qpsmtpd to skip
+the plugins listed in the third field for this connection. 
+
+The plugin list in the third field must be separated by "," without any spaces.

-=head1 SKIP PLUGINS API
-
-These functions allow to disable and re-enable loaded plugins. Loading 
-plugins after the initial loading phase is not possible. The earliest 
-place to disable a plugin is in C<hook_connect()>. 
-
-If you want to run a plugin just for some clients, load it like a usual 
-plugin and either hook it to the C<hook_connect()> (or any later hook) 
-and disable it there, use the C<skip_plugins> plugin or write your own 
-disabling plugin.
-
-These modifications of disabling/re-enabling a plugin are valid for the
-full connection, not transaction! For transaction based disabling of plugins,
-use the C<reset_transaction> hook to reset the list of disabled plugins. 
-
-A small warning: the C<reset_transaction> hook is called at least three
-times: after the client sent the C<(HE|EH)LO>, every time the client
-issues a C<MAIL FROM:> and after the mail was queued (or rejected by a 
-C<data_post> hook). Don't forget it is also called after C<RSET> and 
-connection closing (e.g. after C<QUIT>).

+=head1 NAME
+
+check_earlytalker - Check that the client doesn't talk before we send the SMTP banner
+
+=head1 DESCRIPTION
+
+Checks to see if the remote host starts talking before we've issued a 2xx
+greeting.  If so, we're likely looking at a direct-to-MX spam agent which
+pipelines its entire SMTP conversation, and will happily dump an entire spam
+into our mail log even if later tests deny acceptance.
+
+Depending on configuration, clients which behave in this way are either
+immediately disconnected with a deny or denysoft code, or else are issued this
+on all mail/rcpt commands in the transaction.
+
+=head1 CONFIGURATION
+
+=over 4
+
+=item wait [integer]
+
+The number of seconds to delay the initial greeting to see if the connecting
+host speaks first.  The default is 1.  Do not select a value that is too high,
+or you may be unable to receive mail from MTAs with short SMTP connect or
+greeting timeouts -- these are known to range as low as 30 seconds, and may
+in some cases be configured lower by mailserver admins.  Network transit time
+must also be allowed for.
+
+=item action [string: deny, denysoft, log]
+
+What to do when matching an early-talker -- the options are I<deny>,
+I<denysoft> or I<log>.
+
+If I<log> is specified, the connection will be allowed to proceed as normal,
+and only a warning will be logged.
+
+The default is I<denysoft>.
+
+=item defer-reject [boolean]
+
+When an early-talker is detected, if this option is set to a true value, the
+SMTP greeting will be issued as usual, but all RCPT/MAIL commands will be
+issued a deny or denysoft (depending on the value of I<action>).  The default
+is to react at the SMTP greeting stage by issuing the apropriate response code
+and terminating the SMTP connection.
+
+=item check-at [string: connect, data]
+
+Defines when to check for early talkers, either at connect time (pre-greet pause)
+or at DATA time (pause before sending "354 go ahead").
+
+The default is I<connect>.
+
+Note that defer-reject has no meaning if check-at is I<data>.

+=head1 NAME
+
+dnsbl - handle DNS BlackList lookups
+
+=head1 DESCRIPTION
+
+Plugin that checks the IP address of the incoming connection against
+a configurable set of RBL services.
+
+=head1 Configuration files
+
+This plugin uses the following configuration files. All of these are optional.
+However, not specifying dnsbl_zones is like not using the plugin at all.
+
+=over 4
+
+=item dnsbl_zones
+
+Normal ip based dns blocking lists ("RBLs") which contain TXT records are
+specified simply as:
+
+  relays.ordb.org
+  spamsources.fabel.dk
+
+To configure RBL services which do not contain TXT records in the DNS,
+but only A records (e.g. the RBL+ at http://www.mail-abuse.org), specify your
+own error message to return in the SMTP conversation after a colon e.g.
+
+  rbl-plus.mail-abuse.org:You are listed at - http://http://www.mail-abuse.org/cgi-bin/lookup?%IP%
+
+The string %IP% will be replaced with the IP address of incoming connection.
+Thus a fully specified file could be:
+
+  sbl-xbl.spamhaus.org
+  list.dsbl.org
+  rbl-plus.mail-abuse.ja.net:Listed by rbl-plus.mail-abuse.ja.net - see <URL:http://www.mail-abuse.org/cgi-bin/lookup?%IP%>
+  relays.ordb.org
+
+=item dnsbl_allow
+
+List of allowed ip addresses that bypass RBL checking. Format is one entry per line,
+with either a full IP address or a truncated IP address with a period at the end.
+For example:
+
+  192.168.1.1
+  172.16.33.
+
+NB the environment variable RBLSMTPD is considered before this file is 
+referenced. See below.
+
+=item dnsbl_rejectmsg
+
+A textual message that is sent to the sender on an RBL failure. The TXT record
+from the RBL list is also sent, but this file can be used to indicate what
+action the sender should take.
+
+For example:
+
+   If you think you have been blocked in error, then please forward
+   this entire error message to your ISP so that they can fix their problems.
+   The next line often contains a URL that can be visited for more information.
+
+=back
+
+=head1 Environment Variables
+
+=head2 RBLSMTPD
+
+The environment variable RBLSMTPD is supported and mimics the behaviour of
+Dan Bernstein's rblsmtpd. The exception to this is the '-' char at the 
+start of RBLSMTPD which is used to force a hard error in Dan's rblsmtpd.
+NB I don't really see the benefit
+of using a soft error for a site in an RBL list. This just complicates
+things as it takes 7 days (or whatever default period) before a user
+gets an error email back. In the meantime they are complaining that their
+emails are being "lost" :(
+
+=over 4
+
+=item RBLSMTPD is set and non-empty
+
+The contents are used as the SMTP conversation error.
+Use this for forcibly blocking sites you don't like
+
+=item RBLSMTPD is set, but empty
+
+In this case no RBL checks are made.
+This can be used for local addresses.
+
+=item RBLSMTPD is not set
+
+All RBL checks will be made.
+This is the setting for remote sites that you want to check against RBL.

Subject: [PATCH 0671/1467] This fixes a really nasty bug that means that some
 (mostly spam, admittedly) mail would get missed. What happens is if you pause
 the connection (needed if you YIELD for something) then the line-reading loop
 exits, and never gets back there unless the client sends more data. If the
 client is an abuser (i.e. pipelines) then you might never get back to the
 read loop. (yes, this was a bitch to track down :-))

+If you wish to provide your own Received header line, do it here.
+
+The hook is passed the following extra parameters (beyond $self and $transaction):
+
+ - $smtp - the SMTP type used (e.g. "SMTP" or "ESMTP").
+ - $auth - the Auth header additionals.
+ - $sslinfo - information about SSL for the header.

+=head1 Introduction
+
+Plugins are the heart of qpsmtpd. The core implements only basic SMTP protocol
+functionality. No useful function can be done by qpsmtpd without loading 
+plugins.
+
+Plugins are loaded on startup where each of them register their interest in 
+various I<hooks> provided by the qpsmtpd core engine.
+
+At least one plugin B<must> allow or deny the B<RCPT> command to enable 
+receiving mail. The F<check_relay> plugin is the standard plugin for this.
+Other plugins provide extra functionality related to this; for example the
+F<require_resolvable_fromhost> plugin.
+
+=head2 Loading Plugins
+
+The list of plugins to load are configured in the I<config/plugins>
+configuration file. One plugin per line, empty lines and lines starting
+with I<#> are ignored. The order they are loaded is the same as given 
+in this config file. This is also the order the registered I<hooks>
+are run. The plugins are loaded from the F<plugins/> directory or 
+from a subdirectory of it. If a plugin should be loaded from such a 
+subdirectory, the directory must also be given, like the 
+F<virus/clamdscan> in the example below. Alternate plugin directories
+may be given in the F<config/plugin_dirs> config file, one directory
+per line, these will be searched first before using the builtin fallback
+of F<plugins/> relative to the qpsmtpd root directory. It may be 
+necessary, that the F<config/plugin_dirs> must be used (if you're using 
+F<Apache::Qpsmtpd>, for example).
+
+Some plugins may be configured by passing arguments in the F<plugins>
+config file.
+
+A plugin can be loaded two or more times with different arguments by adding
+I<:N> to the plugin filename, with I<N> being a number, usually starting at 
+I<0>. 
+
+Another method to load a plugin is to create a valid perl module, drop this
+module in perl's C<@INC> path and give the name of this module as
+plugin name. The only restriction to this is, that the module name B<must>
+contain I<::>, e.g. C<My::Plugin> would be ok, C<MyPlugin> not. Appending of
+I<:0>, I<:1>, ... does not work with module plugins.

+
+=head1 Anatomy of a plugin
+
+A plugin has at least one method, which inherits from the 
+C<Qpsmtpd::Plugin> object. The first argument for this method is always the 
+plugin object itself (and usually called C<$self>). The most simple plugin 
+has one method with a predefined name which just returns one constant.
+
+ # plugin temp_disable_connection
+ sub hook_connect {
+    return(DENYSOFT, "Sorry, server is temporarily unavailable.");
+ }
+
+While this is a valid plugin, it is not very useful except for rare 
+circumstances. So let us see what happens when a plugin is loaded.
+
+=head2 Initialisation
+
+After the plugin is loaded the C<init()> method of the plugin is called, 
+if present. The arguments passed to C<init()> are 
+
+=over 4
+
+=item $self 
+
+the current plugin object, usually called C<$self>
+
+=item $qp
+
+the Qpsmtpd object, usually called C<$qp>.
+
+=item @args
+
+the values following the plugin name in the F<plugins> config, split by 
+white space. These arguments can be used to configure the plugin with 
+default and/or static config settings, like database paths, 
+timeouts, ...
+
+=back
+
+This is mainly used for inheriting from other plugins, but may be used to do
+the same as in C<register()>.
+
+The next step is to register the hooks the plugin provides. Any method which 
+is named C<hook_$hookname> is automagically added.
+
+Plugins should be written using standard named hook subroutines. This 
+allows them to be overloaded and extended easily. Because some of the 
+callback names have characters invalid in subroutine names , they must be 
+translated. The current translation routine is C<s/\W/_/g;>. If you choose 
+not to use the default naming convention, you need to register the hooks in 
+your plugin in the C<register()> method (see below) with the 
+C<register_hook()> call on the plugin object.
+
+  sub register {
+    my ($self, $qp, @args) = @_;
+    $self->register_hook("mail", "mail_handler");
+    $self->register_hook("rcpt", "rcpt_handler");
+  }
+  sub mail_handler { ... }
+  sub rcpt_handler { ... }
+
+The C<register()> method is called last. It receives the same arguments as 
+C<init()>. There is no restriction, what you can do in C<register()>, but 
+creating database connections and reuse them later in the process may not be
+a good idea. This initialisation happens before any C<fork()> is done. 
+Therefore the file handle will be shared by all qpsmtpd processes and the 
+database will probably be confused if several different queries arrive on 
+the same file handle at the same time (and you may get the wrong answer, if
+any). This is also true for F<qpsmtpd-async> and the pperl flavours, but 
+not for F<qpsmtpd> started by (x)inetd or tcpserver. 
+
+In short: don't do it if you want to write portable plugins.
+
+=head2 Inheritance
+
+Inheriting methods from other plugins is an advanced topic. You can alter 
+arguments for the underlying plugin, prepare something for the I<real> 
+plugin or skip a hook with this. Instead of modifying C<@ISA>
+directly in your plugin, use the C<isa_plugin()> method from the 
+C<init()> subroutine.
+
+  # rcpt_ok_child
+  sub init {
+    my ($self, $qp, @args) = @_;
+    $self->isa_plugin("rcpt_ok");
+  }
+  
+  sub hook_rcpt {
+    my ($self, $transaction, $recipient) = @_;
+    # do something special here...
+    $self->SUPER::hook_rcpt($transaction, $recipient);
+  }
+
+=head2 Config files
+
+Most of the existing plugins fetch their configuration data from files in the
+F<config/> sub directory. This data is read at runtime and may be changed
+without restarting qpsmtpd. 
+B<(FIXME: caching?!)>
+The contents of the files can be fetched via
+
+  @lines = $self->qp->config("my_config");
+
+All empty lines and lines starting with C<#> are ignored.
+
+If you don't want to read your data from files, but from a database you can 
+still use this syntax and write another plugin hooking the C<config>
+hook. 
+
+=head2 Logging
+
+Log messages can be written to the log file (or STDERR if you use the 
+F<logging/warn> plugin) with 
+
+  $self->qp->log($loglevel, $logmessage);
+
+The log level is one of (from low to high priority)
+
+=over 4
+
+=item LOGDEBUG
+
+=item LOGINFO
+
+=item LOGNOTICE
+
+=item LOGWARN
+
+=item LOGERROR
+
+=item LOGCRIT
+
+=item LOGALERT
+
+=item LOGEMERG
+
+=back
+
+While debugging your plugins, you want to set the log level in the F<logging>
+config file to I<LOGDEBUG>. This will log very much data. To restrict this 
+output just to the plugin you are debugging, you can use the following plugin: 
+
+=cut
+
+FIXME: Test if this really works as inteded ;-)
+
+=pod
+
+ # logging/debug_plugin - just show LOGDEBUG messages of one plugin
+ # Usage: 
+ #  logging/debug_plugin my_plugin LOGLEVEL
+ #
+ #  LOGLEVEL is the log level for all other log messages
+ use Qpsmtpd::Constants;
+ 
+ sub register {
+   my ($self, $qp, $plugin, $loglevel) = @_;
+   die "no plugin name given"
+     unless $plugin;
+   $loglevel = "LOGWARN"
+     unless defined $loglevel;
+   $self->{_plugin} = $plugin;
+   $self->{_level}  = Qpsmtpd::Constants::log_level($loglevel);
+   $self->{_level}  = LOGWARN 
+     unless defined $self->{_level};
+ }
+ 
+ sub hook_logging {
+   my ($self, $transaction, $trace, $hook, $plugin, @log) = @_;
+   return(OK) # drop these lines
+     if $plugin ne $self->{_plugin} and $trace > $self->{_level};
+   return(DECLINED);
+ }
+
+The above plugin should be loaded before the default logging plugin, which 
+logs with I<LOGDEBUG>. The plugin name must be the one returned by the 
+C<plugin_name()> method of the debugged plugin. This is probably not 
+the same as the name of the plugin (i.e. not the same you write in the 
+F<plugins> config file). In doubt: take a look in the log file for lines 
+like C<queue::qmail_2dqueue hooking queue> (here: F<queue/qmail-queue> 
+=E<gt> F<queue::qmail_2dqueue>).
+
+=head2 Information about the current plugin
+
+Each plugin inherits the public methods from C<Qpsmtpd::Plugin>. 
+
+=over 4
+
+=item plugin_name()
+
+Returns the name of the currently running plugin
+
+=item hook_name()
+
+Returns the name of the running hook
+
+=item auth_user()
+
+Returns the name of the user the client is authed as (if authentication is 
+used, of course)
+
+=item auth_mechanism()
+
+Returns the auth mechanism if authentication is used
+
+=item connection()
+
+Returns the C<Qpsmtpd::Connection> object associated with the current 
+connection
+
+=item transaction()
+
+Returns the C<Qpsmtpd::Transaction> object associated with the current 
+transaction
+
+=back
+
+=head2 Temporary Files
+
+The temporary file and directory functions can be used for plugin specific 
+workfiles and will automatically be deleted at the end of the current 
+transaction.
+
+=over 4
+
+=item temp_file()
+
+Returns a unique name of a file located in the default spool directory, 
+but does not open that file (i.e. it is the name not a file handle).
+
+=item temp_dir()
+
+Returns the name of a unique directory located in the default spool 
+directory, after creating the directory with 0700 rights. If you need a 
+directory with different rights (say for an antivirus daemon), you will
+need to use the base function C<$self-E<gt>qp-E<gt>temp_dir()>, which takes a 
+single parameter for the permissions requested (see L<mkdir> for details). 
+A directory created like this will not be deleted when the transaction 
+is ended.
+
+=item spool_dir()
+
+Returns the configured system-wide spool directory.
+
+=back
+
+
+=head2 Connection and Transaction Notes
+
+Both may be used to share notes across plugins and/or hooks. The only real
+difference is their life time. The connection notes start when a new 
+connection is made and end, when the connection ends. This can, for example,
+be used to count the number of none SMTP commands. The plugin which uses 
+this is the F<count_unrecognized_commands> plugin from the qpsmtpd core
+distribution.
+
+The transaction note starts after the B<MAIL FROM: > command and are just 
+valid for the current transaction, see below in the I<reset_transaction>
+hook when the transaction ends.
+
+
+=head1 Return codes
+
+Each plugin must return an allowed constant for the hook and (usually)
+optionally a ``message'' for the client.
+Generally all plugins for a hook are processed until one returns 
+something other than I<DECLINED>.
+
+Plugins are run in the order they are listed in the F<plugins> 
+configuration file.
+
+The return constants are defined in C<Qpsmtpd::Constants> and have
+the following meanings:
+
+=over 4
+
+=item DECLINED
+
+Plugin declined work; proceed as usual. This return code is I<always allowed>
+unless noted otherwise.
+
+=item OK
+
+Action allowed.
+
+=item DENY
+
+Action denied.
+
+=item DENYSOFT
+
+Action denied; return a temporary rejection code (say B<450> instead 
+of B<550>).
+
+=item DENY_DISCONNECT
+
+Action denied; return a permanent rejection code and disconnect the client. 
+Use this for "rude" clients. Note that you're not supposed to do this 
+according to the SMTP specs, but bad clients don't listen sometimes.
+
+=item DENYSOFT_DISCONNECT
+
+Action denied; return a temporary rejection code and disconnect the client. 
+See note above about SMTP specs.
+
+=item DONE
+
+Finishing processing of the request. Usually used when the plugin sent the 
+response to the client.
+
+=back
+
+The I<YIELD> constant is not mentioned here, because it is not used by
+plugins directly.
+
+=head1 SMTP hooks
+
+This section covers the hooks, which are run in a normal SMTP connection. 
+The order of these hooks is like you will (probably) see them, while a mail
+is received. 
+
+Every hook receives a C<Qpsmtpd::Plugin> object of the currently 
+running plugin as the first argument. A C<Qpsmtpd::Transaction> object is 
+the second argument of the current transaction in the most hooks, exceptions 
+are noted in the description of the hook. If you need examples how the 
+hook can be used, see the source of the plugins, which are given as 
+example plugins.
+
+=head2 hook_pre_connection
+
+Called by a controlling process (e.g. forkserver or prefork) after accepting 
+the remote server, but before beginning a new instance (or handing the 
+connection to the worker process).
+
+Useful for load-management and rereading large config files at some
+frequency less than once per session.
+
+This hook only works in the F<qpsmtpd-forkserver> and F<qpsmtpd-prefork>
+flavours. 
+
+=cut 
+
+NOT FOR: -async, apache, -server and inetd/pperl
+
+=pod
+
+B<NOTE:> You should not use this hook to do major work and / or use lookup 
+methods which (I<may>) take some time, like DNS lookups. This will slow down
+B<all> incoming connections, no other connection will be accepted while this
+hook is running!
+
+Arguments this hook receives are:
+
+  my ($self,$transaction,%args) = @_;
+  # %args is:
+  # %args = ( remote_ip    => inet_ntoa($iaddr),
+  #           remote_port  => $port,
+  #           local_ip     => inet_ntoa($laddr),
+  #           local_port   => $lport,
+  #           max_conn_ip  => $MAXCONNIP,
+  #           child_addrs  => [values %childstatus],
+  #         );
+
+B<NOTE:> the C<$transaction> is of course C<undef> at this time.
+
+Allowed return codes are

+=over 4
+
+=item DENY / DENY_DISCONNECT
+
+returns a B<550> to the client and ends the connection
+
+=item DENYSOFT / DENYSOFT_DISCONNECT
+

+
+It is called at the start of a connection before the greeting is sent to 
+the connecting client.
+
+Arguments for this hook are

+=back
+
+Arguments of this hook are
+
+  my ($self, $transaction, $host) = @_;
+  # $host: the name the client sent in the 
+  # (EH|HE)LO line
+
+B<NOTE:> C<$transaction> is C<undef> at this point.
+
+=head2 hook_mail_pre
+
+After the B<MAIL FROM: > line sent by the client is broken into 
+pieces by the C<hook_mail_parse()>, this hook recieves the results.
+This hook may be used to pre-accept adresses without the surrounding 
+I<E<lt>E<gt>> (by adding them) or addresses like 
+I<E<lt>user@example.com.E<gt>> or I<E<lt>user@example.com E<gt>> by 
+removing the trailing I<"."> / C<" ">.
+
+Expected return values are I<OK> and an address which must be parseable
+by C<Qpsmtpd::Address-E<gt>parse()> on success or any other constant to
+indicate failure.
+
+Arguments are 
+
+  my ($self, $transaction, $addr) = @_;
+
+=head2 hook_mail
+
+Called right after the envelope sender line is parsed (the B<MAIL FROM: >
+command). The plugin gets passed a C<Qpsmtpd::Address> object, which means 
+the parsing and verifying the syntax of the address (and just the syntax, 
+no other checks) is already done. Default is to allow the sender address. 
+The remaining arguments are the extensions defined in RFC 1869 (if sent by 
+the client).
+
+B<NOTE:> According to the SMTP protocol, you can not reject an invalid
+sender until after the B<RCPT> stage (except for protocol errors, i.e.
+syntax errors in address). So store it in an C<$transaction-E<gt>note()> and 
+process it later in an rcpt hook.
+
+Allowed return codes are

+
+=head2 hook_rcpt_pre
+
+See C<hook_mail_pre>, s/MAIL FROM:/RCPT TO:/.
+
+=head2 hook_rcpt
+
+This hook is called after the client sent an I<RCPT TO: > command (after 
+parsing the line). The given argument is parsed by C<Qpsmtpd::Address>, 
+then this hook is called. Default is to deny the mail with a soft error 
+code. The remaining arguments are the extensions defined in RFC 1869
+(if sent by the client).

+
+=head2 hook_data
+
+After the client sent the B<DATA> command, before any data of the message
+was sent, this hook is called. 
+
+B<NOTE:> This hook, like B<EHLO>, B<VRFY>, B<QUIT>, B<NOOP>, is an 
+endpoint of a pipelined command group (see RFC 1854) and may be used to 
+detect ``early talkers''. Since svn revision 758 the F<check_earlytalker>
+plugin may be configured to check at this hook for ``early talkers''.

+extension (RFC 1869, 1830/3030) ... a plugin for this exists at

+without notice (without a B<QUIT>). This hook is not called if the qpsmtpd

+=head1 Parsing Hooks
+
+Before the line from the client is parsed by 
+C<Qpsmtpd::Command-E<gt>parse()> with the built in parser, these hooks 
+are called. They can be used to supply a parsing function for the line,
+which will be used instead of the built in parser.
+
+The hook must return two arguments, the first is (currently) ignored,
+the second argument must be a (CODE) reference to a sub routine. This sub 
+routine receives three arguments:
+
+=over 4
+
+=item $self
+
+the plugin object
+
+=item $cmd
+
+the command (i.e. the first word of the line) sent by the client
+
+=item $line
+
+the line sent by the client without the first word
+
+=back
+
+Expected return values from this sub are I<DENY> and a reason which is 
+sent to the client or I<OK> and the C<$line> broken into pieces according
+to the syntax rules for the command.
+
+B<NOTE: ignore the example from C<Qpsmtpd::Command>, the C<unrecognized_command_parse> hook was never implemented,...>
+
+=head2 hook_helo_parse / hook_ehlo_parse
+
+The provided sub routine must return two or more values. The first is 
+discarded, the second is the hostname (sent by the client as argument 
+to the B<HELO> / B<EHLO> command). All other values are passed to the 
+helo / ehlo hook. This hook may be used to change the hostname the client
+sent... not recommended, but if your local policy says only to accept
+I<HELO> hosts with FQDNs and you have a legal client which can not be 
+changed to send his FQDN, this is the right place.
+
+=head2 hook_mail_parse / hook_rcpt_parse
+
+The provided sub routine must return two or more values. The first is 
+either I<OK> to indicate that parsing of the line was successfull
+or anything else to bail out with I<501 Syntax error in command>. In
+case of failure the second argument is used as the error message for the 
+client.
+
+If parsing was successfull, the second argument is the sender's / 
+recipient's address (this may be without the surrounding I<E<lt>> and 
+I<E<gt>>, don't add them here, use the C<hook_mail_pre()> / 
+C<hook_rcpt_pre()> methods for this). All other arguments are 
+sent to the C<mail / rcpt> hook as B<MAIL> / B<RCPT> parameters (see 
+RFC 1869 I<SMTP Service Extensions> for more info). Note that 
+the mail and rcpt hooks expect a list of key/value pairs as the 
+last arguments.

+=head1 Writing your own plugins
+
+This is a walk through a new queue plugin, which queues the mail to a (remote)
+QMQP-Server.
+
+First step is to pull in the necessary modules
+
+ use IO::Socket;
+ use Text::Netstring qw( netstring_encode 
+                         netstring_decode 
+                         netstring_verify 
+                         netstring_read );
+
+We know, we need a server to send the mails to. This will be the same 
+for every mail, so we can use arguments to the plugin to configure this 
+server (and port).
+
+Inserting this static config is done in C<register()>:
+
+  sub register {
+    my ($self, $qp, @args) = @_;
+  
+    die "No QMQP server specified in qmqp-forward config"
+      unless @args;

+    $self->{_qmqp_timeout} = 120;
+  
+    if ($args[0] =~ /^([\.\w_-]+)$/) {
+      $self->{_qmqp_server} = $1;
+    }
+    else {
+      die "Bad data in qmqp server: $args[0]";
+    }
+  
+    $self->{_qmqp_port} = 628;
+    if (@args > 1 and $args[1] =~ /^(\d+)$/) {
+      $self->{_qmqp_port} = $1;
+    }
+  
+    $self->log(LOGWARN, "WARNING: Ignoring additional arguments.") 
+      if (@args > 2);

+
+The client starts with a safe 8-bit text message. It encodes the message 
+as the byte string C<firstline\012secondline\012 ... \012lastline>. (The
+last line is usually, but not necessarily, empty.) The client then encodes
+this byte string as a netstring. The client also encodes the envelope 
+sender address as a netstring, and encodes each envelope recipient address
+as a netstring.
+
+The client concatenates all these netstrings, encodes the concatenation 
+as a netstring, and sends the result. 
+
+(from L<http://cr.yp.to/proto/qmqp.html>)

+
+The first idea is to build the package we send, in the order described 
+in the paragraph above:
+
+  my $message = $transaction->header->as_string;
+  $transaction->body_resetpos;
+  while (my $line = $transaction->body_getline) {
+    $message .= $line;
+  }
+  $message  = netstring_encode($message);
+  $message .= netstring_encode($transaction->sender->address);
+  for ($transaction->recipients) {
+    push @rcpt, $_->address;
+  }
+  $message .= join "", netstring_encode(@rcpt);
+  print $sock netstring_encode($message)
+    or do { 
+      my $err = $!;
+      $self->_disconnect($sock);
+      return(DECLINED, "Failed to print to socket: $err");
+    };
+
+This would mean, we have to hold the full message in memory... Not good 
+for large messages, and probably even slower (for large messages).
+
+Luckily it's easy to build a netstring without the help of the
+C<Text::Netstring> module if you know the size of the string (for more
+info about netstrings see L<http://cr.yp.to/proto/netstrings.txt>).
+
+We start with the sender and recipient addresses:
+
+  my ($addrs, $headers, @rcpt);
+  $addrs = netstring_encode($transaction->sender->address);
+  for ($transaction->recipients) {
+    push @rcpt, $_->address;
+  }
+  $addrs .= join "", netstring_encode(@rcpt);
+
+Ok, we got the sender and the recipients, now let's see what size the
+message is.
+
+  $headers   = $transaction->header->as_string;
+  my $msglen = length($headers) + $transaction->body_length;
+
+We've got everything we need. Now build the netstrings for the full package
+and the message.
+
+First the beginning of the netstring of the full package 
+
+  # (+ 2: the ":" and "," of the message's netstring)
+  print $sock ($msglen + length($msglen) + 2 + length($addrs))
+               .":"
+               ."$msglen:$headers" ### beginning of messages netstring
+    or do { 
+      my $err = $!;
+      $self->_disconnect($sock);
+      return(DECLINED, 
+             "Failed to print to socket: $err");
+    };
+
+Go to beginning of the body
+
+  $transaction->body_resetpos;
+
+If the message is spooled to disk, read the message in
+blocks and write them to the server
+
+  if ($transaction->body_fh) {
+    my $buff;
+    my $size = read $transaction->body_fh, $buff, 4096;
+    unless (defined $size) {
+      my $err = $!;
+      $self->_disconnect($sock);

+               "Failed to read from body_fh: $err");
+      }
+    }
+  }
+
+Else we have to read it line by line ...
+
+  else { 
+    while (my $line = $transaction->body_getline) {
+      print $sock $line
+        or do { 
+          my $err = $!;
+          $self->_disconnect($sock);
+          return(DECLINED, "Failed to print to socket: $err");
+        };
+    }
+  }
+
+Message is at the server, now finish the package.
+
+  print $sock ","    # end of messages netstring
+             .$addrs # sender + recpients
+             .","    # end of netstring of

+=item *
+
+(continued from L<http://cr.yp.to/proto/qmqp.html>:)
+
+The server's response is a nonempty string of 8-bit bytes, encoded as a 
+netstring.
+  
+The first byte of the string is either K, Z, or D. K means that the 
+message has been accepted for delivery to all envelope recipients. This 
+is morally equivalent to the 250 response to DATA in SMTP; it is subject 
+to the reliability requirements of RFC 1123, section 5.3.3. Z means 
+temporary failure; the client should try again later. D means permanent 
+failure.
+   
+Note that there is only one response for the entire message; the server 
+cannot accept some recipients while rejecting others.
+
+=back
+
+
+    my $answer = netstring_read($sock);
+    $self->_disconnect($sock);
+

+    }
+
+If this is the only F<queue/*> plugin, the client will get a 451 temp error:

+
+If you want to make the client think a message has been regularily accepted,

+=head1 NAME
+
+uribl - URIBL blocking plugin for qpsmtpd
+
+$Id$
+
+=head1 DESCRIPTION
+
+This plugin implements DNSBL lookups for URIs found in spam, such as that
+implemented by SURBL (see E<lt>http://surbl.org/E<gt>).  Incoming messages are
+scanned for URIs, which are then checked against one or more URIBLs in a
+fashion similar to DNSBL systems.
+
+=head1 CONFIGURATION
+
+To enable the plugin, add it to I<~qpsmtpd/config/plugins>.  The list of
+URIBLs to check should be placed in I<uribl_zones> in the config directory
+(typically I<~qpsmtpd/config>).
+
+The format of the I<uribl_zones> file is a list of URIBL DNS zones, one per
+line, consisting of one or more columns separated by whitespace.  The first
+column (the only mandatoy one) should consist of the URIBL zone.
+
+The second column may contain a comma-delimited list of integers selecting
+mask values to be applied to the A record(s) returned from a URIBL.  This
+enables the use of composite DNSBLs, such as multi.surbl.org, where several
+lists are combined so they may be accessed with a single query; any returns
+are checked against the mask of lists you're interested in.  If unspecified,
+or if a negative number is given, all lists in a composite URIBL will be
+checked.  URIBL operators prefer that you use the composite lists to reduce
+their own query load, and it's more efficient for qpsmtpd as well.
+
+The third column specifies an action, which overrides the default action
+configured with the I<action> setting discussed below.
+
+For example:
+
+=over 4
+
+    multi.surbl.org    2,8    deny
+    ob.surbl.org    1    add-header
+
+=back
+
+You may specify the following config option(s) in the I<qpsmtpd/config> file:
+
+=over 4
+
+=item action
+
+Specifies what to do when a URI is matched in a URIBL.  Available options are
+I<add-header> (the default) I<deny> and I<denysoft>.  If set to add-header, an
+X-URIBL-Match: header will be added explaining the URIBL entry found.  If set
+to 'deny,' the delivery will be declined with a hard failure.  If set to
+denysoft, the delivery will be soft failed (this is probably not a good idea.)
+
+=item timeout
+
+Timeout for DNS requests, in seconds.  The default is 30 seconds.  DNS
+requests are issued asynchronously and in parallel for all hosts found
+in URIs in the mail; the same timeout will apply to each; see the
+Net::DNS documentation for details.
+
+=item scan-headers
+
+If set true, any headers found in the URIs will be checked as well.  Disabled
+by default.
+
+=back
+
+=head1 CAUTIONS
+
+When used in I<deny> or I<denysoft> mode, a URIBL check can block not
+only the original spam containing a listed URI, but mail unintentionally
+carrying that URI, such as forwarded complaints.  The uribl checks should
+only be used in these modes if you know what you're doing.
+
+The URI scanner used by the uribl plugin is quite aggressive, and attempts to
+detect all forms of URIs supported by typical MUAs (even those that lack a
+protocol specification, for example.)  However, it does not attempt to detect
+URIs that have been mangled beyond programmatic reconstruction.  Even so, it
+may issue spurious lookups on unintended URIs, especially those in non-text
+sections of the mail.
+
+=head1 COPYRIGHT
+
+uribl is copyright 2004-2007 by Devin Carraway E<lt>qpsmtpd@devin.comE<gt>.  It
+may be used and redistributed under the same terms as qpsmtpd itself.

+=head1 NAME
+
+help - default help plugin for qpsmtpd
+
+=head1 DESCRIPTION
+
+The B<help> plugin gives the answers for the help command. It can be configured
+to return C<502 Not implemented>.
+
+Without any arguments, the C<help_dir> is set to F<./help/>.
+
+=head1 OPTIONS
+
+=over 4
+
+=item not_implemented (1|0)
+
+If this option is set (and the next argument is true), the plugin answers, 
+that the B<HELP> command is not implemented
+
+=item help_dir /path/to/help/files/
+
+When a client requests help for C<COMMAND> the file F</path/to/help/files/ 
+. lc(COMMAND)> is dumped to the client if it exists.
+
+=item COMMAND HELPFILE
+
+Any other argument pair is treated as command / help file pair. The file is 
+expexted in the F<help/> sub directory. If the client calls C<HELP COMMAND>
+the contents of HELPFILE are dumped to him.
+
+=back
+
+=head1 NOTES
+
+The hard coded F<help/> path should be changed.

 =head1 BUGS
 
-Currently the F<check_early_talker> plugin will not work because it
-relies on being able to do C<select()> on F<STDIN> which does not
-work here. It should be possible with the next release of mod_perl
-to do a C<poll()> on the socket though, so we can hopefully get
-that working in the future.
+Probably a few. Make sure you test your plugins carefully.
 
-Other operations that perform directly on the STDIN/STDOUT filehandles
-will not work.
+The Apache scoreboard (/server-status/) mostly works and shows
+connections, but could do with some enhancements specific to SMTP.

Subject: [PATCH 0793/1467] New fix for the problem of End-of-data splitted
 across packets. Previous fix does not work for other cases, for example:
 packet ends with CRLFdot, next packet starts with CRLF.

Danga::Client will send now full text lines to the callback.

 forkserver          - use user/group switching from forkserver to support
 secondary 	   groups (needed with plugins/queue/postfix-queue)

+Pluging that checks the host part of the sender's address against a

+
+=head1 CONFIGURATION
+
+This plugin reads the lists to use from the rhsbl_zones configuration
+file. Normal domain based dns blocking lists ("RBLs") which contain TXT
+records are specified simply as:
+
+  dsn.rfc-ignorant.org
+
+To configure RBL services which do not contain TXT records in the DNS,
+but only A records, specify, after a whitespace, your own error message
+to return in the SMTP conversation e.g.
+
+  abuse.rfc-ignorant.org does not support abuse@domain

+=head1 NAME
+
+dns_whitelist_soft - dns-based whitelist override for other qpsmtpd plugins
+
+=head1 DESCRIPTION
+
+The dns_whitelist_soft plugin allows selected host to be whitelisted as
+exceptions to later plugin processing.  It is most suitable for multisite
+installations, so that the whitelist is stored in one location and available
+from all.
+
+=head1 CONFIGURATION
+
+To enable the plugin, add it to the ~qpsmtpd/config/plugins file as usual.
+It should precede any plugins whose rejections you wish to override.  You may
+have to alter those plugins to check the appropriate notes field.
+
+Several configuration files are supported, corresponding to different
+parts of the SMTP conversation:
+
+=over 4
+
+=item whitelist_zones
+
+Any IP address listed in the whitelist_zones file is queried using
+the connecting MTA's IP address.  Any A or TXT answer means that the
+remote HOST address can be selectively exempted at other stages by plugins
+testing for a 'whitelisthost' connection note.
+
+=back
+
+NOTE: in contrast to the non-async version, the other 'connect' hooks
+fired after the 'connect' hook of this plugin will see the 'whitelisthost'
+connection note, if set by this plugin.

+
+=head1 DESCRIPTION
+
+Pluging that checks the host part of the sender's address against a
+configurable set of RBL services.
+
+=head1 CONFIGURATION
+
+This plugin reads the lists to use from the rhsbl_zones configuration
+file. Normal domain based dns blocking lists ("RBLs") which contain TXT
+records are specified simply as:
+
+  dsn.rfc-ignorant.org
+
+To configure RBL services which do not contain TXT records in the DNS,
+but only A records, specify, after a whitespace, your own error message
+to return in the SMTP conversation e.g.
+
+  abuse.rfc-ignorant.org does not support abuse@domain

+
+uribl - URIBL blocking plugin for qpsmtpd
+
+=head1 DESCRIPTION
+
+This plugin implements DNSBL lookups for URIs found in spam, such as that
+implemented by SURBL (see E<lt>http://surbl.org/E<gt>).  Incoming messages are
+scanned for URIs, which are then checked against one or more URIBLs in a
+fashion similar to DNSBL systems.
+
+=head1 CONFIGURATION
+
+See the documentation of the non-async version. The timeout config option is
+ignored, the ParaDNS timeout is used instead.

 =head1 NAME
 
 queue/maildir
 
 =head1 DESCRIPTION
 
-This plugin delivers mails to a maildir spool. 
+This plugin delivers mails to a maildir spool.
 
 =head1 CONFIG
 
 It takes one required parameter, the location of the maildir.
 
+A second optional parameter delivers the mail into a sub directory named by 
+the recipient of the mail B<for each recipient>. Some substituions take place.
+Before replacing the parts descibed below, any character of the recipient 
+address, which is not one of C<-A-Za-z0-9+_.,@=> is set to a C<_>.
+
+If a third parameter is given, it will be used as octal (!) permisson of the
+newly created files and directories, any execute bits will be stripped for 
+files: Use C<770> to create group writable directories and files with mode 
+C<0660>.
+
+=head2 Maildir spool directory substitutions
+
+=over 4
+
+=item %l
+
+Replaced by the local part of the address (i.e. the username)
+
+=item %d
+
+Replaced by the domain part of the address (i.e. the domain name)
+
+=item %u
+
+Replaced by the full address.
+
+=cut 
+
+# =item %%
+# 
+# Replaced by a single percent sign (%)
+# 
+# =cut
+
+=back
+
+Examples: if the plugin is loaded with the parameters
+
+  queue/maildir /var/spool/qpdeliver %d/%l
+
+and the recipient is C<user@example.com> the mails will be written to
+the C<new> sub directory of C</var/spool/qpdeliver/example.com/user/>.
+
+With 
+
+  queue/maildir /var/spool/qpdeliver %u
+
+and a recipient of C<user@example.org> the mail goes to
+C</var/spool/qpdeliver/user@example.org>.
+
+=head1 NOTES
+
+Names of the substitution parameters and the replaced charachters are the same
+L<spamd(8)> supports, for more info see the C<--virtual-config-dir> 
+option of L<spamd(8)>.
+
+When called with more than one parameter, this plugin is probably not usable
+with qpsmtpd-async.
+
+With the the second parameter being C<%d> it will still deliver one message 
+for each recipient: With the two recpients C<user@example.org> and 
+C<user2@example.org> you get two messages in the C<example.org/> directory.

Subject: [PATCH 0848/1467] Inside the main loop skip the sleep when children
 have exited. Instead, proceed directly to the pool adjustment. While at it,
 simplify processing by moving the update of shared memory from the SIGCHLD
 handler to the main loop.

Someone needs to remember to run `make manifest` more often, to catch
things added and deleted.  Most of this change is just reordering to be
alphabetical, but it does remove the old select-server stuff, adds one
new test file and a couple of new plugins.

Subject: [PATCH 0873/1467] Don't do printf interpolation on config('me')

The code feeds the results of $session->config('me') to
sprintf as part of the format string. In practice, this is
probably not a problem since hostnames don't contain percent
signs. However, it triggers a taint warning in perl 5.10,
making cram-md5 auth unusable.

This patch rewrites the sprintf to insert the 'me' value
using a %s format specifier.

Subject: [PATCH 0874/1467] PATCH: Log the name of plugins generating fatal
 errors

   I've got many non-standard plugins and for a given
  fatal error it is non-trivial to determine which of
  them was to blame.

   Perhaps this patch would be useful?  (Against SVN,
 not git, but I think that shouldn't matter too much..)

-=head1 General return codes
-
-Each plugin must return an allowed constant for the hook and (usually)
-optionally a "message".
-
-Generally all plugins for a hook are processed until one returns
-something other than "DECLINED".
-
-Plugins are run in the order they are listed in the "plugins"
-configuration.
-
-=over 4
-
-=item OK
-
-Action allowed
-
-=item DENY
-
-Action denied
-
-=item DENYSOFT
-
-Action denied; return a temporary rejection code (say 450 instead of 550).
-
-=item DENY_DISCONNECT
-
-Action denied; return a permanent rejection code and disconnect the client.
-Use this for "rude" clients. Note that you're not supposed to do this
-according to the SMTP specs, but bad clients don't listen sometimes.
-
-=item DENYSOFT_DISCONNECT
-
-Action denied; return a temporary rejection code and disconnect the client.
-
-=item DECLINED
-
-Plugin declined work; proceed as usual.  This return code is _always_
-_allowed_ unless noted otherwise.
-
-=item DONE
-
-Finishing processing of the request.  Usually used when the plugin
-sent the response to the client.
-
-=back
-
-See more detailed description for each hook below.
-
-=head1 Hooks
-
-=head2 pre-connection
-
-Called by a controlling process (e.g. forkserver or Apache::Qpsmtpd) after
-accepting the remote server, but before beginning a new instance.  Useful for
-load-management and rereading large config files at some frequency less than
-once per session.  The hook doesn't have a predefined additional input value,
-but one can be passed as a hash of name/value pairs.
-
-=head2 post-connection
-
-Like pre-connection only it can be called after an instance has been
-completely finished (e.g. after the child process has ended in forkserver).  
-The hook doesn't have a predefined additional input value, but one can be
-passed as a hash of name/value pairs.
-
-
-=head2 connect
-
-Allowed return codes:
-
-  OK       - Stop processing plugins, give the default response
-  DECLINED - Process the next plugin
-  DONE     - Stop processing plugins and don't give the default response
-  DENY     - Return hard failure code and disconnect
-  DENYSOFT - Return soft failure code and disconnect
-
-Note: DENY_DISCONNECT and DENYSOFT_DISCONNECT are not supported here due to
-them having no meaning beyond what DENY and DENYSOFT already do.

-
-Called on "helo" from the client.

-  DENY     - Return a 550 code
-  DENYSOFT - Return a 450 code
-  DENY_DISCONNECT & DENYSOFT_DISCONNECT - as above but with disconnect

-  DECLINED - Qpsmtpd will send the standard HELO message
-
-
-=head2 mail
-
-Called right after the envelope sender address is passed.  The plugin
-gets passed a Mail::Address object.  Default is to allow the
-recipient.
-
-Allowed return codes
-
-  OK              - sender allowed
-  DENY            - Return a hard failure code
-  DENYSOFT        - Return a soft failure code
-  DENY_DISCONNECT & DENYSOFT_DISCONNECT - as above but with disconnect
-  DONE            - skip further processing
-
-
-=head2 rcpt
-
-Hook for the "rcpt" command.  Defaults to deny the mail with a soft
-error code.
-
-Allowed return codes
-
-  OK              - recipient allowed
-  DENY            - Return a hard failure code

-  DENY_DISCONNECT & DENYSOFT_DISCONNECT - as above but with disconnect
-  DONE            - skip further processing
-
-
-=head2 data
-
-Hook for the "data" command.  Defaults to '354, "go ahead"'.
-
-  DENY     - Return a hard failure code
-  DENYSOFT - Return a soft failure code
-  DENY_DISCONNECT & DENYSOFT_DISCONNECT - as above but with disconnect
-  DONE     - Plugin took care of receiving data and calling the queue (not
-             recommended)
-
-
-=head2 data_headers_end
-
-Hook fires after all header lines of the message data has been received.
-Defaults to doing nothing, just continue processing.  At this step,
-the sender is not waiting for a reply, but we can try and prevent him from
-sending the entire message by disconnecting immediately. (Although it is
-likely the packets are already in flight due to buffering and pipelining).
-
-BE CAREFUL!  If you drop the connection legal MTAs will retry again and again,
-spammers will probably not.  This is not RFC compliant and can lead to
-an unpredictable mess. Use with caution.
-
-Allowed return codes:
-
-  DENY_DISCONNECT     - Return '554 Message denied' and disconnect
-  DENYSOFT_DISCONNECT - Return '421 Message denied temporarily' and disconnect
-  DECLINED            - Do nothing
-
-=head2 data_post
-
-Hook after receiving all data; just before the message is queued.
-
-  DENY     - Return a hard failure code
-  DENYSOFT - Return a soft failure code
-  DENY_DISCONNECT & DENYSOFT_DISCONNECT - as above but with disconnect
-  DONE     - skip further processing (message will not be queued)
-
-All other codes and the message will be queued normally
-
-
-=head2 queue
-
-Called on completion of the DATA command, after the data_post hook.

-   OK       - Return success message 
-   DENY     - Return hard failure code
-   DENYSOFT - Return soft failure code
-
-Any other code will return a soft failure code.
-
-
-=head2 quit
-
-Called on the "quit" command.
-
-Allowed return codes:
-
-  DONE 
-
-Works like the "connect" hook.
-
-
-=head2 unrecognized_command
-
-Called when we get a command that isn't recognized.
-
-  DENY_DISCONNECT - Return 521 and disconnect the client
-  DENY            - Return 500
-  DONE            - Qpsmtpd won't do anything; the plugin responded 
-  Anything else   - Return '500 Unrecognized command'
-
-=head2 disconnect
-
-Called just before we shutdown a connection.
-
-The return code is ignored.  If a plugin returns anything but DECLINED
-the following plugins will not be run (like with all other hooks).
-
-=head2 deny
-
-Called when another hook returns DENY or DENYSOFT.  First parameter is
-the previous hook return code; the second parameter the message the
-hook returned. 
-
-Returning DONE or OK will stop the next deny hook from being run.
-DECLINED will make qpsmtpd run the remaining configured deny hooks.
-
-=head2 vrfy
-
-Hook for the "VRFY" command.  Defaults to returning a message telling
-the user to just try sending the message.
-
-Allowed return codes:
-
-   OK       - Recipient Exists
-   DENY     - Return a hard failure code
-   DONE     - Return nothing and move on
-   Anything Else - Return a 252
-
-=head1 Return Values and Notes
-
-Insert stuff here about how:
-
-    - if we're in a transaction, the results of a callback are stored
-in
-    $self->transaction->notes( $code->{name})->{"hook_$hook"}->{return}
-
-    - if we're in a connection, store things in the connection notes instead.
-
-=head2 received_line
-
-If you wish to provide your own Received header line, do it here.
-
-The hook is passed the following extra parameters (beyond $self and $transaction):
-
- - $smtp - the SMTP type used (e.g. "SMTP" or "ESMTP").
- - $auth - the Auth header additionals.
- - $sslinfo - information about SSL for the header.
-
-You're free to use or discard any of the above.
-
-Allowed return codes:
-
-  OK, $string   - use this string for the Received header.
-  Anything Else - use the standard Received header.
-
-
-
-=head1 Include Files
-
-(put more about how the $Include stuff works here)
-
-With the $Include stuff you order using the filename of the plugin.d
-file. So if you have a plugin called xyz but want it to come early on,
-you call it's config file 00_xyz, but that file still refers to the
-plugin called xyz.
-
-=head1 Temporary Files
-
-The temporary file and directory functions can be used for plugin specific
-workfiles and will automatically be deleted at the end of the current
-transaction.
-
-=over 4
-
-=item temp_file()
-
-Returns a unique name of a file located in the default spool directory, but
-does not open that file (i.e. it is the name not a file handle).
-
-=item temp_dir()
-
-Returns the name of a unique directory located in the default spool
-directory, after creating the directory with 0700 rights.  If you need a
-directory with different rights (say for an antivirus daemon), you will
-need to use the base function $self->qp->temp_dir() which takes a single
-parameter for the permissions requested (see L<mkdir> for details).  A
-directory created like this will B<not> be deleted when the transaction is
-ended.
-
-=item spool_dir()
-
-Returns the configured system-wide spool directory.
-
-=back
-
-=head1 Naming Conventions
-
-Plugins should be written using standard named hook subroutines.  This
-allows them to be overloaded and extended easily.
-
-Because some of our callback names have characters invalid in
-subroutine names, they must be translated.  The current translation
-routine is: C< s/\W/_/g; >

-=head1 Register
-
-If you choose not to use the default naming convention, you need to
-register the hooks in your plugin.  You do this with the C< register >
-method call on the plugin object.
-
-  sub register {
-    my ($self, $qp) = @_;

-    $self->register_hook('mail', 'mail_handler');

-    $self->register_hook('disconnect', 'disconnect_handler');
-  }
-
-  sub mail_handler { ... }
-  sub rcpt_handler { ... }
-  sub disconnect_handler { ... }
-
-A single plugin can register as many hooks as it wants, and can
-register a hook multiple times.
-
-The C< register > method is also often used for initialization and
-reading configuration.
-
-=head1 Init
-
-The 'init' method is the first method called after a plugin is
-loaded.  It's mostly for inheritance, below.
-
-=head1 Inheritance
-
-Instead of modifying @ISA directly in your plugin, use the 
-C< isa_plugin > method from the init subroutine.

-  # rcpt_ok_child
-  sub init {
-    my ($self, $qp) = @_;
-    $self->isa_plugin('rcpt_ok');

+=head1 Developing Qpsmtpd
+
+=head2 Mailing List
+
+All qpsmtpd development happens on the qpsmtpd mailing list.
+
+Subscribe by sending mail to qpsmtpd-subscribe@perl.org
+
+=head2 Git
+
+We use git for version control.
+
+Ask owns the master repository at git://github.com/abh/qpsmtpd.git
+
+We suggest using github to host your repository -- it makes your
+changes easily accessible for pulling into the master.  After you
+create a github account, go to
+http://github.com/abh/qpsmtpd/tree/master and click on the "fork"
+button to get your own repository.
+
+=head3 Making a working Copy
+
+ git clone git@github.com:username/qpsmtpd qpsmtpd
+
+will check out your copy into a directory called qpsmtpd
+
+=head3 Committing a change
+
+Edit the appropriate files, and be sure to run the test suite.
+
+  emacs lib/Qpsmtpd.pm # for example
+  perl Makefile.PL
+  make test
+
+When you're ready to check it in...
+
+  git add lib/Qpsmtpd.pm # to let git know you changed the file
+  git commit
+  git push origin # to send to github
+
+=head3 Merging changes back in from the master repository
+
+Tell git about the master repository.  We're going to call it 'abh'
+for now, but you could call it anything you want.  You only have to do
+this once.
+
+  git remote add abh git://github.com/abh/qpsmtpd.git
+
+Pull in data from all remote branches
+
+  git remote update
+
+Forward-port local commits to the updated upstream head
+
+  git rebase abh/master
+
+If you have a change that conflicts with an upstream change (git will
+let you know) you have two options.  You can merge it and then commit
+the merge, or you can skip it entirely:
+
+  git rebase --skip
+
+Be sure to decide whether you're going to skip before you merge, or
+you might get yourself into an odd situation.
+
+Conflicts happen because upstream committers may make minor tweaks to
+your change before applying it.
+
+=head3 Throwing away changes
+
+If you get your working copy into a state you don't like, you can
+always revert to the last commit:
+
+ git reset --hard HEAD
+
+=head3 Applying other peoples changes
+
+One easy way to apply other peoples changes is to use C<git am>.  That
+will go ahead and commit the change.  To modify it, you can use C<git
+commit --amend>.

+
+=head2 Discarding messages
+
+If you want to make the client think a message has been regularily accepted,
+but in real you delete it or send it to F</dev/null>, ..., use something
+like the following plugin and load it before your default queue plugin.
+
+  sub hook_queue {
+    my ($self, $transaction) = @_;
+    if ($transaction->notes('discard_mail')) {
+      my $msg_id = $transaction->header->get('Message-Id') || '';
+      $msg_id =~ s/[\r\n].*//s;
+      return(OK, "Queued! $msg_id");
+    }
+    return(DECLINED);
+  }
+
+
+=head2 Changing return values
+
+This is an example how to use the C<isa_plugin> method.
+
+The B<rcpt_ok_maxrelay> plugin wraps the B<rcpt_ok> plugin. The B<rcpt_ok>
+plugin checks the F<rcpthosts> and F<morercpthosts> config files for
+domains, which we accept mail for. If not found it tells the
+client that relaying is not allowed. Clients which are marked as
+C<relay clients> are excluded from this rule. This plugin counts the
+number of unsuccessfull relaying attempts and drops the connection if
+too many were made.
+
+The optional parameter I<MAX_RELAY_ATTEMPTS> configures this plugin to drop
+the connection after I<MAX_RELAY_ATTEMPTS> unsuccessful relaying attempts.
+Set to C<0> to disable, default is C<5>.
+
+Note: Do not load both (B<rcpt_ok> and B<rcpt_ok_maxrelay>). This plugin
+should be configured to run I<last>, like B<rcpt_ok>.
+
+ use Qpsmtpd::DSN;
+ 
+ sub init {
+   my ($self, $qp, @args) = @_;
+   die "too many arguments"
+     if @args > 1;
+   $self->{_count_relay_max} = defined $args[0] ? $args[0] : 5;
+   $self->isa_plugin("rcpt_ok");
+ }
+
+ sub hook_rcpt {
+   my ($self, $transaction, $recipient) = @_;
+   my ($rc, @msg) = $self->SUPER::hook_rcpt($transaction, $recipient);
+ 
+   return ($rc, @msg)
+      unless (($rc == DENY) and $self->{_count_relay_max});
+
+   my $count = 
+     ($self->qp->connection->notes('count_relay_attempts') || 0) + 1;
+   $self->qp->connection->notes('count_relay_attempts', $count);
+
+   return ($rc, @msg) unless ($count > $self->{_count_relay_max});
+   return Qpsmtpd::DSN->relaying_denied(DENY_DISCONNECT, 
+           "Too many relaying attempts"); 
+ }
+
+=head2 Results of other hooks
+
+B<NOTE:> just copied from README.plugins
+
+If we're in a transaction, the results of a callback are stored in
+
+    $self->transaction->notes( $code->{name})->{"hook_$hook"}->{return}
+
+If we're in a connection, store things in the connection notes instead.
+B<FIXME>: does the above (regarding connection notes) work?

+=head1 SMTP hooks
+
+This section covers the hooks, which are run in a normal SMTP connection. 
+The order of these hooks is like you will (probably) see them, while a mail
+is received. 
+
+Every hook receives a C<Qpsmtpd::Plugin> object of the currently 
+running plugin as the first argument. A C<Qpsmtpd::Transaction> object is 
+the second argument of the current transaction in the most hooks, exceptions 
+are noted in the description of the hook. If you need examples how the 
+hook can be used, see the source of the plugins, which are given as 
+example plugins.
+
+B<NOTE>: for some hooks (post-fork, post-connection, disconnect, deny, ok) the
+return values are ignored. This does B<not> mean you can return anything you
+want. It just means the return value is discarded and you can not disconnect
+a client with I<DENY_DISCONNECT>. The rule to return I<DECLINED> to run the
+next plugin for this hook (or return I<OK> / I<DONE> to stop processing) 
+still applies.
+
+=head2 hook_pre_connection
+
+Called by a controlling process (e.g. forkserver or prefork) after accepting 
+the remote server, but before beginning a new instance (or handing the 
+connection to the worker process).
+
+Useful for load-management and rereading large config files at some
+frequency less than once per session.
+
+This hook is available in the F<qpsmtpd-forkserver>, F<qpsmtpd-prefork> and
+F<qpsmtpd-async> flavours. 
+
+=cut 
+
+NOT FOR: apache, -server and inetd/pperl
+
+=pod
+
+B<NOTE:> You should not use this hook to do major work and / or use lookup 
+methods which (I<may>) take some time, like DNS lookups. This will slow down
+B<all> incoming connections, no other connection will be accepted while this
+hook is running!
+
+Arguments this hook receives are (B<NOTE>: currently no C<%args> for 
+F<qpsmtpd-async>):
+
+  my ($self,$transaction,%args) = @_;
+  # %args is:
+  # %args = ( remote_ip    => inet_ntoa($iaddr),
+  #           remote_port  => $port,
+  #           local_ip     => inet_ntoa($laddr),
+  #           local_port   => $lport,
+  #           max_conn_ip  => $MAXCONNIP,
+  #           child_addrs  => [values %childstatus],
+  #         );
+
+B<NOTE:> the C<$transaction> is of course C<undef> at this time.
+
+Allowed return codes are
+
+=over 4
+
+=item DENY / DENY_DISCONNECT
+
+returns a B<550> to the client and ends the connection
+
+=item DENYSOFT / DENYSOFT_DISCONNECT
+
+returns a B<451> to the client and ends the connection
+
+=back
+
+Anything else is ignored.
+
+Example plugins are F<hosts_allow> and F<connection_time>. 
+
+=head2 hook_connect
+
+It is called at the start of a connection before the greeting is sent to 
+the connecting client.
+
+Arguments for this hook are
+
+  my $self = shift;
+
+B<NOTE:> in fact you get passed two more arguments, which are C<undef> at this
+early stage of the connection, so ignore them.
+
+Allowed return codes are
+
+=over 4
+
+=item OK
+
+Stop processing plugins, give the default response
+
+=item DECLINED
+
+Process the next plugin
+
+=item DONE
+
+Stop processing plugins and dont give the default response, i.e. the plugin 
+gave the response
+
+=item DENY
+
+Return hard failure code and disconnect
+
+=item DENYSOFT
+
+Return soft failure code and disconnect
+
+=back
+
+Example plugin for this hook is the F<check_relay> plugin. 
+
+=head2 hook_helo / hook_ehlo
+
+It is called after the client sent B<EHLO> (hook_ehlo) or B<HELO> (hook_helo)
+Allowed return codes are
+
+=over 4
+
+=item DENY
+
+Return a 550 code
+
+=item DENYSOFT
+
+Return a B<450> code
+
+=item DENY_DISCONNECT / DENYSOFT_DISCONNECT
+
+as above but with disconnect
+
+=item DONE
+
+Qpsmtpd wont do anything, the plugin sent the message
+
+=item DECLINED 
+
+Qpsmtpd will send the standard B<EHLO>/B<HELO> answer, of course only 
+if all plugins hooking I<helo/ehlo> return I<DECLINED>.
+
+=back
+
+Arguments of this hook are
+
+  my ($self, $transaction, $host) = @_;
+  # $host: the name the client sent in the 
+  # (EH|HE)LO line
+
+B<NOTE:> C<$transaction> is C<undef> at this point.
+
+=head2 hook_mail_pre
+
+After the B<MAIL FROM: > line sent by the client is broken into 
+pieces by the C<hook_mail_parse()>, this hook recieves the results.
+This hook may be used to pre-accept adresses without the surrounding 
+I<E<lt>E<gt>> (by adding them) or addresses like 
+I<E<lt>user@example.com.E<gt>> or I<E<lt>user@example.com E<gt>> by 
+removing the trailing I<"."> / C<" ">.
+
+Expected return values are I<OK> and an address which must be parseable
+by C<Qpsmtpd::Address-E<gt>parse()> on success or any other constant to
+indicate failure.
+
+Arguments are 
+
+  my ($self, $transaction, $addr) = @_;
+
+=head2 hook_mail
+
+Called right after the envelope sender line is parsed (the B<MAIL FROM: >
+command). The plugin gets passed a C<Qpsmtpd::Address> object, which means 
+the parsing and verifying the syntax of the address (and just the syntax, 
+no other checks) is already done. Default is to allow the sender address. 
+The remaining arguments are the extensions defined in RFC 1869 (if sent by 
+the client).
+
+B<NOTE:> According to the SMTP protocol, you can not reject an invalid
+sender until after the B<RCPT> stage (except for protocol errors, i.e.
+syntax errors in address). So store it in an C<$transaction-E<gt>note()> and 
+process it later in an rcpt hook.
+
+Allowed return codes are
+
+=over 4
+
+=item OK
+
+sender allowed
+
+=item DENY
+
+Return a hard failure code
+
+=item DENYSOFT
+
+Return a soft failure code
+
+=item DENY_DISCONNECT / DENYSOFT_DISCONNECT
+
+as above but with disconnect
+
+=item DECLINED
+
+next plugin (if any)
+
+=item DONE
+
+skip further processing, plugin sent response
+
+=back
+
+Arguments for this hook are 
+
+  my ($self,$transaction, $sender, %args) = @_;
+  # $sender: an Qpsmtpd::Address object for 
+  # sender of the message
+
+Example plugins for the C<hook_mail> are F<require_resolvable_fromhost>
+and F<check_badmailfrom>.
+
+=head2 hook_rcpt_pre
+
+See C<hook_mail_pre>, s/MAIL FROM:/RCPT TO:/.
+
+=head2 hook_rcpt
+
+This hook is called after the client sent an I<RCPT TO: > command (after 
+parsing the line). The given argument is parsed by C<Qpsmtpd::Address>, 
+then this hook is called. Default is to deny the mail with a soft error 
+code. The remaining arguments are the extensions defined in RFC 1869
+(if sent by the client).
+
+Allowed return codes
+
+=over 4
+
+=item OK
+
+recipient allowed
+
+=item DENY
+
+Return a hard failure code, for example for an I<User does not exist here> 
+message.
+
+=item DENYSOFT
+
+Return a soft failure code, for example if the connect to a user lookup 
+database failed
+
+=item DENY_DISCONNECT / DENYSOFT_DISCONNECT
+
+as above but with disconnect
+
+=item DONE
+
+skip further processing, plugin sent response
+
+=back
+
+Arguments are
+
+  my ($self, $transaction, $recipient, %args) = @_;
+  # $rcpt = Qpsmtpd::Address object with 
+  # the given recipient address
+
+Example plugin is F<rcpt_ok>.
+
+=head2 hook_data
+
+After the client sent the B<DATA> command, before any data of the message
+was sent, this hook is called. 
+
+B<NOTE:> This hook, like B<EHLO>, B<VRFY>, B<QUIT>, B<NOOP>, is an 
+endpoint of a pipelined command group (see RFC 1854) and may be used to 
+detect ``early talkers''. Since svn revision 758 the F<check_earlytalker>
+plugin may be configured to check at this hook for ``early talkers''.
+
+Allowed return codes are
+
+=over 4
+
+=item DENY
+
+Return a hard failure code
+
+=item DENYSOFT
+
+Return a soft failure code
+
+=item DENY_DISCONNECT / DENYSOFT_DISCONNECT
+
+as above but with disconnect
+
+=item DONE
+
+Plugin took care of receiving data and calling the queue (not recommended)
+
+B<NOTE:> The only real use for I<DONE> is implementing other ways of
+receiving the message, than the default... for example the CHUNKING SMTP
+extension (RFC 1869, 1830/3030) ... a plugin for this exists at 
+http://svn.perl.org/qpsmtpd/contrib/vetinari/experimental/chunking, but it
+was never tested ``in the wild''.
+
+=back
+
+Arguments:
+
+  my ($self, $transaction) = @_;
+
+Example plugin is F<greylisting>.
+
+=head2 hook_received_line
+
+If you wish to provide your own Received header line, do it here. You can use
+or discard any of the given arguments (see below).
+
+Allowed return codes:
+
+=over 4
+
+=item OK, $string
+
+use this string for the Received header.
+
+=item anything else
+
+use the default Received header
+
+=back
+
+Arguments are
+
+ my ($self, $transaction, $smtp, $auth, $sslinfo) = @_;
+ # $smtp - the SMTP type used (e.g. "SMTP" or "ESMTP").
+ # $auth - the Auth header additionals.
+ # $sslinfo - information about SSL for the header.
+
+=head2 data_headers_end
+
+This hook fires after all header lines of the message data has been received.
+Defaults to doing nothing, just continue processing. At this step,
+the sender is not waiting for a reply, but we can try and prevent him from
+sending the entire message by disconnecting immediately. (Although it is
+likely the packets are already in flight due to buffering and pipelining).
+
+B<NOTE:> BE CAREFUL! If you drop the connection legal MTAs will retry again 
+and again, spammers will probably not. This is not RFC compliant and can lead
+to an unpredictable mess. Use with caution.
+
+Why this hook may be useful for you, see 
+L<http://www.nntp.perl.org/group/perl.qpsmtpd/2009/02/msg8502.html>, ff.
+
+Allowed return codes:
+
+=over 4
+
+=item DENY_DISCONNECT
+
+Return B<554 Message denied> and disconnect
+
+=item DENYSOFT_DISCONNECT
+
+Return B<421 Message denied temporarily> and disconnect
+
+=item DECLINED
+
+Do nothing
+
+=back
+
+Arguments:
+
+  my ($self, $transaction) = @_; 
+
+B<FIXME:> check arguments
+
+=head2 hook_data_post
+
+The C<data_post> hook is called after the client sent the final C<.\r\n> 
+of a message, before the mail is sent to the queue.
+
+Allowed return codes are
+
+=over 4
+
+=item DENY
+
+Return a hard failure code
+
+=item DENYSOFT
+
+Return a soft failure code
+
+=item DENY_DISCONNECT / DENYSOFT_DISCONNECT
+
+as above but with disconnect
+
+=item DONE
+
+skip further processing (message will not be queued), plugin gave the response.
+
+B<NOTE:> just returning I<OK> from a special queue plugin does (nearly) 
+the same (i.e. dropping the mail to F</dev/null>) and you don't have to 
+send the response on your own.
+
+If you want the mail to be queued, you have to queue it manually!
+
+=back
+
+Arguments:
+
+  my ($self, $transaction) = @_;
+
+Example plugins: F<spamassassin>, F<virus/clamdscan>
+
+=head2 hook_queue_pre
+
+This hook is run, just before the mail is queued to the ``backend''. You 
+may modify the in-process transaction object (e.g. adding headers) or add 
+something like a footer to the mail (the latter is not recommended).
+
+Allowed return codes are 
+
+=over 4
+
+=item DONE
+
+no queuing is done
+
+=item OK / DECLINED
+
+queue the mail
+
+=back
+
+=head2 hook_queue
+
+When all C<data_post> hooks accepted the message, this hook is called. It 
+is used to queue the message to the ``backend''.
+
+Allowed return codes:
+
+=over 4
+
+=item DONE
+
+skip further processing (plugin gave response code)
+
+=item OK
+
+Return success message, i.e. tell the client the message was queued (this
+may be used to drop the message silently).
+
+=item DENY
+
+Return hard failure code
+
+=item DENYSOFT
+
+Return soft failure code, i.e. if disk full or other temporary queuing 
+problems
+
+=back
+
+Arguments:
+
+  my ($self, $transaction) = @_;
+
+Example plugins: all F<queue/*> plugins
+
+=head2 hook_queue_post
+
+This hook is called always after C<hook_queue>. If the return code is 
+B<not> I<OK>, a message (all remaining return values) with level I<LOGERROR> 
+is written to the log.
+Arguments are
+
+ my $self = shift;
+ 
+B<NOTE:> C<$transaction> is not valid at this point, therefore not mentioned.
+
+
+=head2 hook_reset_transaction
+
+This hook will be called several times. At the beginning of a transaction 
+(i.e. when the client sends a B<MAIL FROM:> command the first time), 
+after queueing the mail and every time a client sends a B<RSET> command.
+Arguments are 
+
+ my ($self, $transaction) = @_;
+
+B<NOTE:> don't rely on C<$transaction> being valid at this point.
+
+=head2 hook_quit
+
+After the client sent a B<QUIT> command, this hook is called (before the
+C<hook_disconnect>).
+
+Allowed return codes
+
+=over 4
+
+=item DONE
+
+plugin sent response
+
+=item DECLINED
+
+next plugin and / or qpsmtpd sends response
+
+=back
+
+Arguments: the only argument is C<$self>
+
+=cut 
+
+### XXX: FIXME pass the rest of the line to this hook?
+
+=pod
+
+Expample plugin is the F<quit_fortune> plugin.
+
+=head2 hook_disconnect
+
+This hook will be called from several places: After a plugin returned 
+I<DENY(|SOFT)_DISCONNECT>, before connection is disconnected or after the 
+client sent the B<QUIT> command, AFTER the quit hook and ONLY if no plugin 
+hooking C<hook_quit> returned I<DONE>.
+
+All return values are ignored, arguments are just C<$self>
+
+Example plugin is F<logging/file>
+
+=head2 hook_post_connection
+
+This is the counter part of the C<pre-connection> hook, it is called 
+directly before the connection is finished, for example, just before the 
+qpsmtpd-forkserver instance exits or if the client drops the connection 
+without notice (without a B<QUIT>). This hook is not called if the qpsmtpd
+instance is killed.
+
+=cut 
+
+FIXME: we should run this hook on a ``SIGHUP'' or some other signal?
+
+=pod 
+
+The only argument is C<$self> and all return codes are ignored, it would 
+be too late anyway :-).
+
+Example: F<connection_time>
+
+=head1 Parsing Hooks
+
+Before the line from the client is parsed by 
+C<Qpsmtpd::Command-E<gt>parse()> with the built in parser, these hooks 
+are called. They can be used to supply a parsing function for the line,
+which will be used instead of the built in parser.
+
+The hook must return two arguments, the first is (currently) ignored,
+the second argument must be a (CODE) reference to a sub routine. This sub 
+routine receives three arguments:
+
+=over 4
+
+=item $self
+
+the plugin object
+
+=item $cmd
+
+the command (i.e. the first word of the line) sent by the client
+
+=item $line
+
+the line sent by the client without the first word
+
+=back
+
+Expected return values from this sub are I<DENY> and a reason which is 
+sent to the client or I<OK> and the C<$line> broken into pieces according
+to the syntax rules for the command.
+
+B<NOTE: ignore the example from C<Qpsmtpd::Command>, the C<unrecognized_command_parse> hook was never implemented,...>
+
+=head2 hook_helo_parse / hook_ehlo_parse
+
+The provided sub routine must return two or more values. The first is 
+discarded, the second is the hostname (sent by the client as argument 
+to the B<HELO> / B<EHLO> command). All other values are passed to the 
+helo / ehlo hook. This hook may be used to change the hostname the client
+sent... not recommended, but if your local policy says only to accept
+I<HELO> hosts with FQDNs and you have a legal client which can not be 
+changed to send his FQDN, this is the right place.
+
+=head2 hook_mail_parse / hook_rcpt_parse
+
+The provided sub routine must return two or more values. The first is 
+either I<OK> to indicate that parsing of the line was successfull
+or anything else to bail out with I<501 Syntax error in command>. In
+case of failure the second argument is used as the error message for the 
+client.
+
+If parsing was successfull, the second argument is the sender's / 
+recipient's address (this may be without the surrounding I<E<lt>> and 
+I<E<gt>>, don't add them here, use the C<hook_mail_pre()> / 
+C<hook_rcpt_pre()> methods for this). All other arguments are 
+sent to the C<mail / rcpt> hook as B<MAIL> / B<RCPT> parameters (see 
+RFC 1869 I<SMTP Service Extensions> for more info). Note that 
+the mail and rcpt hooks expect a list of key/value pairs as the 
+last arguments.
+
+=head2 hook_auth_parse
+
+B<FIXME...>
+
+=head1 Special hooks
+
+Now some special hooks follow. Some of these hooks are some internal hooks, 
+which may be used to alter the logging or retrieving config values from 
+other sources (other than flat files) like SQL databases.
+
+=head2 hook_logging

-=head1 SMTP hooks
-
-This section covers the hooks, which are run in a normal SMTP connection. 
-The order of these hooks is like you will (probably) see them, while a mail
-is received. 
-
-Every hook receives a C<Qpsmtpd::Plugin> object of the currently 
-running plugin as the first argument. A C<Qpsmtpd::Transaction> object is 
-the second argument of the current transaction in the most hooks, exceptions 
-are noted in the description of the hook. If you need examples how the 
-hook can be used, see the source of the plugins, which are given as 
-example plugins.
-
-B<NOTE>: for some hooks (post-fork, post-connection, disconnect, deny, ok) the
-return values are ignored. This does B<not> mean you can return anything you
-want. It just means the return value is discarded and you can not disconnect
-a client with I<DENY_DISCONNECT>. The rule to return I<DECLINED> to run the
-next plugin for this hook (or return I<OK> / I<DONE> to stop processing) 
-still applies.
-
-=head2 hook_pre_connection
-
-Called by a controlling process (e.g. forkserver or prefork) after accepting 
-the remote server, but before beginning a new instance (or handing the 
-connection to the worker process).
-
-Useful for load-management and rereading large config files at some
-frequency less than once per session.

-  my ($self, $transaction, $addr) = @_;
-
-=head2 hook_mail
-
-Called right after the envelope sender line is parsed (the B<MAIL FROM: >
-command). The plugin gets passed a C<Qpsmtpd::Address> object, which means 
-the parsing and verifying the syntax of the address (and just the syntax, 
-no other checks) is already done. Default is to allow the sender address. 
-The remaining arguments are the extensions defined in RFC 1869 (if sent by 
-the client).
-
-B<NOTE:> According to the SMTP protocol, you can not reject an invalid
-sender until after the B<RCPT> stage (except for protocol errors, i.e.

-was sent, this hook is called. 
-
-B<NOTE:> This hook, like B<EHLO>, B<VRFY>, B<QUIT>, B<NOOP>, is an 
-endpoint of a pipelined command group (see RFC 1854) and may be used to

- # $auth - the Auth header additionals.
- # $sslinfo - information about SSL for the header.
-
-=head2 data_headers_end
-
-This hook fires after all header lines of the message data has been received.
-Defaults to doing nothing, just continue processing. At this step,
-the sender is not waiting for a reply, but we can try and prevent him from
-sending the entire message by disconnecting immediately. (Although it is
-likely the packets are already in flight due to buffering and pipelining).
-
-B<NOTE:> BE CAREFUL! If you drop the connection legal MTAs will retry again 
-and again, spammers will probably not. This is not RFC compliant and can lead
-to an unpredictable mess. Use with caution.

-
-=head2 hook_helo_parse / hook_ehlo_parse
-
-The provided sub routine must return two or more values. The first is 
-discarded, the second is the hostname (sent by the client as argument 
-to the B<HELO> / B<EHLO> command). All other values are passed to the 
-helo / ehlo hook. This hook may be used to change the hostname the client
-sent... not recommended, but if your local policy says only to accept
-I<HELO> hosts with FQDNs and you have a legal client which can not be 
-changed to send his FQDN, this is the right place.
-
-=head2 hook_mail_parse / hook_rcpt_parse
-
-The provided sub routine must return two or more values. The first is 
-either I<OK> to indicate that parsing of the line was successfull
-or anything else to bail out with I<501 Syntax error in command>. In
-case of failure the second argument is used as the error message for the 
-client.
-
-If parsing was successfull, the second argument is the sender's / 
-recipient's address (this may be without the surrounding I<E<lt>> and 
-I<E<gt>>, don't add them here, use the C<hook_mail_pre()> / 
-C<hook_rcpt_pre()> methods for this). All other arguments are 
-sent to the C<mail / rcpt> hook as B<MAIL> / B<RCPT> parameters (see 
-RFC 1869 I<SMTP Service Extensions> for more info). Note that 
-the mail and rcpt hooks expect a list of key/value pairs as the 
-last arguments.

-This is a walk through a new queue plugin, which queues the mail to a (remote)
-QMQP-Server.
-
-First step is to pull in the necessary modules
-
- use IO::Socket;
- use Text::Netstring qw( netstring_encode 
-                         netstring_decode 
-                         netstring_verify 
-                         netstring_read );
-
-We know, we need a server to send the mails to. This will be the same 
-for every mail, so we can use arguments to the plugin to configure this 
-server (and port).
-
-Inserting this static config is done in C<register()>:
-
-  sub register {
-    my ($self, $qp, @args) = @_;
-  
-    die "No QMQP server specified in qmqp-forward config"

-    }
-  
-    $self->log(LOGWARN, "WARNING: Ignoring additional arguments.") 
-      if (@args > 2);
-  }
-
-We're going to write a queue plugin, so we need to hook to the I<queue>
-hook.
-
-  sub hook_queue {
-    my ($self, $transaction) = @_;
-  
-    $self->log(LOGINFO, "forwarding to $self->{_qmqp_server}:"

-
-The first step is to open a connection to the remote server.
-
-   my $sock = IO::Socket::INET->new(

-The first idea is to build the package we send, in the order described
-in the paragraph above:

-  my $message = $transaction->header->as_string;
-  $transaction->body_resetpos;
-  while (my $line = $transaction->body_getline) {

-      $self->_disconnect($sock);
-      return(DECLINED, "Failed to print to socket: $err");
-    };
-
-This would mean, we have to hold the full message in memory... Not good 
-for large messages, and probably even slower (for large messages).
-
-Luckily it's easy to build a netstring without the help of the
-C<Text::Netstring> module if you know the size of the string (for more
-info about netstrings see L<http://cr.yp.to/proto/netstrings.txt>).
-
-We start with the sender and recipient addresses:

-message is.
-
-  $headers   = $transaction->header->as_string;

-
-We've got everything we need. Now build the netstrings for the full package
-and the message.
-
-First the beginning of the netstring of the full package
-
-  # (+ 2: the ":" and "," of the message's netstring)

-    };

-=head2 Changing return values
-
-This is an example how to use the C<isa_plugin> method.
-
-The B<rcpt_ok_maxrelay> plugin wraps the B<rcpt_ok> plugin. The B<rcpt_ok>
-plugin checks the F<rcpthosts> and F<morercpthosts> config files for
-domains, which we accept mail for. If not found it tells the
-client that relaying is not allowed. Clients which are marked as
-C<relay clients> are excluded from this rule. This plugin counts the
-number of unsuccessfull relaying attempts and drops the connection if
-too many were made.
-
-The optional parameter I<MAX_RELAY_ATTEMPTS> configures this plugin to drop
-the connection after I<MAX_RELAY_ATTEMPTS> unsuccessful relaying attempts.
-Set to C<0> to disable, default is C<5>.
-
-Note: Do not load both (B<rcpt_ok> and B<rcpt_ok_maxrelay>). This plugin
-should be configured to run I<last>, like B<rcpt_ok>.
-
- use Qpsmtpd::DSN;
- 
- sub init {
-   my ($self, $qp, @args) = @_;
-   die "too many arguments"
-     if @args > 1;
-   $self->{_count_relay_max} = defined $args[0] ? $args[0] : 5;
-   $self->isa_plugin("rcpt_ok");
- }
-
- sub hook_rcpt {
-   my ($self, $transaction, $recipient) = @_;
-   my ($rc, @msg) = $self->SUPER::hook_rcpt($transaction, $recipient);
- 
-   return ($rc, @msg)
-      unless (($rc == DENY) and $self->{_count_relay_max});
-
-   my $count =

-   return Qpsmtpd::DSN->relaying_denied(DENY_DISCONNECT, 
-           "Too many relaying attempts"); 
- }
-
-=head2 Results of other hooks
-
-B<NOTE:> just copied from README.plugins
-
-If we're in a transaction, the results of a callback are stored in
-
-    $self->transaction->notes( $code->{name})->{"hook_$hook"}->{return}
-
-If we're in a connection, store things in the connection notes instead.
-B<FIXME>: does the above (regarding connection notes) work?

+The client starts with a safe 8-bit text message. It encodes the message
+as the byte string C<firstline\012secondline\012 ... \012lastline>. (The
+last line is usually, but not necessarily, empty.) The client then encodes
+this byte string as a netstring. The client also encodes the envelope
+sender address as a netstring, and encodes each envelope recipient address
+as a netstring.
+
+The client concatenates all these netstrings, encodes the concatenation
+as a netstring, and sends the result.

+
+The first idea is to build the package we send, in the order described
+in the paragraph above:
+
+  my $message = $transaction->header->as_string;
+  $transaction->body_resetpos;
+  while (my $line = $transaction->body_getline) {
+    $message .= $line;
+  }
+  $message  = netstring_encode($message);
+  $message .= netstring_encode($transaction->sender->address);
+  for ($transaction->recipients) {
+    push @rcpt, $_->address;
+  }
+  $message .= join "", netstring_encode(@rcpt);
+  print $sock netstring_encode($message)
+    or do {
+      my $err = $!;
+      $self->_disconnect($sock);
+      return(DECLINED, "Failed to print to socket: $err");
+    };
+
+This would mean, we have to hold the full message in memory... Not good 
+for large messages, and probably even slower (for large messages).
+
+Luckily it's easy to build a netstring without the help of the
+C<Text::Netstring> module if you know the size of the string (for more
+info about netstrings see L<http://cr.yp.to/proto/netstrings.txt>).
+
+We start with the sender and recipient addresses:
+
+  my ($addrs, $headers, @rcpt);
+  $addrs = netstring_encode($transaction->sender->address);
+  for ($transaction->recipients) {
+    push @rcpt, $_->address;
+  }
+  $addrs .= join "", netstring_encode(@rcpt);
+
+Ok, we got the sender and the recipients, now let's see what size the
+message is.
+
+  $headers   = $transaction->header->as_string;
+  my $msglen = length($headers) + $transaction->body_length;
+
+We've got everything we need. Now build the netstrings for the full package
+and the message.
+
+First the beginning of the netstring of the full package
+
+  # (+ 2: the ":" and "," of the message's netstring)
+  print $sock ($msglen + length($msglen) + 2 + length($addrs))
+               .":"
+               ."$msglen:$headers" ### beginning of messages netstring

+      return(DECLINED, 
+             "Failed to print to socket: $err");
+    };
+
+Go to beginning of the body
+
+  $transaction->body_resetpos;
+
+If the message is spooled to disk, read the message in
+blocks and write them to the server
+
+  if ($transaction->body_fh) {
+    my $buff;
+    my $size = read $transaction->body_fh, $buff, 4096;

+is morally equivalent to the 250 response to DATA in SMTP; it is subject
+to the reliability requirements of RFC 1123, section 5.3.3. Z means

This reverts commit ea86b9fdb242be7b4aca8a5acfec6ad30360fc9f.

Jared said...
I originally considered these functionally identical, but they are
not. The new code, called with, say, $txn->notes('discard',undef),
would result in evaluation as if it were a 'get' method rather than
setting the 'discard' note to undef.  That seems quite dangerous.  I
suggest either reverting the language back to the '@_ and' model, or
else doing something like:

Subject: [PATCH 0893/1467] Call add_recipient correctly in kavscanner plugin

plugins/virus/kavscanner calls $transaction->add_recipient($_->address)
on a list of Mail::Address objects, but add_recipient() clearly
documents that it takes Qpsmtpd::Address (or compatible) objects, not
strings.  This is a bit of a drive-by fix inspired by a grep through the
codebase for calls to add_recipient().

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Qpsmtpd Connection and Transaction objects support notes() methods which
are conventionally used to pass data between plugins.  This adds the
same functionality to Address objects.  This should make it easier for
plugins to begin supporting message handling based on per-user
configuration directives.

Qpsmtpd::Connection::notes() and Qpsmtpd::Transaction::notes() have
identicaly functionality; however, the POD documentation for Connection
notes is fairly brief while the documentation for Transaction notes is
longer and more helpful.  This updates the Connection notes documention
to be consistent with its Transaction counterpart.

+=head1 NAME
+
+rcpt_regexp - check recipients against a list of regular expressions
+
+=head1 DESCRIPTION
+
+B<rcpt_regexp> reads a list of regular expressions, return codes and comments
+from the I<rcpt_regexp> config file. If the regular expression does NOT match
+I<m#^(/.*/)$#>, it is used as a string which is compared with I<eq lc($rcpt)>.
+The recipient addresses are checked against this list, and if the first 
+matches, the return code from that line and the comment are returned to
+qpsmtpd. Return code can be any valid plugin return code from 
+L<Qpsmtpd::Constants>. Matching is always done case insenstive. 
+
+=head1 CONFIG FILE
+
+The config file I<rcpt_regexp> contains lines with a perl RE, including the 
+"/"s, a return code and a comment, which will be returned to the sender, if 
+the code is not OK or DECLINED. Example:
+
+  # rcpt_regexp - config for rcpt_regexp plugin
+  me@myhost.org           OK       Accepting mail
+  /^user\d+\@doma\.in$/   OK       Accepting mail
+  info@myhost.com         DENY     User not found.
+  /^unused\@.*/           DENY     User not found.
+  /^.*$/                  DECLINED Fall through to next rcpt plugin
+
+=head1 NOTE
+
+The C<rcpt_regexp> config file should be writeable by trusted users only: the
+regexes are compiled with I<eval()>.
+
+=head1 COPYRIGHT AND LICENSE
+
+Copyright (c) 2005 Hanno Hecker

+=head1 DESCRIPTION
+
+The logging/apache plugin uses the apache logging mechanism to write its
+messages to the apache error log.
+
+=head1 INSTALL AND CONFIG
+
+Place this plugin in the plugin/logging directory beneath the standard
+qpsmtpd installation. Edit the config/logging file and add a line like
+this:
+
+  logging/apache
+
+To change what is shown in the logs, change the I<LogLevel> directive in
+the virtual host config for Qpsmtpd and maybe change the I<ErrorLog> log
+file:
+
+         <VirtualHost _default_:25>
+          PerlSetVar QpsmtpdDir /path/to/qpsmtpd
+          PerlModule Apache::Qpsmtpd
+          PerlProcessConnectionHandler Apache::Qpsmtpd
+          LogLevel debug
+          ErrorLog /var/log/apache2/qpsmtpd.log
+         </VirtualHost>

Subject: [PATCH 0904/1467] Change transaction->add_recipient to prevent adding
 undef/empty recipients
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Improve Qpsmtpd::Transaction::add_recipient syntax

Update Qpsmtpd::Transaction::add_recipient to use slightly clearer
language, and add 'if $rcpt' to prevent undef recipients from
being added -- in this case, the '@_ and' syntax allowing this set
method to set undef is undesirable, since you shouldn't be adding undef as
a recipient.

+=head1 Qpsmtpd configuration
+
+The default way of setting config values is placing files with the
+name of the config variable in the config directory F<config/>, like
+qmail's F</var/qmail/control/> directory. NB: F</var/qmail/control> (or 
+F<$ENV{QMAIL}/control>) is used if a file does not exist in C<config/>. 
+The location of the C<config/> directory can be set via the 
+I<QPSMTPD_CONFIG> environment variable and defaults to the current 
+working directory.
+
+Any empty line or lines starting with C<#> are ignored. You may use a
+plugin which hooks the C<config> hook to store the settings in some other
+way. See L<docs/plugins.pod> and L<docs/hooks.pod> for more info on this.
+Some settings still have to go in files, because they are loaded before
+any plugin can return something via the C<config> hook: C<me>, C<logging>,
+C<plugin_dirs> and of course C<plugins>. B<FIXME: more?>
+
+=head2 Core settings
+
+These settings are used by the qpsmtpd core. Any other setting is (hopefully)
+documented by the corresponding plugin. Some settings of important plugins
+are shown below in L</Plugin settings>.
+
+=over 4
+
+=item plugins
+
+The main config file, where all used plugins and their arguments are listed.
+
+=item me
+
+Sets the hostname which is used all over the place: in the greeting message,
+the I<Received: >header, ...
+Default is whatever Sys::Hostname's hostname() returns.
+
+=item plugin_dirs
+
+Where to search for plugins (one directory per line), defaults to F<./plugins>.
+
+=item logging
+
+Sets the primary logging destination, see F<plugins/logging/*>. Format
+is the same as it's used for the F<plugins> config file. B<NOTE:> only
+the first non empty line is used (lines starting with C<#> are counted
+as empty).
+
+=item loglevel
+
+This is not used anymore, I<only> if no F<logging/> plugin is in use. Use a
+logging plugin.
+
+=item databytes
+
+Maximum size a message may be. Without this setting, there is no limit on the 
+size. Should be something less than the backend MTA has set as it's maximum
+message size (if there is one).
+
+=item size_threshold
+
+When a message is greater than the size given in this config file, it will be
+spooled to disk. You probably want to enable spooling to disk for most virus
+scanner plugins and F<spamassassin>.
+
+=item smtpgreeting
+
+Override the default SMTP greeting with this string.
+
+=item spool_dir
+
+Where temporary files are stored, defaults to F<tmp/>. 
+B<FIXME: is this correct?>
+
+=item spool_perms
+
+Permissions of the I<spool_dir>, default is C<0700>. You probably have to
+change the defaults for some scanners (e.g. the F<clamdscan> plugin).
+
+=item timeout
+
+=item timeoutsmtpd
+
+Set the timeout for the clients, C<timeoutsmtpd> is the qmail smtpd control
+file, C<timeout> the qpsmtpd file. Default is 1200 seconds.
+
+=item tls_before_auth
+
+If set to a true value, clients will have to initiate an SSL secured 
+connection before any auth succeeds, defaults to C<0>.
+
+=back
+
+=head2 Plugin settings
+
+=over 4
+
+=item rcpthosts, morercpthosts
+
+Plugin: I<rcpt_ok>
+
+Domains listed in these files will be accepted as valid local domains,
+anything else is rejected with a C<Relaying denied> message. If an entry
+in the C<rcpthosts> file starts with a C<.>, mails to anything ending with
+this string will be accepted, e.g.:
+ 
+ example.com
+ .example.com
+
+will accept mails for C<user@example.com> and C<user@something.example.com>.
+The C<morercpthosts> file ist just checked for exact (case insensitive) 
+matches.
+
+=item hosts_allow
+
+Plugin: F<hosts_allow>.
+
+Don't use this config file. The plugin itself is required to set the
+maximum number of concurrent connections. This config setting should 
+only be used for some extremly rude clients: if list is too big it will
+slow down accepting new connections.
+
+=item relayclients
+=item morerelayclients
+
+Plugin: F<check_relay>
+
+Allow relaying for hosts listed in this file. The C<relayclients> file accepts
+IPs and CIDR entries. The C<morercpthosts> file accepts IPs and C<prefixes> 
+like C<192.168.2.> (note the trailing dot!). With the given example any host
+which IP starts with C<192.168.2.> may relay via us. 
+
+=item dnsbl_zones
+
+Plugin: F<dnsbl>
+
+This file specifies the RBL zones list, used by the dnsbl plugin. Ihe IP 
+address of each connecting host will be checked against each zone given.
+A few sample DNSBLs are listed in the sample config file, but you should
+evaluate the efficacy and listing policies of a DNSBL before using it.
+
+See also C<dnsbl_allow> and C<dnsbl_rejectmsg> in the documentation of the
+C<dnsbl> plugin
+
+=item require_resolvable_fromhost
+
+Plugin: F<require_resolvable_fromhost>
+
+Reject sender addresses where the MX is unresolvable, i.e. a boolean value
+is the only value in this file. If the MX resolves to something, reject the
+sender address if it resolves to something listed in the 
+F<invalid_resolvable_fromhost> config file. The I<invalid_resolvable_fromhost>
+expects IP addresses or CIDR (i.e. C<network/mask> values) one per line, IPv4
+only currenlty.

Subject: [PATCH 0911/1467] Close spamd socket when we're finished with it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

QP's connection to spamd unnecessarily persists beyond the run of the
spamassassin plugin itself.  This closes the socket as soon as we're
finished using it.

Subject: [PATCH 0915/1467] prefork: support --listen-address for consistency
 with forkserver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

forkserver uses --listen-address to specify the listening socket address, while
prefork uses --interface.  Add the former as an alias for the latter, for
consistency & ease of integration.  The two still aren't commandline-compatible,
but they're fairly close.

While writing a plugin for our new spamfilter implementation I noticed
some minor error in the documentation. From the documentation it
sounds like the hook_ok and hook_deny hooks get the previous hook as
parameter.. The truth is: it is the previous plugin.

Subject: [PATCH 0930/1467] fix default reason handling

Tomas Lee <j533xdbjwfgdbsv@jetable.net> pointed out that
cab7466c08fec71c48cba5a77beee08ec3b190a4 broke the default badmailfrom
reason.

This fixes that functionality and simplifies the code a little.

+=head1 NAME
+
+file_connection - Simple per session log-to-file logging for qpsmtpd
+
+=head1 DESCRIPTION
+
+The 'file_connection' logging plugin for qpsmtpd records qpsmtpd log messages into a
+file (or a named pipe, if you prefer.)
+
+The file is reopened for each connection. To facilitate automatic
+logfile switching the filename can contain strftime conversion
+specifiers, which are expanded immediately before opening the file. This
+ensures that a single connection is never split across logfiles.
+
+The list of supported conversion specifiers depends on the strftime
+implementation of your C library. See strftime(3) for details.
+Additionally, %i exands to a (hopefully) unique session-id.
+
+
+=head1 CONFIGURATION
+
+To enable the logging plugin, add a line of this form to the qpsmtpd plugins
+configuration file:
+
+=over
+
+logging/file_connection [loglevel I<level>] I<path>
+
+For example:
+
+logging/file_connection loglevel LOGINFO /var/log/qpsmtpd/%Y-%m-%d
+
+=back
+
+Multiple instances of the plugin can be configured by appending :I<N> for any
+integer(s) I<N>, to log to multiple files simultaneously, e.g. to log critical
+errors and normally verbose logs elsewhere.
+
+The following optional configuration setting can be supplied:
+
+=over
+
+=item loglevel I<loglevel>
+
+The internal log level below which messages will be logged.  The I<loglevel>
+given should be chosen from this list.  Priorities count downward (for example,
+if LOGWARN were selected, LOGERROR, LOGCRIT and LOGEMERG messages would be
+logged as well):
+
+=over
+
+=item B<LOGDEBUG>
+
+=item B<LOGINFO>
+
+=item B<LOGNOTICE>
+
+=item B<LOGWARN>
+
+=item B<LOGERROR>
+
+=item B<LOGCRIT>
+
+=item B<LOGALERT>
+
+=item B<LOGEMERG>
+
+=back
+
+=back
+
+
+The chosen I<path> should be writable by the user running qpsmtpd; it will be
+created it did not already exist, and appended to otherwise.

+qpsmtpd is a flexible smtpd daemon written in Perl. Apart from the core
+SMTP features, all functionality is implemented in small "extension
+plugins" using the easy to use object oriented plugin API.
+
+qpsmtpd was originally written as a drop-in qmail-smtpd replacement, but
+now it also includes a smtp forward and a postfix "backend".

Only ignore config, blib, pm_to_blib, cover_db at the top level.

Ignore any file (or more likely symlink) at the top level named
config. (This is so you can symlink config -> config.sample/)

Subject: [PATCH 0950/1467] Custom spam tag subject munging in spamassasin
 plugin

Hi all!

I have written a patch to allow the spamassasin plugin to have a custom
spam tag read in from a configuration file as opposed to the default ***
SPAM *** that is hard coded.

When the configuration file (spamsubjectprefix) is not defined or empty
the default value still applies, if it is provided the value from the
configuration file is used.

Any change this can be considered for implementation as we would really
like to have it for SME Server.

Kind regards,

Jonathan

Subject: [PATCH 0955/1467] Use BSMTP response code; misc cleanups

Exim's BSMTP interface will indicate the SMTP response to the exchange;
actually use it rather than assuming all errors are 400-class soft ones.

Tolerate $transaction->header returning undef (since it evidently can under
some conditions).

Convert a few errant tabs to spaces.

Fix vi modeline.

Subject: [PATCH 0956/1467] AUTH PLAIN bug with qpsmtpd and alpine

Trying to get SMTP auth working with alpine, I came across a bug.
Alpine sends AUTH PLAIN and waits for a 334 response, then sends the
auth string. According to the RFC, the server should reply with 334
and a nothing else, but in Auth.pm qpsmtpd responds with "334 Please
continue."   the "Please continue" is interpreted as a non-zero
length initial challenge which causes alpine (and maybe other
clients?) to abort the session.

Subject: [PATCH 0958/1467] fixed issue #29: config now caches returned value

Qpsmtpd::config now checks cache, hooks, qmail_config, default in this
order and returns the first match. In any case the returned value is
stored in the cache, so subsequent calls to Qpsmtpd::config return the
same value (unless the cache is cleared).

Subject: [PATCH 0965/1467] Header check config/logical-inversion fix

Jost Krieger pointed out that the documentation for the header check called
for a config_headers, but the code actually implemented scan_headers.  Updated
to accept either.  Also the condition for actually checking/skipping the
headers was inverted.

Also whitespace fixes.

+
+check_bogus_bounce - Check that a bounce message isn't bogus
+
+=head1 DESCRIPTION
+
+This plugin is designed to reject bogus bounce messages.
+
+In our case a bogus bounce message is defined as a bounce message
+which has more than a single recipient.
+
+=head1 CONFIGURATION
+
+Only a single argument is recognized and is assumed to be the default
+action.  Valid settings are:
+
+=over 8
+
+=item log
+
+Merely log the receipt of the bogus bounce (the default behaviour).
+
+=item deny
+
+Deny with a hard error code.
+
+=item denysoft
+
+Deny with a soft error code.

+=head1 NAME
+
+auth_checkpassword - Authenticate against a DJB style checkpassword program
+
+=head1 DESCRIPTION
+
+This plugin authenticates users against a DJB style checkpassword
+program. Unlike previous checkpassword implementations, this plugin
+expects qpsmtpd to be running as the qpsmtpd user. Privilege
+escalation can be attained by running the checkpassword binary setuid
+or with sudo.
+
+=head1 CONFIGURATION
+
+Configure the path to your checkpassword binary:
+
+ echo "/usr/local/vpopmail/bin/vchkpw /usr/bin/true" > ~qpsmtpd/config/smtpauth-checkpassword
+
+vchkpw is the checkpassword program provided by vpopmail. Substitute
+your own checkpassword app as appropriate.
+
+If you are using vchkpw and this plugin is being executed by a user ID
+other than 89 or 0 (as is the default), and the vchkpw binary is not
+setuid (as is the default), this plugin will automatically prepend the
+vchkpw command with sudo. If that is the case, you must configure sudo
+by adding these two lines to your sudoers file:
+
+  Defaults:qpsmtpd	closefrom_override
+  qpsmtpd  ALL = (ALL) NOPASSWD: /usr/local/vpopmail/bin/vchkpw
+
+The closefrom_override option is necessary because, by default, sudo
+appropriates the first 3 file descriptors. Those descriptors are
+necessary to communicate with the checkpassword program. If you run
+qpsmtpd as some other user, adjust the sudo lines approriately.
+
+Using sudo is preferable to enabling setuid on the vchkpw binary. If
+you reinstall vpopmail and the setuid bit is lost, this plugin will be
+broken.
+
+=head1 DIAGNOSTICS
+
+Is the path in the config/smtpauth-checkpassword correct?
+
+Is the path to true in config/smtpauth-checkpassword correct?
+
+Is qpsmtpd running as the qpsmtpd user? If not, did you adjust the
+sudo configuration appropriately?
+
+If you are not using sudo, did you remember to make the vchkpw binary
+setuid (chmod 4711 ~vpopmail/bin/vchkpw)?
+
+While writing this plugin, I first wrote myself a little test script,
+which helped me identify the sudo closefrom_override issue. Here is
+that script:
+
+ #!/usr/bin/perl
+ use strict;
+ my $sudo = "/usr/local/bin/sudo";
+ $sudo .= " -C4 -u vpopmail";
+ my $vchkpw = "/usr/local/vpopmail/bin/vchkpw";
+ my $true   = "/usr/bin/true";
+
+ open(CPW,"|$sudo $vchkpw $true 3<&0");
+ printf(CPW "%s\0%s\0Y123456\0",'user@example.com','pa55word');
+ close(CPW);
+
+ my $status = $?;
+ print "FAIL\n" and exit if ( $status != 0 );
+ print "OK\n";
+
+Save that script to vchkpw.pl and then run it as the same user that
+qpsmtpd runs as:
+
+  setuidgid qpsmtpd perl vchkpw.pl
+
+If you aren't using sudo, then remove $sudo from the open line.

+This module supports PLAIN, LOGIN, and CRAM-MD5 authentication methods. You
+can disable undesired methods by editing this module and uncommenting
 the lines in the register() sub.  See the POD for Qspmtpd::Auth for more
 details on the ramifications of supporting various authentication methods.
-Then, change the database information at the top of the authsql() sub so that
-the module can access the database.  This can be a read-only account since 
-the plugin does not update the last accessed time (yet, see below).

+account name and domain), even if they don't normally need to.  This is
 because the vpopmail table has a unique index on pw_name/pw_domain, and this
 module requires that only a single record be returned from the database.
 
+=head1 LIMITATIONS
+
+This authentication modules does not recognize domain aliases. So, if you have
+the domain example.com, with domain aliases for example.org and example.net,
+smtp-auth will only work for $user@example.com. If you have domain aliases,
+consider using the auth_checkpassword plugin.
+
+The checkpassword plugin only supports plain and login authentications, where
+this plugin also supports CRAM-MD5. I use both modules together. I use this one
+for CRAM-MD5 and the checkpassword plugin for plain and login.

+=head1 VPOPMAIL
+
+There are 4 authentication (smtp-auth) plugins that can be used with
+vpopmail.
+
+=over 4
+
+=item auth_vpopmaild
+
+If you aren't sure which one to use, then use auth_vpopmaild. It
+has full support for all 3 authentication methods (PLAIN,LOGIN,CRAM-MD5),
+doesn't require the qpsmtpd process to run with special permissions, and
+can authenticate against vpopmail running on another host. It does require
+the vpopmaild server to be running.
+
+=item auth_vpopmail
+
+The next best solution is auth_vpopmail. It requires the p5-vpopmail perl
+module and it compiles against libvpopmail.a. There are two catches. The
+qpsmtpd daemon must run as the vpopmail user, and you must be running v0.09
+or higher for CRAM-MD5 support. The released version is 0.08 but my
+CRAM-MD5 patch has been added to the developers repo:
+   http://github.com/sscanlon/vpopmail
+
+=item auth_vpopmail_sql
+
+If you are using the MySQL backend for vpopmail, then this module can be
+used for smtp-auth. It has support for all three auth methods. However, it
+does not work with some vpopmail features such as alias domains, service
+restrictions, nor does it update vpopmail's last_auth information.
+
+=item auth_checkpassword
+
+The auth_checkpassword is a generic authentication module that will work
+with any DJB style checkpassword program, including ~vpopmail/bin/vchkpw.
+It only supports PLAIN and LOGIN auth methods.

+=head1 DESCRIPTION
+
+Sender Policy Framework (SPF) is an e-mail validation system designed to prevent spam by addressing source address spoofing. SPF allows administrators to specify which hosts are allowed to send e-mail from a given domain by creating a specific SPF record in the public DNS. Mail exchangers then use the DNS to check that mail from a given domain is being sent by a host sanctioned by that domain's administrators. -- http://en.wikipedia.org/wiki/Sender_Policy_Framework
+
+=head1 CONFIGURATION
+
+In config/plugins, add arguments to the sender_permitted_from line.
 
   sender_permitted_from spf_deny 1
 
-Other arguments are 'trust 0' and 'guess 0'. These turn off processing of 
-spf.trusted-forwarders.org and the best_guess functionality. It is unlikely 
-that you want to turn these off.
+=head2 spf_deny
 
-Adding 'spf_deny 2' will also issue a 5xx on a softfail response.
-
-You can also specify local SPF policy with 
-
-    include '<spf mechanism list>'
+Setting spf_deny to 0 will prevent emails from being rejected, even if they fail SPF checks. sfp_deny 1 is the default, and a reasonable setting. It temporarily defers connections (4xx) that have soft SFP failures and only rejects (5xx) messages when the sending domains policy suggests it. Settings spf_deny to 2 is more aggressive and will cause soft failures to be rejected permanently.

Subject: [PATCH 0986/1467] add TCPLOCAL* variables to $qp->connection

(patch remade against latest rspier/qpsmtpd)

added remote_port, local_ip, local_port, and local_host to $qp->connection, as the p0f plugin relies on it.
added notes to TcpServer.pm and the p0f plugin noting the dependence, and the lack of support for models other than tcpserver.

Subject: [PATCH 0987/1467] added local_ip option to p0f plugin

(updated patch against rspier/qpsmtpd)

The p0f plugin defaulted to binding to TCPLOCALIP, which doesn't work
when the mail server is running behind a firewall with a private IP. If
the local_ip option is set in the config file, it overrides TCPLOCALIP.

Added POD documentation for local_ip option and p0f general usage

-    chown qpsmtpd /tmp/.p0f_socket
+=head1 SYNOPSIS
 
-and add 
+Use TCP fingerprint info (remote computer OS, network distance, etc) to
+implement more sophisticated anti-spam policies.
+
+=head1 DESCRIPTION
+
+This p0f module inserts a 'p0f' note that other qpsmtpd plugins can inspect.
+It includes the following information about the TCP fingerprint (link,
+detail, distance, uptime, genre). Here's an example connection note:
+
+ genre    => FreeBSD
+ detail   => 6.x (1)
+ uptime   => 1390
+ link     => ethernet/modem
+ distance => 17
+
+Which was parsed from this p0f fingerprint:
+
+  24.18.227.2:39435 - FreeBSD 6.x (1) (up: 1390 hrs)
+    -> 208.75.177.101:25 (distance 17, link: ethernet/modem)
+
+=head1 MOTIVATION
+
+This p0f plugin provides a way to make sophisticated policies for email
+messages. For example, the vast majority of email connections to my server
+from Windows computers are spam (>99%). But, I have a few clients that use
+Exchange servers so I can't just block email from all Windows computers.
+
+Same goes for greylisting. Finance companies (AmEx, BoA, etc) just love to
+send notices that they won't queue and retry. Either they deliver at that
+instant or never. When I enable greylisting, I lose valid messages. Grrr.
+
+So, while I'm not willing to use greylisting, and I'm not willing to block
+connections from Windows computers, I am quite willing to greylist all email
+from Windows computers.
+
+=head1 CONFIGURATION
+
+Create a startup script for PF that creates a communication socket when your
+server starts up.
+
+ p0f -u qpsmtpd -d -q -Q /tmp/.p0f_socket 'dst port 25' -o /dev/null
+ chown qpsmtpd /tmp/.p0f_socket
+
+add an entry to config/plugins to enable p0f:
 
  ident/p0f /tmp/.p0f_socket 
 
-to config/plugins
+=head2 local_ip
 
-it puts things into the 'p0f' connection notes so other plugins can do
-things based on source OS.
+Use the local_ip option to override the IP address of your mail server. This
+is useful if your mail server has a private IP because it is running behind
+a firewall. For example, my mail server has the IP 127.0.0.6, but the world
+knows my mail server as 208.75.177.101.
+
+Example config/plugins entry with local_ip override:

Subject: [PATCH 0988/1467] added p0f support to greylist plugin

- these changes are in the previous TCPLOCAL patch. Documented here.
added p0f config option
added POD docs to explain usage
modified $dbdir selection logic. The previous logic failed when QPHOME was
 not selected (as is the case when tests are being run).
Added '.' as the dir of last resort for $dbdir selection (others $EMPTY/dir
 dumped greylisting database in / )

  - These changes are included in this patch -
Added t/plugin_tests/greylisting, with greylist logic testing (tests are
 disabled by default, as greylisting is disabled in config.sample/plugins)
Added example entry in config.sample/plugins

Subject: [BUG] Default search path used in require_resolvable_fromhost
Date: Sat, 17 Jul 2010 16:24:42 -0400 (EDT)
Message-ID:
 <Pine.LNX.4.64.1007171623040.17109@e-smith.charlieb.ott.istop.com>

http://bugs.contribs.org/show_bug.cgi?id=5808

 Jesper Knudsen      2010-03-01 01:29:10 MST

When using the require_resolvable_fromhost plugin for qpsmtpd I noticed
that mails from user@localhost.localdomain was actually getting through
this filter. I finally found out that the plugin has a bug that causes it
to insert default search path if it cannot find the domain. This means in
my case that localhost.localdomain was then tried resolved as
localhost.localdomain.swerts-knudsen.dk and since I have a wilcard CNAME
was resolved as my public IP.

Since this plugin is only enabled for public interface the fix is to set
the "dnsrch" flag when creating the Net::DNS object.

In require_resolvable_fromhost:
my $res = Net::DNS::Resolver->new (
                                   dnsrch => 0
                                   );

Subject: [PATCH 0999/1467] Shorten/clarify Connection and Transaction notes()

Update Qpsmtpd::Connection::notes() and Qpsmtpd::Transaction::notes()
with clearer, more brief syntax.  A previous patch used seemingly better
syntax, but did not evaluate the size of @_ in order to distinguish
between a call to notes('arg1',undef) and notes('arg1').  This corrects
this issue, and adds a comment to that effect.

This makes hook_reset_transaction a bit more useful by running it on

Subject: [PATCH 1001/1467] Add support for multiple postfix cleanup sockets

The current postfix-queue plugin allows the administrator to set a
single path to a local postfix cleanup socket file from the plugin
'command line'.  This adds a 'cleanup_sockets' configuration directive
that can contain a list of paths as well as host/port combinations
pointing to postfix cleanup services, which will be tried in the order
that they appear.  Not yet tested.

Subject: [PATCH 1004/1467] new plugin rcpt_map

Check recipients from a postfix style map. The valid return codes are of course
qpsmtpd constants. By storing the addresses in a %hash, this is much faster
for fixed addresses than using the rcpt_regexp plugin just with fixed strings.
This plugin handles only one domain per plugin instance. Use the :N suffix for
the plugin if you need several domains mapped.

+=head1 NAME
+
+rcpt_map - check recipients against recipient map
+
+=head1 DESCRIPTION
+
+B<rcpt_map> reads a list of adresses, return codes and comments
+from the supplied config file. Adresses are compared with I<eq lc($rcpt)>.
+The recipient addresses are checked against this list, and if the first 
+matches, the return code from that line and the comment are returned to
+qpsmtpd. Return code can be any valid plugin return code from 
+L<Qpsmtpd::Constants>. Matching is always done case insenstive. 
+
+=head1 ARGUMENTS
+
+The C<file MAP> and C<domain NAME> arguments are required. The default value of
+the C<default> argument is C<DENY=No_such_user.> (see below why C<_>).
+
+=over 4
+
+=item domain NAME
+
+If the recipient address does not match this domain name NAME, this plugin will
+return C<DECLINED>
+
+=item file MAP
+
+Use the config file as map file, format as explained below
+
+=item default CODE[=MSG]
+
+Use CODE as default return code (and return MSG as message) if a recipient 
+was B<not> found in the map. Since we can't use spaces in MSG, every C<_>
+is replaced by a space, i.e. use C<DENY=User_not_found> if you want a deny
+message C<User not found>.
+
+=back
+
+=head1 CONFIG FILE
+
+The config file contains lines with an address, a return code and a comment, 
+which will be returned to the sender, if the code is not OK or DECLINED. 
+Example:
+
+  # example_org_map - config for rcpt_map plugin
+  me@example.org           OK 
+  you@example.org          OK 
+  info@example.org         DENY     User not found.
+
+=head1 NOTES 
+
+We're currently running this plugin like shown in the following example. 
+
+Excerpt from the C<plugins> config file:
+
+  ## list of valid users, config in /srv/qpsmtpd/config/rcpt_regexp
+  ## ... except for "*@example.org":
+  rcpt_regexp
+  ## only for "@example.org":
+  rcpt_map domain example.org file /srv/qpsmtpd/config/map_example_org
+
+And the C<rcpt_regexp> config file:
+
+ ### "example.org" addresses are checked later by the rcpt_map 
+ ### plugin, return DECLINED here:
+ /^.*\@example\.org$/  DECLINED
+ ### all other domains just check for valid users, the validity 
+ ### of the domain is checked by the rcpt_ok plugin => never use
+ ### something else than "DENY" or "DECLINED" here!
+ /^(abuse|postmaster)\@/    DECLINED
+ /^(me|you)\@/    DECLINED
+ /^.*$/           DENY No such user.

We have to return something true, else the client gets an additional

Subject: [PATCH 1010/1467] temp_resolver_failed is a transaction note

 The mail hook sets a transaction note 'temp_resolver_failed', but the
 rcpt hook queried a connection note of the same name (which didn't
 exist, of course).
 Now it queries the transaction note.

Subject: [PATCH 1012/1467] fixed failing auths to auth/vpopmaild, added tests

Apparently the format of vpopmaild responses has been expanded and the responses
are conditional.

* Replaced the 'sometimes works' eq comparison with a regexp that always works.
* added tests for all 3 vpopmail plugins
* added cram-md5 auth support to auth_vpopmaild.

From dbaa9dbd6c9bed3a079651e89feba24f941435ec Mon Sep 17 00:00:00 2001
From: Matt Simerson <matt@tnpi.net>
Date: Sat, 7 Apr 2012 20:11:16 -0400
Subject: [PATCH 1027/1467] POD corrections, additional tests, plugin
 consistency

on files in plugins dir:
  fixed a number of POD errors

  formatted some # comments into POD

  removed bare 1;  (these are plugins, not perl modules)
    most instances of this were copy/pasted from a previous plugin that had it

  removed instances of # vim ts=N ...
    they weren't consistent, many didn't match .perltidyrc

  on modules that failed perl -c tests, added 'use Qpsmtpd::Constants;'

Conflicts:

+=head1 NAME
+
+dspam - dspam integration for qpsmtpd
+
+=head1 DESCRIPTION
+
+qpsmtpd plugin that uses dspam to classify messages. Can use SpamAssassin to 
+train dspam.
+
+Adds the X-DSPAM-Result and X-DSPAM-Signature headers to messages. The latter is essential for 
+training dspam and the former is useful to MDAs, MUAs, and humans.
+
+=head1 TRAINING DSPAM
+
+To get dspam into a useful state, it must be trained. The best method way to
+train dspam is to feed it two large equal sized corpuses of spam and ham from
+your mail server. The dspam authors suggest avoiding public corpuses. I do
+this as follows:
+
+=over 4
+
+=item learn from SpamAssassin
+
+See the docs on the learn_from_sa feature in the CONFIG section.
+
+=item daily training
+
+I have a script that crawls the contents of every users maildir each night.
+The script builds two lists of messages: ham and spam. 
+
+The spam message list consists of all read messages in folders named Spam
+that have changed since the last spam learning run (normally 1 day).
+
+The ham message list consists of read messages in any folder not named like
+Spam, Junk, Trash, or Deleted. This catches messages that users have read 
+and left in their inbox, filed away into subfolders, and 
+
+=item on-the-fly training
+
+=back
+
+
+
+=head1 CONFIG
+
+=over 4
+
+=item dspam_bin
+
+The path to the dspam binary. If yours is installed somewhere other 
+than /usr/local/bin/dspam, you'll need to set this.
+
+=item learn_from_sa
+
+Dspam can be trained by SpamAssassin. This relationship between them requires
+attention to several important details:
+
+=over 4
+
+=item 1
+
+dspam must be listed B<after> spamassassin in the config/plugins file. 
+Because SA runs first, I crank the SA reject_threshold up above 100 so that
+all spam messages will be used to train dspam.
+
+Once dspam is trained and errors are rare, I plan to run dspam first and
+reduce the SA load.
+
+=item 2
+
+Autolearn must be enabled and configured in SpamAssassin. SA autolearn
+preferences will determine whether a message is learned as spam or innocent
+by dspam. The settings to pay careful attention to in your SA local.cf file 
+are bayes_auto_learn_threshold_spam and bayes_auto_learn_threshold_nonspam.
+Make sure they are both set to conservative values that are certain to 
+yield no false positives.
+
+If you are using learn_from_sa and reject, then messages that exceed the SA
+threshholds will cause dspam to reject them. Again I say, make sure them SA
+autolearn threshholds are set high enough to avoid false positives.
+
+=item 3
+
+dspam must be configured and working properly. I have modified the following
+dspam values on my system: 
+
+=over 4
+
+=item mysql storage
+
+=item Trust smtpd
+
+=item TrainingMode tum
+
+=item Tokenizer osb
+
+=item Preference "trainingMode=TOE"
+
+=item Preference "spamAction=deliver"
+
+=item Preference "signatureLocation=headers"
+
+=item TrainPristine off
+
+=item ParseToHeaders off
+
+=back
+
+Of those changes, the most important is the signature location. This plugin
+only supports storing the signature in the headers. If you want to train dspam
+after delivery (ie, users moving messages to/from spam folders), then the
+dspam signature must be in the headers.
+
+=back
+
+=item reject
+
+Set to a floating point value between 0 and 1.00 where 0 is no confidence
+and 1.0 is 100% confidence.
+
+If dspam's confidence is greater than or equal to this threshold, the 
+message will be rejected.
+
+=back
+
+
+=head1 MULTIPLE RECIPIENT BEHAVIOR
+
+For messages with multiple recipients, the user that dspam is running as will
+be the dspam username.
+
+When messages have a single recipient, the recipient address is used as the
+dspam username. For dspam to trust qpsmtpd with modifying the username, you
+B<must> add the username that qpsmtpd is running to to the dspamd.conf file.
+
+ie, (Trust smtpd).

Exclude some tests with dependencies.

Remove -T from perl line in plugins
This makes it harder to test with PERL5LIB/perlbrew etc

Subject: [PATCH 1041/1467] spf: remove DENYSOFT on SPF softfail

With a DENYSOFT (450) the sender will keep trying to deliver the e-mail.
It makes no sense.

This commit also makes it compatible again with the plugin from before commit:

+=head1 FAQ
+
+=head2 Q: Do I need to enable a logging plugin?
+
+=head2 A: No.
+
+When zero logging plugins are configured, logs are directed to STDERR. This
+is the 'default' logging and logs are piped to multilog and stored in
+log/main/current.
+
+When more than zero logging plugins are enabled, builtin logging is disabled
+and logs are sent to every logging plugin configured in config/plugins.
+
+
+=head2 Q: How do I watch the logs?
+
+=head2 A: Here's a few examples:
+
+The default log files can be watched in real time lik this:
+
+ tail -F ~smtpd/log/main/current
+
+To convert the tai timestamps to human readable date time:
+
+ tail -F ~smtpd/log/main/current | tai64nlocal
+
+To exclude the dates entirely, use this command:
+
+ tail -F ~smtpd/smtpd/log/main/current | cut -d' ' -f2-3
+
+
+=head2 Q: How do I get alerts when qpsmtpd has a problem?
+
+=head2 A: Send logs with levels below LOGERROR to syslog.
+
+This can be done by adding the following lines to config/plugins:
+
+  logging/syslog loglevel LOGERROR
+  logging/warn LOGINFO
+
+The warn logging plugin replicates the builtin logging, directing log messages to STDERR. The syslog plugin directs errors to syslog where standard monitoring tools can pick them up and act on them.
+
+With these settings, errors will still get sent to STDERR as well.

+=head1 NAME
+
+auth_ldap_bind - Authenticate user via an LDAP bind
+
+=head1 DESCRIPTION
+
+This plugin authenticates users against an LDAP Directory.  The plugin
+first performs a lookup for an entry matching the connecting user.  This
+lookup uses the 'ldap_auth_filter_attr' attribute to match the connecting
+user to their LDAP DN.  Once the plugin has found the user's DN, the plugin
+will attempt to bind to the Directory as that DN with the password that has
+been supplied.
+
+=head1 CONFIGURATION
+
+Configuration items can be held in either the 'ldap' configuration file, or as
+arguments to the plugin.
+
+Configuration items in the 'ldap' configuration file
+are set one per line, starting the line with the configuration item key,
+followed by a space, then the values associated with the configuration item.
+
+Configuration items given as arguments to the plugin are keys and values
+separated by spaces.  Be sure to quote any values that have spaces in them.
+
+The only configuration item which is required is 'ldap_base'.  This tells the
+plugin what your base DN is.  The plugin will not work until it has been
+configured.
+
+The configuration items 'ldap_host' and 'ldap_port' specify the host and port
+at which your Directory server may be contacted.  If these are not specified,
+the plugin will use port '389' on 'localhost'.
+
+The configuration item 'ldap_timeout' specifies how long the plugin should
+wait for a response from your Directory server.  By default, the value is 5
+seconds.
+
+The configuration item 'ldap_auth_filter_attr' specifies how the plugin should
+find the user in your Directory.  By default, the plugin will look up the user
+based on the 'uid' attribute.
+
+=head1 NOTES
+
+Each auth requires an initial lookup to find the user's DN.  Ideally, the
+plugin would simply bind as the user without the need for this lookup (see
+FUTURE DIRECTION below).
+
+This plugin requires that the Directory allow anonymous bind (see FUTURE
+DIRECTION below).
+
+=head1 FUTURE DIRECTION
+
+A configurable LDAP filter should be made available, to account for users
+who are over quota, have had their accounts disabled, or whatever other
+arbitrary requirements.
+
+A configurable DN template (uid=$USER,ou=$DOMAIN,$BASE).  This would prevent
+the need of the initial user lookup, as the DN is created from the template.
+
+A configurable bind DN, for Directories that do not allow anonymous bind.
+
+Another plugin ('ldap_auth_cleartext'?), to allow retrieval of plain-text
+passwords from the Directory, permitting CRAM-MD5 or other hash algorithm
+authentication.

Subject: [PATCH 1050/1467] in log entries, print hook name first

so log entries look like this:

86553 (connect) ident::geoip: US, United States
86553 (connect) ident::p0f: Windows 7 or 8
86553 (connect) check_earlytalker: remote host said nothing spontaneous, proceeding

instead of this:

86553 ident::geoip: (connect): US, United States
86553 ident::p0f: (connect) Windows 7 or 8
86553 check_earlytalker: (connect): remote host said nothing spontaneous, proceeding

 =head1 SYNOPSIS
 
-  domainkeys [warn_only 1]
+  domainkeys [reject 1]
 
-Performs a DomainKeys validation on the message.  Takes a single
-configuration
+Performs a DomainKeys validation on the message.
 
-  warn_only 1
+=head1 CONFIGURATION
 
-which means that messages which are not correctly signed (i.e. signed but
-modified or deliberately forged) will not be DENY'd, but an error will still
-be issued to the logfile.
+=head2 reject
+
+  reject 1
+
+Reject is a boolean that toggles message rejection on or off. Messages failing
+DomainKeys validation are rejected by default.
+
+=head2 reject_type
+
+  reject_type [ temp | perm ]
+
+The default rejection type is permanent.
+
+=head2 warn_only
+
+A deprecated option that disables message rejection. See reject instead.

Subject: [PATCH 1064/1467] spamassassin updates

refactored into small subs with unit tests.
parse SA header with split instead of regexp (more reliable)
store SA results in a 'spamassassin' transaction note
add strict and warnings pragma
renamed reject_threshold -> reject (backwards compatible)
added relayclient skip option and POD. Skips SA processing when relayclient is set
added MULTIPLE RECIPIENT BEHAVIOR topic to POD

+=head1 MULTIPLE RECIPIENT BEHAVIOR
+
+This plugin supports per-user SpamAssassin preferences. When per-user SA prefs
+are enabled (by setting spamd_user = vpopmail), the message recipient is used
+as the spamd username. If SpamAssassin has per-user preferences enabled, it
+will consult the users spam preferences when scoring the message.
+
+When a message has multiple recipients, we do not change the spamd username.
+The message is still scored by SA, but per-user preferences are not
+consulted. To aid in debugging, messages with multiple recipents will
+have an X-Spam-User header inserted. Admins and savvy users can look for
+that header to confirm the reason their personal prefs were not consulted.
+
+To get per-user SA prefs to work for messages with multiple recipients, the
+LDA should be configured to check for the presence of the X-Spam-User header.
+If the X-Spam-User header is present, the LDA should submit the message to
+spamd for re-processing with the recipients address.

+2012.04.02 - Matt Simerson
+
+  * refactored for ease of maintenance
+  * added support for per-user SpamAssassin preferences
+  * updated get_spam_results so that score=N.N works (as well as hits=N.N)
+  * rewrote the X-Spam-* header additions so that SA generated headers are
+    not discarded. Admin can alter SA headers with add_header in their SA
+    config. Subverting their changes there is unexpected. Making them read
+    code to figure out why is an unnecessary hurdle.

Subject: [PATCH 1065/1467] dspam: a batch of improvements:

expanded POD
cleaned up stray EOL spaces
added lots of logging, with standardized [ pass | fail | skip ] prefixes
added reject_type option
use split for parsing dspam headers
use SA note instead of parsing headers
added reject = agree option
store & fetch dspam results in a note

Subject: [PATCH 1067/1467] Altered SASL method to include the mechanism in log
 entries.

removed auth method from return calls in all auth plugins. The caller knows the mechanism already. In the code, the difference looks like this:

before:
        or return (DENY, "authcvm/$method");
after:
        or return (DENY, "authcvm");

Added debug level log entries in auth_vpopmaild

+=head1 NAME
+
+warn - Default logging plugin for qpsmtpd
+
+=head1 DESCRIPTION
+
+A qpsmtpd plugin which replicates the built in logging functionality, which
+is to send all logging messages to STDERR below a specific log level.
+
+It demonstrates that a logging plugin can call ->log itself as well
+as how to ignore log entries from itself
+
+=head1 INSTALL AND CONFIG
+
+Place this plugin in the plugin/logging directory beneath the standard
+qpsmtpd installation.  Edit the config/logging file and add a line like
+this:
+
+  logging/warn [loglevel]
+
+where the optional parameters C<loglevel> is either the numeric or text
+representation of the maximum log level, as shown in the
+L<config.sample/loglevel> file.

Subject: [PATCH 1086/1467] greylisting, refactored and many changes

fixed the vestiges of old plugin name 'denysoft_greylisting'

added ability to bypass greylisting based on geoip

deprecated 'mode [denysoft | testonly | off]
	off wasn't useful
	testonly & denysoft replaced by reject [ 0 | 1 ]

renamed DB from denysoft_greylist to greylist.dbm. Will use existing/legacy DB if present.

added DB pruning feature. Automatically prune the DB when qpsmtpd registers the plugin. Perhaps this should be a config option to enable?

added DB upgrade feature. Convert dotted quad IP addresses in DB to integers. Makes greylisting IPv6 compatible, since DB records are colon delimited.

exempt TLS connections from greylisting. The vast majority (perhaps all) of the SMTP clients that request encryption to my server are legit. We could add a config option for this, but this plugin already has a multitude of config options.

refactored much of the greylisting method into discreet subs

added 30 tests

added additional DEBUG level logging for p0f matches

POD changes:
	replaced over, item N, back, with head2 (better formatted output)
	better describe the current behavior of the plugin (some past behaviors no longer exist)
	added TRIPLET section with example
	added loglevel section

 =head1 NAME
 
-denysoft_greylist
+greylisting - delay mail from unknown senders
 
 =head1 DESCRIPTION
 
-Plugin to implement the 'greylisting' algorithm proposed by Evan 
-Harris in http://projects.puremagic.com/greylisting/. Greylisting is 
-a form of denysoft filter, where unrecognised new connections are 
-temporarily denied for some initial period, to foil spammers using 
+Plugin implementing the 'greylisting' algorithm proposed by Evan
+Harris in http://projects.puremagic.com/greylisting/. Greylisting is
+a form of denysoft filter, where unrecognised new connections are
+temporarily denied for some initial period, to foil spammers using
 fire-and-forget spamware, http_proxies, etc.
 
-Greylisting adds two main features: it tracks incoming connections 
-using a triplet of remote IP address, sender, and recipient, rather 
-than just using the remote IP; and it uses a set of timeout periods 
-(black/grey/white) to control whether connections are allowed, instead 
-of using connection counts or rates.
+Greylisting tracks incoming connections using a triplet (see TRIPLET). It
+has configurable timeout periods (black/grey/white) to control whether
+connections are allowed, instead of using connection counts or rates.
 
-This plugin allows connection tracking on any or all of IP address, 
-sender, and recipient (but uses IP address only, by default), with 
-configurable greylist timeout periods. A simple dbm database is used 
-for tracking connections, and relayclients are always allowed 
-through. The plugin supports whitelisting using the whitelist_soft
-plugin (optional).
+Automatic whitelisting is enabled for relayclients, whitelisted hosts,
+whitelisted senders, TLS connections, p0f matches, and geoip matches.
 
+=head1 TRIPLETS
+
+In greylisting, I<remote_ip>, I<sender>, and I<recipient> are referred to
+as the triplet that connections are deferred based on. This plugin allows
+tracking on any or all of the three, using only the IP address by default.
+A simple dbm database is used for tracking connections.
+
+How that works is best explained by example:
+
+A new connection arrives from the host shvj1.jpmchase.com. The sender is
+chase@alerts.chase.com and the recipient is londonwhale@example.com. This is
+the first connection for that triplet so the connection is deferred for
+I<black_timeout> minutes. After the timeout, but before the I<grey_timeout>
+elapses, shvj1.jpmchase.com retries and successfully delivers the mail. For
+the next I<white_timeout> days, emails for that triplet are not delayed.
+
+The next day, shvj1.jpmchase.com tries to deliver a new email from
+alerts@alerts.chase.com to jdimon@example.com. Since this triplet is new, it
+will be delayed as our initial connection in the last scenario was. This
+delay could end up costing over US $4B.
+
+By default, this plugin does not enable the sender or recipient in the triplet.
+Once an email from a remote server has been delivered to anyone on our server,
+that remote server is whitelisted for any sender and any recipient. This is a
+policy that delays less mail and is less likely to impoverish your bank.

Subject: [PATCH 1089/1467] consolidate auth logic into Qpsmtpd::Auth

These 3 auth plugins all have a data store they fetch the reference
password or hash from. They then match the attemped password or hash
against the reference. This consolidates the latter portion (validating
the password/hash) into Auth.pm.

* less duplicated code in the plugins.
* Pass validation consistently handled for these 3 plugins.
* less work to create new auth plugins

Also caches the CRAM-MD5 ticket. It could also cache user/pass info if
this was desirable.

 The B<hosts_allow> module decides before the SMTP-Greeting if a host is
 allowed to connect. It checks for too many (running) connections from one

-The config file contains lines with two or three items. The first is either
-an IP address or a network/mask pair. The second is a (valid) return code

-connecting client if the return code is DENY or DENYSOFT (and of course 
-DENY_DISCONNECT and DENYSOFT_DISCONNECT).

+
+To get similar functionality for the tcpserver deployment model, use

+=head1 SYNOPSIS
+
+deny connections to recipients in the I<badrcptto> file
+
+like badmailfrom, but for recipient address rather than sender
+
+=head1 CONFIG
+
+Recipients are matched against entries in I<config/badrcptto>. Entries can be
+a complete email address, a host entry that starts with an @ symbol, or a
+regular expression. For regexp pattern matches, see PATTERNS.
+
+=head1 PATTERNS
+
+This allows special patterns to be denied (e.g. percent hack, bangs,
+double ats).
+
+Patterns are stored in the format pattern\sresponse, where pattern
+is a Perl pattern expression. Don't forget to anchor the pattern if
+you want to restrict it from matching anywhere in the string.
+
+qpsmtpd already ensures that the address contains an @, with something
+to the left and right of the @.

Subject: [PATCH 1110/1467] SPF plugin: refactored, tests, new config option

added POD description of spfquery note

changed spf_deny -> reject  (and offered 4 more options, see POD for reject)
	backwards compatible with old config settings
	replicates qmail-smtpd SPF patch behavior

improved logging (again)

uses a stringy eval 'use Mail::SPF' in the register sub. If missing, warn and log the error, and don't register any hooks. This is much nicer error than the current, "*** Remote host closed connection unexpectedly." broken mail server that results from enabling the SPF plugin without Mail::SPF installed.

background: I noticed I was deferring valid emails with the SPF plugin at 'spf_deny 1', and without changing the code, there wasn't a way to change how ~all records were handled. This provides that flexibility.

 Sender Policy Framework (SPF) is an e-mail validation system designed to prevent spam by addressing source address spoofing. SPF allows administrators to specify which hosts are allowed to send e-mail from a given domain by creating a specific SPF record in the public DNS. Mail exchangers then use the DNS to check that mail from a given domain is being sent by a host sanctioned by that domain's administrators. -- http://en.wikipedia.org/wiki/Sender_Policy_Framework
 
+The results of a SPF query are stored in a transaction note named 'spfquery';
+
 =head1 CONFIGURATION
 
 In config/plugins, add arguments to the sender_permitted_from line.
 
-  sender_permitted_from spf_deny 1
+  sender_permitted_from reject 3
 
-=head2 spf_deny
+=head2 reject
 
-Setting spf_deny to 0 will prevent emails from being rejected, even if they fail SPF checks. sfp_deny 1 is the default, and a reasonable setting. It temporarily defers connections (4xx) that have soft SFP failures and only rejects (5xx) messages when the sending domains policy suggests it. Settings spf_deny to 2 is more aggressive and will cause soft failures to be rejected permanently.
+Set to a value between 1 and 6 to enable the following SPF behaviors:
 
-See also http://spf.pobox.com/
+ 1 annotate-only, add Received-SPF header, no rejections.
+ 2 defer on DNS failures. Assure there's always a meaningful SPF header.
+ 3 rejected if SPF record says 'fail'
+ 4 stricter reject. Also rejects 'softfail'
+ 5 reject 'neutral'
+ 6 reject if no SPF records, or a syntax error
+
+Most sites should start at level 3. It temporarily defers connections (4xx) that have soft SFP failures and only rejects (5xx) messages when the sending domains policy suggests it.
+
+SPF levels above 4 are for crusaders who don't mind rejecting some valid mail when the sending server administrator hasn't dotted his i's and crossed his t's. May the deities bless theirobsessive little hearts.

+=head1 qpsmtpd logging; user documentation
+
+Qpsmtpd has a modular logging system. Here's a few things you need to know:
+
+ * The built-in logging prints log messages to STDERR.
+ * A variety of logging plugins is included, each with its own behavior.
+ * When a logging plugin is enabled, the built-in logging is disabled.
+ * plugins/logging/warn mimics the built-in logging.
+ * Multiple logging plugins can be enabled simultaneously.
+
+Read the POD within each logging plugin (perldoc plugins/logging/B<NAME>)
+to learn if it tickles your fancy.
+
+=head2 enabling plugins
+
+To enable logging plugins, edit the file I<config/logging> and uncomment the
+entries for the plugins you wish to use.
+
+=head2 logging level
+
+The 'master switch' for loglevel is I<config/loglevel>. Qpsmtpd and active
+plugins will output all messages that are less than or equal to the value
+specified. The log levels correspond to syslog levels:
+
+    LOGDEBUG   = 7
+    LOGINFO    = 6
+    LOGNOTICE  = 5
+    LOGWARN    = 4
+    LOGERROR   = 3
+    LOGCRIT    = 2
+    LOGALERT   = 1
+    LOGEMERG   = 0
+    LOGRADAR   = 0
+
+Level 6, LOGINFO, is the level at which most servers should start logging. At
+level 6, each plugin should log one and occasionally two entries that
+summarize their activity. Here's a few sample lines:
+
+ (connect) ident::geoip: SA, Saudi Arabia
+ (connect) ident::p0f: Windows 7 or 8
+ (connect) earlytalker: pass: remote host said nothing spontaneous
+ (data_post) domainkeys: skip: unsigned
+ (data_post) spamassassin: pass, Spam, 21.7 < 100
+ (data_post) dspam: fail: agree, Spam, 1.00 c
+ 552 we agree, no spam please (#5.6.1)
+
+Three plugins fired during the SMTP connection phase and 3 more ran during the
+data_post phase. Each plugin emitted one entry stating their findings.
+
+If you aren't processing the logs, you can save some disk I/O by reducing the
+loglevel, so that the only messages logged are ones that indicate a human
+should be taking some corrective action.
+
+=head2 log location
+
+If qpsmtpd is started using the distributed run file (cd ~smtpd; ./run), then
+you will see the log entries printed to your terminal. This solution works
+great for initial setup and testing and is the simplest case.
+
+A typical way to run qpsmtpd is as a supervised process with daemontools. If
+daemontools is already set up, setting up qpsmtpd may be as simple as:
+
+C<ln -s /usr/home/smtpd /var/service/>
+
+If svcscan is running, the symlink will be detected and tcpserver will
+run the 'run' files in the ./ and ./log directories. Any log entries
+emitted will get handled per the instructions in log/run. The default
+location specified in log/run is log/main/current.
+
+=head2 plugin loglevel
+
+Most plugins support a loglevel argument after their config/plugins entry.
+The value can be a whole number (N) or a relative number (+/-N), where
+N is a whole number from 0-7. See the descriptions of each below.
+
+C<ident/p0f loglevel 5>
+
+C<ident/p0f loglevel -1>
+
+ATTN plugin authors: To support loglevel in your plugin, you must store the
+loglevel settings from the plugins/config entry $self->{_args}{loglevel}. A
+simple and recommended example is as follows:
+
+ sub register {
+   my ( $self, $qp ) = shift, shift;
+   $self->log(LOGERROR, "Bad arguments") if @_ % 2;
+   $self->{_args} = { @_ };
+ }
+
+=head3 whole number
+
+If loglevel is a whole number, then all log activity in the plugin is logged
+at that level, regardless of the level the plugin author selected. This can
+be easily understood with a couple examples:
+
+The master loglevel is set at 6 (INFO). The mail admin sets a plugin loglevel
+to 7 (DEBUG). No messages from that plugin are emitted because DEBUG log
+entries are not <= 6 (INFO).
+
+The master loglevel is 6 (INFO) and the plugin loglevel is set to 5 or 6. All
+log entries will be logged because 5 is <= 6.
+
+This behavior is very useful to plugin authors. While testing and monitoring
+a plugin, they can set the level of their plugin to log everything. To return
+to 'normal' logging, they just update their config/plugins entry.
+
+=head3 relative
+
+Relative loglevel arguments adjust the loglevel of each logging call within
+a plugin. A value of I<loglevel +1> would make every logging entry one level
+less severe, where a value of I<loglevel -1> would make every logging entry
+one level more severe.
+
+For example, if a plugin has a loglevel setting of -1 and that same plugin
+logged a LOGDEBUG, it would instead be a LOGINFO message. Relative values
+makes it easy to control the verbosity and/or severity of individual plugins.

+
+Normal ip based dns blocking lists ("RBLs") which contain TXT records are

To get the equivalent functionality of enabling 'relay_only', use the 'only' argument to the relay plugin as documented in the RELAY ONLY section of plugins/relay.

 GREYLISTING plugin:
 
     'mode' config argument is deprecated. Use reject and reject_type instead.

 =head1 NAME
 
-check_basicheaders - Make sure both From and Date headers are present, and
-do optional range checking on the Date header.
+check_basicheaders
 
 =head1 DESCRIPTION
 
-Rejects messages that do not have a From or Date header or are completely
-empty.
+Checks for missing or empty values in the From or Date headers.
 
-Can also reject messages where the date in the Date header is more than
-some number of the days in the past or future.
+Optionally test if the Date header is too many days in the past or future. If
+I<future> or I<past> are not defined, they are not tested.
 
 =head1 CONFIGURATION
 
-The following optional parameters exist:
+The following optional settings exist:
+
+=head2 future
+
+The number of days in the future beyond which messages are invalid.
+
+  check_basicheaders [ future 1 ]
+
+=head2 past
+
+The number of days in the past beyond which a message is invalid. The Date header is added by the MUA, so there are many valid reasons a message may have an older date in the header. It could have been delayed by the client, the sending server, connectivity problems, recipient server problem, recipient server configuration, etc. The I<past> setting should take those factors into consideration.
+
+I would be surprised if a valid message ever had a date header older than a week.
+
+  check_basicheaders [ past 5 ]
 
 =head2 days
 
-The number of days in the future or past beyond which to reject messages. When
-unset, messages are not rejected based on the date.
+Deprecated. Use I<past> and I<future> instead.
+
+The number of days in the future or past beyond which messages are invalid.
 
   check_basicheaders [ days 3 ]
 
+=head2 reject
+
+Determine if the connection is denied. Use the I<reject 0> option when first enabling the plugin, and then watch your logs to see what would have been rejected. When you are no longer concerned that valid messages will be rejected, enable with I<reject 1>.
+
+  check_basicheaders [ reject 0 | 1 ]
+
+Default policy is to reject.
+
 =head2 reject_type
 
 Whether to issue a permanent or temporary rejection. The default is permanent.
 
   check_basicheaders reject_type [ temp | perm ]
 
-Switching to a temporary rejection is most useful when testing the plugin. It
-allows an administrator to watch for a test period and make sure no valid mail
-is getting rejected.
+Using a temporary rejection is a cautious way to enable rejections. It allows an administrator to watch for a trial period and assure no valid messages are rejected. If a deferral of valid mail is noticed, I<reject 0> can be set to permit the deferred message to be delivered.
+
+Default policy is a permanent rejection.
+
+=head2 loglevel
+
+Adjust the quantity of logging for this plugin. See docs/logging.pod

     All 3 plugins are deprecated and replaced with a new 'relay' plugin. The new plugin reads the same config files (see 'perldoc plugins/relay') as the previous plugins. To get the equivalent functionality of enabling 'relay_only', use the 'only' argument to the relay plugin as documented in the RELAY ONLY section of plugins/relay.

+=head1 NAME
+
+resolvable_fromhost
+
+=head1 SYNOPSIS
+
+Determine if the from host resolves to a valid MX or host.
+
+=head1 DESCRIPTION
+
+The fromhost is the part of the email address after the @ symbol, provided by
+the sending server during the SMTP conversation. This is usually, but not
+always, the same as the hostname in the From: header.
+
+B<resolvable_fromhost> tests to see if the fromhost resolves. It saves the 
+results in the transaction note I<resolvable_fromhost> where other plugins can
+use that information. Typical results are:
+
+ a  - fromhost resolved as an A record
+ mx - fromhost has valid MX record(s)
+ ip - fromhost was an IP
+ whitelist - skipped checks due to whitelisting
+ null - null sender
+ config - fromhost not resolvable, but I<reject 0> was set.
+
+Any other result is an error message with details of the failure.
+
+If B<resolvable_fromhost> is enabled, the from hostname is also stored in
+I<resolvable_fromhost_host>, making it accessible when $sender is not.
+
+=head1 CONFIGURATION
+
+=head2 reject <bool>
+
+If I<reject 1> is set, the old require_resolvable_fromhost plugin behavior of
+temporary rejection is the default.
+
+ resolvable_fromhost reject [ 0 | 1 ]
+
+Default: 1
+
+=head2 reject_type
+
+ reject_type [ perm | temp ]
+
+Set I<reject_type perm> to reject mail instead of deferring it.
+
+Default: temp (temporary, aka soft, aka 4xx).
+

added 23 tests

deprecate action argument
	'action log' did nothing, better logging controls available with loglevel
	'action deny'  ->  reject 1
	'action denysoft' =>  reject 1 reject_type temp

use head2 for config options (instead of over, item, back)
added loglevel section

-
-=head1 SYNOPSIS
-
-This plugin checks the norelayclients config file to see if 
-relaying is denied.
-
-This allows specific clients, such as the gateway, to be denied 
-relaying, even though they would be allowed relaying by the 
-relayclients file.
-
-=head1 CONFIG
-
-config/norelayclients
-
-Each line is:
-- a full IP address
-- partial IP address terminated by a dot for matching whole networks
-  e.g. 192.168.42.
-
-=head1 BUGS AND LIMITATIONS
-
-This plugin does not have a more_norelayclients map equivalent
-of the more_relayclients map of the check_relay plugin.
-
-=head1 AUTHOR
-
-Based on check_relay plugin from the qpsmtpd distribution.

+=head1 SYNOPSIS
+
+relay - control whether relaying is permitted
+
+=head1 DESCRIPTION
+
+relay - check the following places to see if relaying is allowed:
+
+I<$ENV{RELAYCLIENT}>
+
+I<config/norelayclients>, I<config/relayclients>, I<config/morerelayclients> 
+
+The search order is as shown and cascades until a match is found or the list
+is exhausted. 
+
+Note that I<norelayclients> is the first file checked. A match there will
+override matches in the subsequent files.
+
+=head1 CONFIG
+
+Enable this plugin by adding it to config/plugins above the rcpt_* plugins
+
+ # other plugins...
+
+ relay
+
+ # rcpt_* go here
+
+=head2 relayclients
+
+A list of IP addresses that are permitted to relay mail through this server.
+
+Each line in I<relayclients> is one of:
+ - a full IP address
+
+ - partial IP address terminated by a dot or colon for matching whole networks
+     192.168.42.
+     fdda:b13d:e431:ae06:
+     ...
+
+ - a network/mask, aka a CIDR block
+     10.1.0.0/24
+     fdda:b13d:e431:ae06::/64
+     ...
+
+=head2 morerelayclients
+
+Additional IP addresses that are permitted to relay. The syntax of the config
+file is identical to I<relayclients> except that CIDR (net/mask) entries are
+not supported. If you have many (>50) IPs allowed to relay, most should likely
+be listed in I<morerelayclients> where lookups are faster.
+
+
+=head2 norelayclients
+
+I<norelayclients> allows specific clients, such as a mail gateway, to be denied
+relaying, even though they would be allowed by I<relayclients>. This is most
+useful when a block of IPs is allowed in relayclients, but several IPs need to
+be excluded.
+
+The file format is the same as morerelayclients.
+
+=head2 RELAY ONLY
+
+The relay only option restricts connections to only clients that have relay
+permission. All other connections are denied during the RCPT phase of the
+SMTP conversation.
+
+This option is useful when a server is used as the smart relay host for
+internal users and external/authenticated users, but should not be considered
+a normal inbound MX server.
+
+It should be configured to be run before other RCPT hooks! Only clients that
+have authenticated or are listed in the relayclient file will be allowed to
+send mail.
+
+To enable relay only mode, set the B<only> option to any true value in
+I<config/plugins> as shown:
+
+  relay only 1

+=head1 NAME
+
+karma - reward nice and penalize naughty mail senders
+
+=head1 SYNOPSIS
+
+Karma tracks sender history, providing the ability to deliver differing levels
+of service to naughty, nice, and unknown senders.
+
+=head1 DESCRIPTION
+
+Karma records the number of nice, naughty, and total connections from mail
+senders. After sending a naughty message, if a sender has more naughty than
+nice connections, they are penalized for I<penalty_days>. Connections
+from senders in the penalty box are tersely disconnected.
+
+Karma provides other plugins with a karma value they can use to be more
+lenient, strict, or skip processing entirely.
+
+Karma is small, fast, and ruthlessly efficient. Karma can be used to craft
+custom connection policies such as these two examples: 
+
+=over 4 
+
+Hi there, well behaved sender. Please help yourself to TLS, AUTH, greater
+concurrency, multiple recipients, no delays, and other privileges.
+
+Hi there, naughty sender. Enjoy this poke in the eye with a sharp stick. Bye.
+
+=back 
+
+=head1 CONFIG
+
+=head2 negative <integer>
+
+How negative a senders karma can get before we penalize them for sending a
+naughty message. Karma is the number of nice - naughty connections. 
+
+Default: 1
+
+Examples:
+
+ negative 1:  0 nice - 1 naughty = karma -1, penalize
+ negative 1:  1 nice - 1 naughty = karma  0, okay
+ negative 2:  1 nice - 2 naughty = karma -1, okay
+ negative 2:  1 nice - 3 naughty = karma -2, penalize
+
+With the default negative limit of one, there's a very small chance you could
+penalize a "mostly good" sender. Raising it to 2 reduces that possibility to
+improbable.
+
+=head2 penalty_days <days>
+
+The number of days a naughty sender is refused connections. Use a decimal
+value to penalize for portions of days.
+
+  karma penalty_days 1
+
+Default: 1
+
+=head2 reject
+
+  karma reject [ 0 | 1 | connect | zombie ]
+
+I<0> will not reject any connections.
+
+I<1> will reject naughty senders.
+
+I<connect> is the most efficient setting. 
+
+To reject at any other connection hook, use the I<zombie> setting and the
+B<reaper> plugin.
+
+=head2 db_dir <path>
+
+Path to a directory in which the DB will be stored. This directory must be
+writable by the qpsmtpd user. If unset, the first usable directory from the
+following list will be used:
+
+=over 4
+
+=item /var/lib/qpsmtpd/karma
+
+=item I<BINDIR>/var/db (where BINDIR is the location of the qpsmtpd binary)
+
+=item I<BINDIR>/config
+
+=back
+
+=head2 loglevel
+
+Adjust the quantity of logging for this plugin. See docs/logging.pod
+
+=head1 BENEFITS
+
+Karma reduces the resources wasted by naughty mailers. 
+When used with the 
+I<reject connect> setting, naughty senders are disconnected in about 0.1 seconds.
+
+The biggest gains to be had are by having heavy plugins (spamassassin, dspam,
+virus filters) set the B<karma> transaction note (see KARMA) when they encounter
+naughty senders. Reasons to send servers to the penalty box could include
+sending a virus, early talking, or sending messages with a very high spam
+score.
+
+This plugin does not penalize connections with transaction notes I<relayclient>
+or I<whitelisthost> set. These notes would have been set by the B<relay>, 
+B<whitelist>, and B<dns_whitelist_soft> plugins. Obviously, those plugins must
+run before B<karma> for that to work.
+
+=head1 KARMA
+
+No attempt is made by this plugin to determine what karma is. It is up to
+other plugins to make that determination and communicate it to this plugin by
+incrementing or decrementing the transaction note B<karma>. Raise it for good
+karma and lower it for bad karma. This is best done like so:
+
+ # only if karma plugin loaded
+ if ( defined $connection->notes('karma') ) {   
+   $connection->notes('karma', $connection->notes('karma') - 1); # bad
+   $connection->notes('karma', $connection->notes('karma') + 1); # good 
+ };
+
+After the connection ends, B<karma> will record the result. Mail servers whose
+naughty connections exceed nice ones are sent to the penalty box. Servers in
+the penalty box will be tersely disconnected for I<penalty_days>. Here is
+an example connection from an IP in the penalty box:
+
+ 73122 Connection from smtp.midsetmediacorp.com [64.185.226.65]
+ 73122 (connect) ident::geoip: US, United States
+ 73122 (connect) ident::p0f: Windows 7 or 8
+ 73122 (connect) earlytalker: pass: 64.185.226.65 said nothing spontaneous
+ 73122 (connect) relay: skip: no match
+ 73122 (connect) karma: fail
+ 73122 550 You were naughty. You are penalized for 0.99 more days.
+ 73122 click, disconnecting
+ 73122 (post-connection) connection_time: 1.048 s.
+
+If we only sets negative karma, we will almost certainly penalize servers we
+want to receive mail from. For example, a Yahoo user sends an egregious spam
+to a user on our server. Now nobody on our server can receive email from that
+Yahoo server for I<penalty_days>. This should happen approximately 0% of
+the time if we are careful to also set positive karma.
+
+=head1 USING KARMA
+
+To get rid of naughty connections as fast as possible, run karma before other
+connection plugins. Plugins that trigger DNS lookups or impose time delays
+should run after B<karma>. In this example, karma runs before all but the
+ident plugins.
+
+ 89011 Connection from Unknown [69.61.27.204]
+ 89011 (connect) ident::geoip: US, United States
+ 89011 (connect) ident::p0f: Linux 3.x
+ 89011 (connect) karma: fail, 1 naughty, 0 nice, 1 connects
+ 89011 550 You were naughty. You are penalized for 0.99 more days.
+ 89011 click, disconnecting
+ 89011 (post-connection) connection_time: 0.118 s.
+ 88798 cleaning up after 89011
+
+Unlike RBLs, B<karma> only penalizes IPs that have sent us spam, and only when
+those senders haven't sent us any ham. As such, it's much safer to use.
+
+=head1 USING KARMA IN OTHER PLUGINS
+
+This plugin sets the connection note I<karma_history>. Your plugin can
+use the senders karma to be more gracious or rude to senders. The value of
+I<karma_history> is the number the nice connections minus naughty
+ones. The higher the number, the better you should treat the sender.
+
+When I<reject zombie> is set and a naughty sender is encountered, most
+plugins should skip processing. However, if you wish to toy with spammers by
+teergrubing, extending banner delays, limiting connections, limiting
+recipients, random disconnects, handoffs to rblsmtpd, and other fun tricks, 
+then connections with the I<zombie> note set are for you!
+
+=head1 EFFECTIVENESS
+
+In the first 24 hours, B<karma> rejected 8% of all connections. After one
+week of running with I<penalty_days 1>, karma has rejected 15% of all
+connections.
+
+This plugins effectiveness results from the propensity of naughty senders
+to be repeat offenders. Limiting them to a single offense per day(s) greatly
+reduces the number of useless tokens miscreants add to our Bayes databases.
+
+Of the connections that had previously passed all other checks and were caught
+only by spamassassin and/or dspam, B<karma> rejected 31 percent. Since
+spamassassin and dspam consume more resources than others plugins, this plugin
+seems to be a very big win.
+
+=head1 DATABASE
+
+Connection summaries are stored in a database. The database key is the int
+form of the remote IP. The value is a : delimited list containing a penalty
+box start time (if the server is/was on timeout) and the count of naughty,
+nice, and total connections. The database can be listed and searched with the
+karma_dump.pl script.
+
+=head1 BUGS & LIMITATIONS
+
+This plugin is reactionary. Like the FBI, it doesn't punish until
+after a crime has been committed. It an "abuse me once, shame on you,
+abuse me twice, shame on me" policy.
+
+There is little to be gained by listing servers that are already on DNS
+blacklists, send to non-existent users, earlytalkers, etc. Those already have
+very lightweight tests.

+=head1 NAME
+
+helo - validate a HELO message delivered from a connecting host.
+
+=head1 DESCRIPTION
+
+This plugin validates the HELO hostname presented by a remote sender. It
+includes a suite of optional tests, selectable by the I<policy> setting.
+
+The following tests are available. The policy section details which tests
+are enforced by each policy:
+
+=over 4
+
+=item is_in_badhelo
+
+Matches in the I<badhelo> config file, including yahoo.com and aol.com, which
+neither the real Yahoo or the real AOL use, but which spammers use often.
+
+B<badhelo> can also contain perl regular expressions. In addition to normal
+regexp processing, a pattern can start with a ! character, and get a !~ match
+instead of the customary =~ match.
+
+=item invalid_localhost
+
+Assure that if a sender uses the 'localhost' hostname, they are coming from
+the localhost IP.
+
+=item is_plain_ip
+
+Disallow plain IP addresses. They are neither FQDN nor an address literal.
+
+=item is_address_literal [N.N.N.N]
+
+An address literal (an IP enclosed in brackets] is legal but rarely, if ever,
+encountered from legit senders. Disallow them.
+
+=item is_forged_literal
+
+If a literal is presented, make sure it matches the senders IP.
+
+=item is_not_fqdn 
+
+Makes sure the HELO hostname contains at least one dot and no invalid characters.
+
+=item no_forward_dns
+
+Make sure the HELO hostname resolves.
+
+=item no_reverse_dns
+
+Make sure the senders IP address resolves to a hostname.
+
+=item no_matching_dns
+
+Make sure the HELO hostname has an A or AAAA record that matches the senders
+IP address, and make sure that the senders IP has a PTR that resolves to the
+HELO hostname.
+
+This might sound pedantic, but since time immemorial, having matching DNS is
+a minimum standard expected, and frequently required, of mail servers.
+
+=back
+
+=head1 CONFIGURATION
+
+=head2 policy [ lenient | rfc | strict ]
+
+Default: lenient
+
+=head3 lenient
+
+Reject failures of the following tests: is_in_badhelo, invalid_localhost, and
+is_forged_literal.
+
+If you are not using the B<naughty> plugin, this setting is lenient enough
+not to cause problems for your Windows users. It also makes you more vulnerable
+to abuse by every other Windows PC connected to the internet.
+
+=head3 rfc
+
+Per RFC 2821, the HELO hostname must be the FQDN of the sending server or an
+address literal. When I<policy rfc> is selected, all the lenient checks and
+the following are enforced: is_plain_ip, is_not_fqdn, no_forward_dns,
+no_reverse_dns, and no_matching_dns.
+
+If you have Windows users that send mail via your server, do not choose RFC
+unless you are using the B<naughty> plugin. Windows users often send
+unqualified HELO names and will have trouble sending mail. <Naughty> can defer
+the rejection, and if the user authenticates, the reject is cancelled entirely.
+
+=head3 strict
+
+Strict includes all the RFC tests and also rejects adddress literals. So long
+as you use I<reject naughty>, this test should reject only spam.
+
+=head2 badhelo
+
+Add domains, hostnames, or perl regexp patterns to the F<badhelo> config
+file; one per line.
+
+=head2 reject [ 0 | 1 | naughty ]
+
+0: do not reject
+
+1: reject
+
+naughty: naughty plugin handles rejection
+
+Default: 1
+
+=head2 reject_type [ temp | perm | disconnect ]
+
+What type of rejection should be sent? See docs/config.pod
+
+=head2 loglevel
+
+Adjust the quantity of logging for this plugin. See docs/logging.pod
+
+=head1 RFC 2821
+
+=head2 4.1.1.1
+
+The HELO hostname "...contains the fully-qualified domain name of the SMTP
+client if one is available.  In situations in which the SMTP client system
+does not have a meaningful domain name (e.g., when its address is dynamically
+allocated and no reverse mapping record is available), the client SHOULD send
+an address literal (see section 4.1.3), optionally followed by information
+that will help to identify the client system."
+
+=head2 2.3.5
+
+The domain name, as described in this document and in [22], is the
+entire, fully-qualified name (often referred to as an "FQDN").  A domain name
+that is not in FQDN form is no more than a local alias.  Local aliases MUST
+NOT appear in any SMTP transaction.

+Using I<policy rfc> will reject a very large portion of the spam from hosts

+
+=head1 WHY IT WORKS
+
+The reverse DNS of the zombie PCs is out of the spam operators control. Their
+only way to get past these tests is to limit themselves to hosts with matching
+forward and reverse DNS, and then use the proper HELO hostname when spamming.
+At present, this presents a very high hurdle.

-This might sound pedantic, but since time immemorial, having matching DNS is
-a minimum standard expected, and frequently required, of mail servers.
+Since the dawn of SMTP, having matching DNS has been a minimum standard
+expected and oft required of mail servers. While requiring matching DNS is
+prudent, requiring an exact match will reject valid email. While testing this
+plugin with rejection disabled, I noticed that mx0.slc.paypal.com sends email
+from an IP that reverses to mx1.slc.paypal.com. While that's technically an
+error, I believe it's an error to reject mail based on it. Especially since
+SLD and TLD match.
+
+To avoid snagging false positives, matches are extended to the first
+3 octets of the IP and the last two labels of the FQDN. The following are
+considered a match:
+
+  192.0.1.2, 192.0.1.3
+
+  foo.example.com, bar.example.com
+
+This allows I<no_matching_dns> to be used without rejecting mail from orgs with
+pools of servers where the HELO name and IP don't exactly match. This list
+includes Yahoo, Gmail, PayPal, cheaptickets.com, exchange.microsoft.com, and
+likely many more.

-    The greylisting DB format has changed to accommodate IPv6 addresses. (The DB key has colon ':' seperated fields, and IPv6 addresses are colon delimited). The new format converts the IPs into integers. There is a new config option named 'upgrade' that when enabled, updates all the records in your DB to the new format. Simply add 'upgrade 1' to the plugin entry in config/plugins, start up qpsmtpd once, make one connection. A log entry will be made, telling how many records were upgraded. Remove the upgrade option from your config.
-
-SPF plugin:
-
-    spf_deny setting deprecated. Use reject N setting instead, which provides administrators with more granular control over SPF. For backward compatibility, a spf_deny setting of 1 is mapped to 'reject 3' and a 'spf_deny 2' is mapped to 'reject 4'.

+=head1 NAME
+
+headers
+
+=head1 DESCRIPTION
+
+Checks for missing or empty values in the From or Date headers.
+
+Make sure no singular headers are duplicated. Singular headers are:
+
+ Date From Sender Reply-To To Cc Bcc
+ Message-Id In-Reply-To References Subject
+
+Optionally test if the Date header is too many days in the past or future. If
+I<future> or I<past> are not defined, they are not tested.
+
+If the remote IP is whitelisted, header validation is skipped.
+
+=head1 CONFIGURATION
+
+The following optional settings exist:
+
+=head2 require
+
+ headers require [ From | Date | From,Date | From,Date,Subject,Message-ID ]
+
+A comma separated list of headers to require. 
+
+Default: From
+
+=head3 Requiring the Date header
+
+As of 2012, requiring a valid date header will almost certainly cause the loss
+of valid mail. The JavaMail sender used by some banks, photo processing
+services, health insurance companies, bounce senders, and others do send
+messages without a Date header. For this reason, and despite RFC 5322, the
+default is not to require Date.
+
+However, if the date header is present, and I<future> and/or I<past> are
+defined, it will be validated.
+
+=head2 future
+
+The number of days in the future beyond which messages are invalid.
+
+  headers [ future 1 ]
+
+=head2 past
+
+The number of days in the past beyond which a message is invalid. The Date header is added by the MUA, so there are many valid reasons a message may have an older date in the header. It could have been delayed by the client, the sending server, connectivity problems, recipient server problem, recipient server configuration, etc. The I<past> setting should take those factors into consideration.
+
+I would be surprised if a valid message ever had a date header older than a week.
+
+  headers [ past 5 ]
+
+=head2 reject
+
+Determine if the connection is denied. Use the I<reject 0> option when first enabling the plugin, and then watch your logs to see what would have been rejected. When you are no longer concerned that valid messages will be rejected, enable with I<reject 1>.
+
+  headers reject [ 0 | 1 ]
+
+Default: 1
+
+=head2 reject_type
+
+Whether to issue a permanent or temporary rejection. The default is permanent.
+
+  headers reject_type [ temp | perm ]
+
+Using a temporary rejection is a cautious way to enable rejections. It allows an administrator to watch for a trial period and assure no valid messages are rejected. If a deferral of valid mail is noticed, I<reject 0> can be set to permit the deferred message to be delivered.
+
+Default: perm
+
+=head2 loglevel
+
+Adjust the quantity of logging for this plugin. See docs/logging.pod

+=head1 NAME
+
+geoip - provide geographic information about mail senders.
+
 =head1 SYNOPSIS
 
-This plugin uses MaxMind's GeoIP service and the Geo::IP perl module to
-do a lookup on incoming connections and record the country of origin.
+Use MaxMind's GeoIP databases and the Geo::IP perl module to report geographic
+information about incoming connections.
 
-Thats all it does.
+=head1 DESCRIPTION
 
-It logs the 2 char country code to connection note I<geoip_country>.
-It logs the country name to the connection note I<geoip_country_name>.
+This plugin saves geographic information in the following connection notes:
 
-Other plugins can use that info to do things to the connection, like
-reject or greylist.
+  geoip_country      - 2 char country code
+  geoip_country_name - full english name of country
+  geoip_continent    - 2 char continent code
+  geoip_distance     - distance in kilometers
+
+And adds entries like this to your logs:
+
+  (connect) ident::geoip: US, United States, NA,    1319 km
+  (connect) ident::geoip: IN, India, AS,    13862 km
+  (connect) ident::geoip: fail: no results
+  (connect) ident::geoip: CA, Canada, NA,   2464 km
+  (connect) ident::geoip: US, United States, NA,    2318 km
+  (connect) ident::geoip: PK, Pakistan, AS,    12578 km
+  (connect) ident::geoip: TJ, Tajikistan, AS,  11965 km
+  (connect) ident::geoip: AT, Austria, EU,     8745 km
+  (connect) ident::geoip: IR, Iran, Islamic Republic of, AS,   12180 km
+  (connect) ident::geoip: BY, Belarus, EU,     9030 km
+  (connect) ident::geoip: CN, China, AS,   11254 km
+  (connect) ident::geoip: PA, Panama, NA,  3163 km
+
+Calculating the distance has three prerequsites:
+
+  1. The MaxMind city database (free or subscription)
+  2. The Math::Complex perl module
+  3. The IP address of this mail server (see CONFIG)
+
+Other plugins can utilize the geographic notes to alter the
+connection, reject, greylist, etc.
+
+=head1 CONFIG
+
+The following options can be appended in this plugins config/plugins entry.
+
+=head2 distance <IP Address>
+
+Enables geodesic distance calculation. Will calculate the distance "as the
+crow flies" from the remote mail server. Accepts a single argument, the IP
+address to calculate the distance from. This will typically be the public
+IP of your mail server.
+
+  ident/geoip [ distance 192.0.1.5 ]
+
+Default: none. (no distance calculations)
+
+=head2 db_dir </path/to/GeoIP>
+
+The path to the GeoIP database directory.
+
+  ident/geoip [ db_dir /etc/GeoIP ]
+
+Default: /usr/local/share/GeoIP
+
+=head1 LIMITATIONS
+
+The distance calculations are more concerned with being fast than accurate.
+The MaxMind location data is collected from whois and is of limited accuracy.
+MaxMind offers more accurate data for a fee.
+
+For distance calculations, the earth is considered a perfect sphere. In
+reality, it is not. Accuracy should be within 1%.
+
+This plugin does not update the GeoIP databases. You may want to.
+
+=head1 CHANGES
+
+2012-06 - Matt Simerson - added GeoIP City support, continent, distance
+
+2012-05 - Matt Simerson - added geoip_country_name note, added tests
+
+=head1 SEE ALSO
+
+MaxMind: http://www.maxmind.com/
+
+Databases: http://geolite.maxmind.com/download/geoip/database
+
+It may become worth adding support for Geo::IPfree, which uses another
+data source: http://software77.net/geo-ip/

+=head1 NAME
+
+naughty - dispose of naughty connections
+
+=head1 BACKGROUND
+
+Rather than immediately terminating naughty connections, plugins often mark
+the connections and dispose of them later. Examples are B<dnsbl>, B<karma>, 
+B<greylisting>, B<resolvable_fromhost> and B<SPF>. 
+
+This practice is based on RFC standards and the belief that malware will retry
+less if we disconnect after RCPT. This may have been true, and may still be,
+but my observations in 2012 suggest it makes no measurable difference whether
+I disconnect during connect or rcpt.
+
+Disconnecting later is inefficient because other plugins continue to do their
+work, oblivious to the fact that the connection is destined for the bit bucket.
+
+=head1 DESCRIPTION
+
+Naughty provides the following:
+
+=head2 efficiency
+
+Naughty provides plugins with an efficient way to offer late disconnects. It
+does this by allowing other plugins to detect that a connection is naughty.
+For efficiency, other plugins should skip processing naughty connections.
+Plugins like SpamAssassin and DSPAM can benefit from using naughty connections
+to train their filters.
+
+Since so many connections are from blacklisted IPs, naughty significantly
+reduces the processing time required for disposing of them. Over 80% of my
+connections are disposed of after after a few DNS queries (B<dnsbl> or one DB
+query (B<karma>) and 0.01s of compute time.
+
+=head2 naughty cleanup
+
+Instead of each plugin handling cleanup, B<naughty> does it. Set I<reject> to
+the hook you prefer to reject in and B<naughty> will reject the naughty
+connections, regardless of who identified them, exactly when you choose.
+
+=head2 simplicity
+
+Rather than having plugins split processing across hooks, they can run to
+completion when they have the information they need, issue a 
+I<reject naughty> if warranted, and be done.
+
+This may help reduce the code divergence between the sync and async
+deployment models.
+
+=head2 authentication
+
+When a user authenticates, the naughty flag on their connection is cleared.
+This is to allow users to send email from IPs that fail connection tests such
+as B<dnsbl>. Keep in mind that if I<reject connect> is set, connections will
+not get the chance to authenticate.
+
+=head2 naughty
+
+<naughty> provides a a consistent way for plugins to mark connections as
+naughty. Set the connection note I<naughty> to the message you wish to send
+the naughty sender during rejection.
+
+   $self->connection->notes('naughty', $message);
+
+This happens for plugins automatically if they use the $self->get_reject()
+method and have set I<reject naughty> in the plugin configuration.
+

+
+=head2 reject

+  naughty reject [ connect | mail | rcpt | data | data_post ]
+
+The phase of the connection in which the naughty connection will be terminated.
+Keep in mind that if you choose rcpt and a plugin (like B<rcpt_ok>) runs first,
+and B<rcpt_ok> returns OK, then this plugin will not get called and the
+message will not get rejected.
+
+Solutions are to make sure B<naughty> is listed before rcpt_ok in config/plugins
+or set naughty to run in a phase after the one you wish to complete.
+In this case, use data instead of rcpt to disconnect after rcpt_ok. The latter
+is particularly useful if your rcpt plugins skip naughty testing. In that case,
+any recipient is accepted for naughty connections, which prevents spammers
+from detecting address validity.

-=head1 SYNOPSIS
-
-This plugin checks the badrcptto_patterns config. This allows
-special patterns to be denied (e.g. percent hack, bangs, 
-double ats).
-
-=head1 CONFIG
-
-config/badrcptto_patterns
-
-Patterns are stored in the format pattern\sresponse, where pattern
-is a Perl pattern expression. Don't forget to anchor the pattern if
-you want to restrict it from matching anywhere in the string.
-
-qpsmtpd already ensures that the address contains an @, with something
-to the left and right of the @.

Subject: [PATCH 1175/1467] Plugin.pm: more descriptive variable names

append optional log_mess to log entry (more description)

set the naughty rejection type to be the reject type of the plugin that marked the connection naughty
get_reject_type can be passed an explicit default

-=head1 NAME
-
-check_basicheaders
-
-=head1 DESCRIPTION
-
-Checks for missing or empty values in the From or Date headers.
-
-Optionally test if the Date header is too many days in the past or future. If
-I<future> or I<past> are not defined, they are not tested.
-
-If the remote IP is whitelisted, header validation is skipped.
-
-=head1 CONFIGURATION
-
-The following optional settings exist:
-
-=head2 future
-
-The number of days in the future beyond which messages are invalid.
-
-  check_basicheaders [ future 1 ]
-
-=head2 past
-
-The number of days in the past beyond which a message is invalid. The Date header is added by the MUA, so there are many valid reasons a message may have an older date in the header. It could have been delayed by the client, the sending server, connectivity problems, recipient server problem, recipient server configuration, etc. The I<past> setting should take those factors into consideration.
-
-I would be surprised if a valid message ever had a date header older than a week.
-
-  check_basicheaders [ past 5 ]
-
-=head2 reject
-
-Determine if the connection is denied. Use the I<reject 0> option when first enabling the plugin, and then watch your logs to see what would have been rejected. When you are no longer concerned that valid messages will be rejected, enable with I<reject 1>.
-
-  check_basicheaders reject [ 0 | 1 ]
-
-Default: 1
-
-=head2 reject_type
-
-Whether to issue a permanent or temporary rejection. The default is permanent.
-
-  check_basicheaders reject_type [ temp | perm ]
-
-Using a temporary rejection is a cautious way to enable rejections. It allows an administrator to watch for a trial period and assure no valid messages are rejected. If a deferral of valid mail is noticed, I<reject 0> can be set to permit the deferred message to be delivered.
-
-Default: perm
-
-=head2 loglevel
-
-Adjust the quantity of logging for this plugin. See docs/logging.pod
-
-=head1 AUTHOR
-
- 2004 - Written by Jim Winstead Jr.

-      - deprecate days for I<past> & I<future>. Improved POD

 =head1 MOTIVATION
 
 This p0f plugin provides a way to make sophisticated policies for email
 messages. For example, the vast majority of email connections to my server
-from Windows computers are spam (>99%). But, I have a few clients that use
-Exchange servers so I can't just block email from all Windows computers.

-instant or never. When I enable greylisting, I lose valid messages. Grrr.

Subject: [PATCH 1227/1467] dspam: fixes for training dspam

process_backticks now writes the entire message (headers + body) to a temp file and had dspam read that. Previously, dspam only read the body.  With the new "process, then train on error" method, dspam didn't have access to the DSPAM signature (in the headers).

replaced open2 with open3. Same results. Works part of the time, but not consistent, and I haven't been able to figure out why.

dspam transaction note is now a hashref (was a string)
parsing of dspam response via substring (was regexp)

+=head1 NAME
+
+qmail_deliverable - Check that the recipient address is deliverable
+
+=head1 DESCRIPTION
+
+See the description of Qmail::Deliverable.
+
+This B<qpsmtpd plugin> uses the client/server interface and needs a running
+qmail-deliverabled. If no connection can be made, deliverability is simply
+assumed.
+
+The modules LWP (libwww-perl) and HTTP::Daemon, available from CPAN, are
+required for qmail-deliverabled and Qmail::Deliverable::Client.
+
+=head1 CONFIGURATION
+
+=over 4
+
+=item server host:port
+
+Hostname (or IP address), and port (both!) of the qmail-deliverabled server. If
+none is specified, the default (127.0.0.1:8998) is used.
+
+=item server smtproutes:host:port
+
+If the specification is prepended by the literal text C<smtproutes:>, then for
+recipient domains listed in your /var/qmail/control/smtproutes use their
+respective hosts for the check. For other domains, the given host is used. The
+port has to be the same across all servers.
+
+Example:
+
+    qmail_deliverable server smtproutes:127.0.0.1:8998
+
+Use "smtproutes:8998" (no second colon) to simply skip the deliverability
+check for domains not listed in smtproutes.
+
+=back
+
+=head1 CAVEATS
+
+Given a null host in smtproutes, the normal MX lookup should be used. This
+plugin does not do this, because we don't want to harrass arbitrary servers.
+
+Connection failure is *faked* when there is no smtproute.
+

+warranty or guarantee of any kind. Use it at your own risk.

+
+I first attempted to fix the dkimcheck plugin, but soon scrapped that effort and wrote this one.
+
+The nine 'if' brackets with 19 conditionals, and my inability to easily determine which of the 15 possible permutations (5 signature validation results x 3 possible policy results) were covered.
+
+The use of $dkim->fetch_author_policy, which is deprecated by Mail::DKIM.
+
+The paradim of a single policy, when DKIM supports 0 or many. Although I may yet implement the 'local' policy idea, so long as I'm confident it will never result in a false positive.
+
+The OBF programming style, which is nigh impossible to test.

+=head1 NAME
+
+whitelist - whitelist override for other qpsmtpd plugins
+
+
+=head1 DESCRIPTION
+
+The B<whitelist> plugin allows selected hosts or senders or recipients 
+to be whitelisted as exceptions to later plugin processing. It is a more
+conservative variant of Devin Carraway's 'whitelist' plugin.
+
+
+=head1 CONFIGURATION
+
+To enable the plugin, add it to the qpsmtpd/config/plugins file as usual.
+It should precede any plugins you might wish to whitelist for.
+
+Several configuration files are supported, corresponding to different
+parts of the SMTP conversation:
+
+=over 4
+
+=item whitelisthosts
+
+Any IP address (or start-anchored fragment thereof) listed in the
+whitelisthosts file is exempted from any further validation during 
+'connect', and can be selectively exempted at other stages by 
+plugins testing for a 'whitelisthost' connection note.
+
+Similarly, if the environment variable $WHITELISTCLIENT is set
+(which can be done by tcpserver), the connection will be exempt from
+further 'connect' validation, and the host can be selectively 
+exempted by other plugins testing for a 'whitelistclient' connection 
+note.
+
+=item whitelisthelo
+
+Any host that issues a HELO matching an entry in whitelisthelo will
+be exempted from further validation at the 'helo' stage. Subsequent
+plugins can test for a 'whitelisthelo' connection note. Note that 
+this does not actually amount to an authentication in any meaningful 
+sense.
+
+=item whitelistsenders
+
+If the envelope sender of a mail (that which is sent as the MAIL FROM)
+matches an entry in whitelistsenders, or if the hostname component 
+matches, the mail will be exempted from any further validation within
+the 'mail' stage. Subsequent plugins can test for this exemption as a 
+'whitelistsender' transaction note.
+
+=item whitelistrcpt
+
+If any recipient of a mail (that sent as the RCPT TO) matches an
+entry from whitelistrcpt, or if the hostname component matches, no 
+further validation will be required for this recipient. Subsequent 
+plugins can test for this exemption using a 'whitelistrcpt' 
+transaction note, which holds the count of whitelisted recipients.
+
+=back
+
+whitelist_soft also supports per-recipient whitelisting when using
+the per_user_config plugin. To enable the per-recipient behaviour 
+(delaying all whitelisting until the rcpt part of the smtp 
+conversation, and using per-recipient whitelist configs, if 
+available), pass a true 'per_recipient' argument in the
+config/plugins invocation i.e.
+
+  whitelist_soft per_recipient 1
+
+By default global and per-recipient whitelists are merged; to turn off
+the merge behaviour pass a false 'merge' argument in the config/plugins
+invocation i.e.
+
+  whitelist_soft per_recipient 1 merge 0
+
+
+=head1 BUGS
+
+Whitelist lookups are all O(n) linear scans of configuration files, even
+though they're all associative lookups.  Something should be done about
+this when CDB/DB/GDBM configs are supported.
+
+
+=head1 AUTHOR
+
+Based on the 'whitelist' plugin by Devin Carraway <qpsmtpd@devin.com>.
+
+Modified by Gavin Carr <gavin@openfusion.com.au> to not inherit 
+whitelisting across hooks, but use per-hook whitelist notes instead.
+This is a more conservative approach e.g. whitelisting an IP will not
+automatically allow relaying from that IP.

+
+Forward Confirmed RDNS - http://en.wikipedia.org/wiki/FCrDNS
+
+=head1 DESCRIPTION
+
+Determine if the SMTP sender has matching forward and reverse DNS. 
+
+Sets the connection note fcrdns.
+
+=head1 WHY IT WORKS
+
+The reverse DNS of zombie PCs is out of the spam operators control. Their
+only way to pass this test is to limit themselves to hosts with matching
+forward and reverse DNS. At present, this presents a significant hurdle.
+
+=head1 VALIDATION TESTS
+
+=over 4
+
+=item has_reverse_dns
+
+Determine if the senders IP address resolves to a hostname.
+
+=item has_forward_dns
+
+If the remote IP has a PTR hostname(s), see if that host has an A or AAAA. If
+so, see if any of the host IPs (A or AAAA records) match the remote IP.
+
+Since the dawn of SMTP, having matching DNS has been a standard expected and
+oft required of mail servers. While requiring matching DNS is prudent,
+requiring an exact match will reject valid email. This often hinders the
+use of FcRDNS. While testing this plugin, I noticed that mx0.slc.paypal.com
+sends mail from an IP that reverses to mx1.slc.paypal.com. While that's
+technically an error, so too would rejecting that connection.
+
+To avoid false positives, matches are extended to the first 3 octets of the
+IP and the last two labels of the FQDN. The following are considered a match:
+
+  192.0.1.2, 192.0.1.3
+
+  foo.example.com, bar.example.com

+=head1 RFC 1912, RFC 5451
+
+From Wikipedia summary:
+
+1. First a reverse DNS lookup (PTR query) is performed on the IP address, which returns a list of zero or more PTR records. (has_reverse_dns)
+
+2. For each domain name returned in the PTR query results, a regular 'forward' DNS lookup (type A or AAAA query) is then performed on that domain name. (has_forward_dns)
+
+3. Any A or AAAA record returned by the second query is then compared against the original IP address (check_ip_match), and if there is a match, then the FCrDNS check passes.

-=head1 FAQ
-
-=head2 Q: Do I need to enable a logging plugin?
-
-=head2 A: No.
-
-When zero logging plugins are configured, logs are directed to STDERR. This
-is the 'default' logging and logs are piped to multilog and stored in
-log/main/current.
-
-When more than zero logging plugins are enabled, builtin logging is disabled
-and logs are sent to every logging plugin configured in config/plugins.
-
-
-=head2 Q: How do I watch the logs?
-
-=head2 A: Here's a few examples:
-
-The default log files can be watched in real time lik this:
-
- tail -F ~smtpd/log/main/current
-
-To convert the tai timestamps to human readable date time:
-
- tail -F ~smtpd/log/main/current | tai64nlocal
-
-To exclude the dates entirely, use this command:
-
- tail -F ~smtpd/smtpd/log/main/current | cut -d' ' -f2-3
-
-
-=head2 Q: How do I get alerts when qpsmtpd has a problem?
-
-=head2 A: Send logs with levels below LOGERROR to syslog.
-
-This can be done by adding the following lines to config/plugins:
-
-  logging/syslog loglevel LOGERROR
-  logging/warn LOGINFO
-
-The warn logging plugin replicates the builtin logging, directing log messages to STDERR. The syslog plugin directs errors to syslog where standard monitoring tools can pick them up and act on them.
-
-With these settings, errors will still get sent to STDERR as well.

+=head1 HOW TO SIGN
+
+=head2 generate DKIM key(s)
+
+  mkdir -p ~smtpd/config/dkim/example.org
+  cd       ~smtpd/config/dkim/example.org
+  echo 'mar2013' > selector
+  openssl genrsa -out private 2048
+  chmod 400 private
+  openssl rsa -in private -out public -pubout
+  chown -R smtpd:smtpd ~smtpd/config/dkim/example.org
+
+After running the commands, you'll have a directory with three files:
+
+  example.org
+  example.org/selector
+  example.org/private
+  example.org/public
+
+=head3 selector
+
+The selector can be any value that is a valid DNS label.
+
+=head3 key length
+
+The minimum recommended key length for short duration keys (ones that will be replaced within a few months) is 1024. If you are unlikely to rotate your keys frequently, go with 2048, at the expense of more CPU.
+
+=head2 publish public key in DNS
+
+  mar2013._domainkey TXT "v=DKIM1;p=[public key stripped of whitespace];"
+
+  hash: h=[ sha1 | sha256 ]
+  test; t=[ s | s:y ]
+  granularity: g=[ ]
+  notes: n=[ ]
+  services: s=[email]
+  keytypes: [ rsa ]
+
+Prepare the DNS record with these commands:
+
+  cd ~smtpd/config/dkim/example.org
+  cat selector | tr -d "\n" > dns
+  echo -n '._domainkey TXT "v=DKIM1;p=' >> dns
+  grep -v -e '^-' public | tr -d "\n" >> dns
+  echo '"' >> dns
+
+The contents of I<dns> are ready to be copy/pasted into a BIND zone file, or better yet, NicTool, and published to most any DNS server.
+
+=head2 testing
+
+After confirming that the DKIM public key can be fetched with DNS, send test messages via QP to a Gmail box and check the Authentication-Results header. There are also DKIM relays (check-auth@verifier.port25.com, checkmyauth@auth.returnpath.net) that provide more debugging information in a nice email report.
+
+=head2 Sign for others
+
+Following the directions above will configure QP to DKIM sign messages from authenticated senders from example.org. Suppose you host client.com and would like to DKIM sign their messages too? Do that as follows:
+
+  cd ~smtpd/config/dkim/example.org
+  ln -s example.org client.com
+
+QP will follow the symlink target and sign client.com emails with the example.org DKIM key.

+  r=[email] - responsible email address
+  n=[notes]
+
+Once DKIM and SPF are tested and working, update the policy, changing o=~ to o=-, so that other mail servers reject unsigned messages claiming to be from your domain.
+
+As of this writing, most mail servers do not reject messages that fail DKIM policy, unless they also fail SPF, and no DMARC policy is published. The same holds true for SPF. There are technical reasons for this. See DMARC for more information, how you can control change that behavior, as well as receiving feedback from remote servers about messages they have accepted and rejected from senders claiming the identity of your domain(s).

 As of this writing, most mail servers do not reject messages that fail DKIM policy, unless they also fail SPF, and no DMARC policy is published. The same holds true for SPF. There are technical reasons for this. See DMARC for more information, how you can control change that behavior, as well as receiving feedback from remote servers about messages they have accepted and rejected from senders claiming the identity of your domain(s).

 Sender Policy Framework (SPF) is an email validation system designed to prevent source address spoofing. SPF allows administrators to specify which hosts are allowed to send email from a given domain by creating a specific SPF record in the public DNS. Mail exchangers then use the DNS to verify that mail is being sent by a host sanctioned by a given domain administrators. -- http://en.wikipedia.org/wiki/Sender_Policy_Framework

+=head1 NAME
+
+Domain-based Message Authentication, Reporting and Conformance
+
+=head1 SYNOPSIS
+
+From the DMARC Draft: "DMARC operates as a policy layer atop DKIM and SPF. These technologies are the building blocks of DMARC as each is widely deployed, supported by mature tools, and is readily available to both senders and receivers. They are complementary, as each is resilient to many of the failure modes of the other."
+
+DMARC provides a way to exchange authentication information and policies among mail servers.
+
+DMARC benefits domain owners by preventing others from impersonating them. A domain owner can reliably tell other mail servers that "it it doesn't originate from this list of servers (SPF) and it is not signed (DKIM), then reject it!" DMARC also provides domain owners with a means to receive feedback and determine that their policies are working as desired.
+
+DMARC benefits mail server operators by providing them with an extremely reliable (as opposed to DKIM or SPF, which both have reliability issues when used independently) means to block forged emails. Is that message really from PayPal, Chase, Gmail, or Facebook? Since those organizations, and many more, publish DMARC policies, operators have a definitive means to know.
+
+=head1 HOW IT WORKS
+
+=head1 HOWTO
+
+See Section 10 of the draft: Domain Owner Actions
+
+1. Deploy DKIM & SPF
+2. Ensure identifier alignment.
+3. Publish a "monitor" record, ask for data reports
+4. Roll policies from monitor to reject
+
+=head2 Publish a DMARC policy
+
+ v=DMARC1;    (version)
+ p=none;      (disposition policy : reject, quarantine, none (monitor))
+ sp=reject;   (subdomain policy: default, same as p)
+ rua
+ adkim=s;     (dkim alignment: s=strict, r=relaxed)
+ aspf=r;      (spf  alignment: s=strict, r=relaxed)
+ rua=mailto: dmarc-feedback\@$zone;  (aggregate reports)
+ ruf=mailto: dmarc-feedback\@$zone.com; (forensic reports)
+ rf=afrf;     (report format: afrf, iodef)
+ ri=8400;     (report interval)
+ pct=50;      (percent of messages to filter)
+ 
+
+=head2 
+
+=head1 DRAFT
+
+http://www.dmarc.org/draft-dmarc-base-00-02.txt
+
+=head1 TODO
+
+ 1. run dmarc before SPF, if DMARC policy is discovered, ignore SPF
+
+ 2. provide dmarc feedback to domains that request it
+
+ 3. If a message has multiple 'From' recipients, reject it
+
+ 4. Rejections with a 550 (perm) or 450 (temp)
+
+=head1 IMPLEMENTATION
+
+1. Primary identifier is RFC5322.From field
+
+2. Senders can specify strict or relaxed mode
+
+3. policies available: reject, quarantine, no action
+
+4. DMARC overrides other public auth mechanisms
+
+5. senders can specify a percentage of messages to which policy applies
+
+6. Receivers should endeavour to reject or quarantine email if the
+   RFC5322.From purports to be from a domain that appears to be
+   either non-existent or incapable of receiving mail.
+
+=head2 Reports should include
+
+The report SHOULD include the following data:
+
+   o  Enough information for the report consumer to re-calculate DMARC
+      disposition based on the published policy, message dispositon, and
+      SPF, DKIM, and identifier alignment results. {R12}
+
+   o  Data for each sender subdomain separately from mail from the
+      sender's organizational domain, even if no subdomain policy is
+      applied. {R13}
+
+   o  Sending and receiving domains {R17}
+
+   o  The policy requested by the Domain Owner and the policy actually
+      applied (if different) {R18}
+
+   o  The number of successful authentications {R19}
+
+   o  The counts of messages based on all messages received even if
+      their delivery is ultimately blocked by other filtering agents
+      {R20}

 naughty - dispose of naughty connections
 
+=head1 SYNOPSIS
+
+Rather than immediately terminating naughty connections, plugins can flag the connection and dispose of it later. Examples are B<dnsbl>, B<karma>, B<greylisting>, B<resolvable_fromhost>, B<SPF>, and B<DKIM>.
+
 =head1 BACKGROUND
 
-Rather than immediately terminating naughty connections, plugins often mark
-the connections and dispose of them later. Examples are B<dnsbl>, B<karma>,
-B<greylisting>, B<resolvable_fromhost> and B<SPF>.
+Historically, deferred rejection was based on the belief that malware will retry less if we disconnect after RCPT. Observations in 2012 suggest it makes no measurable difference when we disconnect.
 
-This practice is based on RFC standards and the belief that malware will retry
-less if we disconnect after RCPT. This may have been true, and may still be,
-but my observations in 2012 suggest it makes no measurable difference whether
-I disconnect during connect or rcpt.
+Disconnecting early will block connections from your users who are roaming, or whose IP space is voluntarily listed by their ISP. Deferring rejection until after the remote has had the ability to authenticate allows RBLs to be safely used on port 25 and 587.
 
-Disconnecting later is inefficient because other plugins continue to do their
-work, oblivious to the fact that a connection is destined for the bit bucket.
+Some (much older) RFCs suggest deferring later.
+
+For these and other reasons, a few plugins implemented deferred rejection on their own. By having naughty, other plugins can be much simpler.
 
 =head1 DESCRIPTION
 
 Naughty provides the following:
 
+=head2 consistency
+
+With one change to the config of naughty, all plugins can reject their messages at the preferred time. I use this feature for spam filter training. When setting up a new server, I use 'naughty reject data_post' until after dspam is trained. Once the bayesian filters are trained, I change to 'naughty reject data', and avoid processing the message bodies.
+
 =head2 efficiency
 
-Naughty provides plugins with an efficient way to offer late disconnects. It
-does this by allowing other plugins to detect that a connection is naughty.
-For efficiency, other plugins should skip processing naughty connections.
-Plugins like SpamAssassin and DSPAM can benefit from using naughty connections
-to train their filters.
+After a connection is marked as naughty, subsequent plugins can detect that and skip processing. Plugins like SpamAssassin and DSPAM can benefit from using naughty connections to train their filters.
 
-Since many connections are from blacklisted IPs, naughty significantly
-reduces the resources required to dispose of them. Over 80% of my
-connections are disposed of after after a few DNS queries (B<dnsbl> or one DB
-query (B<karma>) and 0.01s of compute time.
-
-=head2 naughty cleanup
-
-Instead of each plugin handling cleanup, B<naughty> does it. Set I<reject> to
-the hook you prefer to reject in and B<naughty> will reject the naughty
-connections, regardless of who identified them, exactly when you choose.
-
-For training spam filters, I<reject data_post> is best.
+Since many connections are from blacklisted IPs, naughty significantly reduces the resources required to dispose of them. Over 80% of my connections are disposed of after after a few DNS queries (B<dnsbl> or one DB query (B<karma>) and 0.01s of compute time.
 
 =head2 simplicity
 
-Rather than having plugins split processing across hooks, they can run to
-completion when they have the information they need, issue a
-I<reject naughty> if warranted, and be done.

 =head2 authentication
 
-When a user authenticates, the naughty flag on their connection is cleared.
-This is to allow users to send email from IPs that fail connection tests such
-as B<dnsbl>. Note that if I<reject connect> is set, connections will
-not get the chance to authenticate. To allow clients a chance to authenticate,
-I<reject mail> works well.

+Qpsmtpd-dev is a fork of Qpsmtpd. Qpsmtpd is a very good SMTP daemon for
+developers and hackers (admittedly, its focus). It is difficult to install
+and administer for the typical sysadmin/user.
+
+The primary focus of the -dev branch is improving the consistency and
+behavior of the plugins. After using one plugin, the knowledge gained
+should carry over to other plugins.
+
+Secondary goals are reducing code duplication and complexity. Anything
+covered in Perl Best Practices is also fair game.
+
+So far, the main changes between the release and dev branches have focused

 Qpsmtpd-dev is a fork of Qpsmtpd. Qpsmtpd is a very good SMTP daemon for

+developers and hackers (admittedly, its focus). The plugin system is great
+but the plugin organization, documentation, and consistency left much
+to be desired.
 
 The primary focus of the -dev branch is improving the consistency and
 behavior of the plugins. After using one plugin, the knowledge gained
 should carry over to other plugins.
 
-Secondary goals are reducing code duplication and complexity. Anything

+Secondary goals are making it easier to install, reducing code duplication,
+reducing complexity, and cooperation between plugins. Anything covered
+in Perl Best Practices is also fair game.
 
 So far, the main changes between the release and dev branches have focused
 on these goals:
 
-  - plugins emit a single entry summarizing their disposition
+  - plugins log a single entry summarizing their disposition
   - plugin logs prefixed with keywords: pass, fail, skip, error
-  - plugins use 'reject' and 'reject_type' settings.
+  - plugins use 'reject' and 'reject_type' settings
   - plugins support deferred rejection via 'naughty' plugin
   - plugins get a resolver via $self->init_resolver
+  - new plugins: fcrdns, dmarc, naughty, karma
 
+An example of plugin cooperation is karma. Karma is a scorekeeper that aggregates bits of information from many plugins. Those bits alone are insufficient for acting on.  Examples of such data are:
+
+  FcRDNS - whether or not hostname has Forward confirmed reverse DNS
+  GeoIP distance - how many km away the sender is
+  p0f    - senders Operating System
+  helo   - helo hostname validity
+
+For most sites, even DNSBL, SPF, DKIM, and SpamAssassin tests alone are insufficient rejection criteria. But when these bits are combined, they can create an extremely reliable means to block spam.

+DMARC is an extremely reliable means to authenticate email.

+=head1 DESCRIPTION

 From the DMARC Draft: "DMARC operates as a policy layer atop DKIM and SPF. These technologies are the building blocks of DMARC as each is widely deployed, supported by mature tools, and is readily available to both senders and receivers. They are complementary, as each is resilient to many of the failure modes of the other."
 
 DMARC provides a way to exchange authentication information and policies among mail servers.

 DMARC benefits mail server operators by providing them with an extremely reliable (as opposed to DKIM or SPF, which both have reliability issues when used independently) means to block forged emails. Is that message really from PayPal, Chase, Gmail, or Facebook? Since those organizations, and many more, publish DMARC policies, operators have a definitive means to know.

+The display autosizes to display disposition results for as many plugins as are emitting logs. The 3 char abbreviations are listed with their full plugin names in plugins/registry.txt. The GeoIP, p0f, HELO, FROM, and RCPT fields are compressed to fit on a typical display. If you have a wider display, use the -l option to display longer lines and more detail.
+
+Starting from left to right, in the first block, the results are interpreted as follows:
+
+ geo - We see 2 connections from N. America, 3 from S. America, and 3 from Europe.
+ p0f - One system is running FreeBSD and the rest are running Windows 7.
+ krm - 3 of the connections will be rejected because of bad karma (sender history)
+ dbl - 7 are from IPs on DNS blacklists, an offense worth rejecting for.
+ rly - None of the IPs have relay permission.
+ dns - Only three senders have Forward Confirmed Reverse DNS
+ ear - two connections skipped testing (good karma), and the rest passed
+ hlo - three of the senders failed to present valid HELO hostnames
+ tls - one sender negotiated TLS
+ bmf - none of the senders presented a from address in our badmailfrom list
+ rbl - none of the sender domains are in a RHS blocking list
+ rfh - resolvable_from_host: all the sender domains resolve
+ spf - all but two connections fail SPF, meaning they are forging the envelope sender identity
+ bto - badmailto: none of the recipients are in our badmailto list
+ qmd - qmail_deliverable: the recipients are valid addresses on our system
+ rok - the recipient domain is on our system
+ tim - the number of seconds the connection was active
+
+In the second block, we have two messages that were ultimately delivered.
+
+ bog - no messages were bogus bounces
+ hdr - the messages had valid headers
+ dky - the messages were not DomainKeys signed
+ dkm - two messages were DKIM signed and passed validation
+ dmc - the message from amazon.com passed DMARC validation
+ spm - spamassassin, one skipped processing, one passed
+ dsp - dspam, one skipped, one passed
+ clm - clamav, one skipped, one passed
+ qqm - qmail queue, two messages were delivered
+
+In the first block of entries, not a single connection made it past the DATA phase of the SMTP conversation, where the content tests kick in. Other interesting observations are that many connections purport to be from Google. Ah, you say, but does Google have Windows mail servers in Estonia? If we look over to the SPF column, the lower case x is telling us that it failed SPF tests, meaning Google has explicitely told us that IP is not theirs. Instead of rejecting immediately, the SPF plugin deferred the rejection to B<naughty> to disconnect later.

Subject: [PATCH 1456/1467] raised default max msg size in clamdscan from 128k

added max_size on config, so it's likely to get noticed, since even 1M is probably too low for most sites. This should likely default to the same as databytes?

Subject: [PATCH 1463/1467] tested and working Authentication-Results

changed the method of saving results. Instead of appending to/from a header, plugins save results to a connection note.

Qpsmtpd::SMTP.pm has a new method that inserts the Authentication-Results header
The smtp-auth information has been removed from the Received header

Authentication-Results providing plugins have been updated to store results in connection note

-When upgrading from:
-
-v 0.84 or below
-
-CHECK_RELAY, CHECK_NORELAY, RELAY_ONLY
-
-    All 3 plugins are deprecated and replaced with a new 'relay' plugin. The new plugin reads the same config files (see 'perldoc plugins/relay') as the previous plugins. To get the equivalent functionality of enabling 'relay_only', use the 'only' argument to the relay plugin as documented in the RELAY ONLY section of plugins/relay.
-
-GREYLISTING plugin:
-
-    'mode' config argument is deprecated. Use reject and reject_type instead.
-
-    The greylisting DB format has changed to accommodate IPv6 addresses. (The DB key has colon ':' seperated fields, and IPv6 addresses are colon delimited). The new format converts the IPs into integers. There is a new config option named 'upgrade' that when enabled, updates all the records in your DB to the new format. Simply add 'upgrade 1' to the plugin entry in config/plugins, start up qpsmtpd once, make one connection. A log entry will be made, telling how many records were upgraded. Remove the upgrade option from your config.
-
-SPF plugin:
-
-    spf_deny setting deprecated. Use reject N setting instead, which provides administrators with more granular control over SPF. For backward compatibility, a spf_deny setting of 1 is mapped to 'reject 3' and a 'spf_deny 2' is mapped to 'reject 4'.
-
-
-P0F plugin:
-    defaults to p0f v3 (was v2).
-
-    Upgrade p0f to version 3 or add 'version 2' to your p0f line in config/plugins. perldoc plugins/ident/p0f for more details.
