STARTTLS support (see plugins/tls)
Added queue/exim-bsmtp plugin to spool accepted mail into an Exim
backend via BSMTP. (Devin Carraway)
New plugin inheritance system, see the bottom of README.plugins for
more information

(also: no more signal problems making qpsmtpd-forkserver crash/loop
when forking).
qpsmtpd-forkserver: add an option for writing a PID file (pjh)

postfix backend, which expects to have write permission to a fifo
which usually belongs to group postdrop). (pjh)
qpsmtpd-forkserver: if -d or --detach is given on the commandline,

an explicit $QPSMTPD_CONFIG variable to specify where the config lives,
overriding $QMAIL/control and /var/qmail/control if set. The usual

If the environment variable $QPSMTPD_CONFIG is set, qpsmtpd will look
for its config files in the directory given therein, in addition to (and
in preference to) other locations. (Peter J. Holzer)
Updated documentation
Various minor cleanups
0.30 - 2005/07/05

LDAP database. Thanks to Elliot Foster <elliotf@gratuitous.net>
new plugin: plugins/auth/auth_flat_file - flat file auth plugin
new plugin: plugins/auth/auth_cvm_unix_local - Only DENY if the
credentials were accepted but incorrect (bad password?). Interfaces
with Bruce Guenther's Credential Validation Module (CVM)
Revamp Qpsmtpd::Constants so it is possible to retrieve the text
representation from the numeric (for logging purposes).
new plugin: plugins/check_badrcptto_patterns - Match bad RCPTO
address with regex (Gordon Rowell)
new plugin: plugins/check_norelay - Carve out holes from larger
relay blocks (Also Gordon Rowell)
new plugin: plugins/virus/sophie - Uses SOPHOS Antivirus via Sophie

the complete message) and ignore old headers before adding lines and
queuing for delivery.
New anti-virus scanners: hbedv (Hanno Hecker), bitdefender, and clamdscan
(John Peacock). Update clamav plugin to directly scan the spool file.
New temp_file() and temp_dir() methods; when used by plugins, they create
a filename or directory which will last only as long as the current
transaction. Also created a spool_dir() method which checks/creates the
spool_dir when the application starts up. All three methods are also
available in the base class where the temp_* objects are not automatically
limited to the transaction's lifetime. (John Peacock)
Added Gavin Carr's greylisting plugin
Renamed config/ to config.sample/
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)
earlytalker and resolvable_fromhost - short circuit test if
whitelistclient is set. (Michael Toren)
check_badmailfrom - Do not say why a given message is denied.
(Michael Toren)

Fix warning in count_unrecognized_commands plugin (thanks to spaze
and Roger Walker)
Improve error messages from the Postfix module (Erik I. Bolsø,
<knan at mo.himolde.no>)
make the maildir plugin record who the message was to (with a bit of improvements
this could make a decent local delivery plugin)
Pass extra "stuff" to HELO/EHLO callbacks (to make it easier to
support SMTP extensions)
Renamed the *HARD return codes to DENY_DISCONNECT and
DENYSOFT_DISCONNECT (DENYSOFT_DISCONNECT is new)
Mail::Address does RFC822 addresses, we need SMTP addresses.
Replace Mail::Address with Peter J. Holzer's Qpsmtpd::Address module.
Don't keep adding ip addresses to the process status line ($0) when
running under PPerl.
Include the date and time the session started in the process status line.
Add "plugin/virus/uvscan" - McAfee commandline virus scanner
Inbound connections logged as soon as the remote host address is known
when running under tcpserver.
Add Qpsmtpd::Auth (authentication handlers! See plugins/auth/) (John Peacock)
Add a plugin hook for the DATA command
earlytalker -
+ optionally react to an earlytalker by denying all MAIL-FROM commands
rather than issuing a 4xx/5xx greeting and disconnecting. (Mark
Powell)
+ initial "awkward silence" period now configurable (Mark Powell)
+ DENY/DENYSOFT now configurable
Move relay flag to connection object (John Peacock):

SpamAssassin plugin Outlook compatibility fix (Thanks to Gergely Risko)
0.27 - 2004/03/10
Support for unix sockets in the spamassassin plugin (requires SA
2.60 or higher). Thanks to John Peacock!
Modified the dnsbl plugin to better support both A and TXT records and
support all of the RBLSMTPD functionality. (Thanks to Mark Powell)
reject bare carriage-returns in addition to the bare line-feeds
(based on a patch from Robert James Kaes, thanks!)
Bugfix to the count_unrecognized_commands plugin so it works
under PPerl (it wasn't resetting the count properly).
reset_transaction is called after disconnect plugins are called so
the Transaction objects DESTROY method is called. (Thanks to Robert
James Kaes <rjkaes@flarenet.com>)
Made the SpamAssassin plugin work with SA 2.6+ (thanks to numerous
contributors, thanks everyone!). Note that for now it's not
including the Spam: headers with the score explained. For that use
the spamassassin_spamc plugin from http://projects.bluefeet.net/
(for now).
Added Postfix queue plugin thanks to Peter J Holzer!
Took out the last "exit" call from the SMTP object; the "transport"
module ("TcpServer", "SelectServer") needs to do the right thing in
it's disconnect method.
Update the SPF plugin (Philip Gladstone, philip@gladstonefamily.net):
* Integrated with Mail::SPF::Query 1.991
* Don't do SPF processing when you are acting as a relay system
* Remove the MX changes as they are now inside Mail::SPF::Query
Take out Data::Dumper to save a few bytes of memory
Say Received: ... via ESMTP instead of via SMTP when the client
speaks ESMTP. (Hoping this can be a useful SpamAssassin rule).

check_badmailfrom
Use $ENV{QMAIL} to override /var/qmail for where to find the
control/ directory.
Enable "earlytalker" in the default plugins config
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.
Added SPF, sender permitted from, plugin
More minor changes and probably a few big ones that we missed adding here :-)
0.26 - 2003/06/11
Add queue/smtp-forward plugin (Matt Sergeant)
Add documentation to Qpsmtpd::Transaction (Matt Sergeant)
Fix bug in dnsbl that made it sometimes ignore "hits" (thanks to
James H. Thompson <jht@lava.net>)
Fix bug hiding the error message when an existing configuration file
isn't readable.
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.
Filter out all uncommon characters from the remote_host
setting. (thanks to Frank Denis / Jedi/Sector One for the hint).
Added a check for the spool_dir having mode 0700.
Don't break under taint mode on OpenBSD. (thanks to Frank Denis /
Jedi/Sector One)
Have the qmail-queue plugin add the message-id to the "Queued!"
message we send back to the client (to help those odd sendmail using
people debug their logs)
Set the process name to "qpsmtpd [1.2.3.4 : host.name.tld]"
Fixed timeout bug when the client sent DATA and then stopped before
sending the next line. (Gergely Risko <risko@risko.hu>)
unrecognized_command hook and a count_unrecognized_commands
plugin. (Rasjid Wilcox)
earlytalker plugin. Deny the connection if the client talks
before we show our SMTP banner. (From Devin Carraway)
Patch Qpsmtpd::SMTP to allow connect plugins to give DENY and
DENYSOFT return codes. Based on patch from Devin Carraway.
Support morercpthosts.cdb
config now takes an extra "type" parameter. If it's "map" then a
reference to a tied hash will be returned.
0.25 - 2003/03/18
Use the proper RFC2822 date format in the Received headers. (Somehow
I had convinced myself that ISO8601 dates were okay). Thanks to
Kee Hinckley <nazgul@somewhere.com>.
Print the date in the local timezone instead of in -0000. (Not
entirely convinced this is a good idea)
Lots of changes from Rasjid Wilcox <rasjidw@openminddev.net>:
Fix error handling in queue/qmail-queue. (Rasjid)
Add option to queue/qmail-queue to specify an alternate qmail-queue
location. (Rasjid)
Add support for the QMAILQUEUE environment variable. (Rasjid)
PPerl compatibility (yay!) (Rasjid)
Allow mail to <abuse> and <postmaster> to go through. (Rasjid)
Add "deny" hook that gets called when another hook returns DENY or
DENYSOFT. (Rasjid)

list specified in F<badhelo>. (For example aol.com or yahoo.com)
(Devin Carraway)
0.20 - 2002/12/09
Fix the "too many dots in the beginning of the line" bug.
Add munge_subject_threshold and reject_threshold options to the
spamassassin plugin. Add documentation to the spamassassin plugin.
Add -p to mkdir in log/run (Rasjid Wilcox <rasjidw@openminddev.net>)
clamav plugin, thanks to Matt Sergeant, matt@sergeant.org.
Enabling this might require you to increase your "softlimit" in
the run file. http://www.clamav.org/
Make the spamassassin plugin not stop the next content plugins from
running.
Store hooks runtime config globally so they will work within the
transaction objects too.
content_log plugin - log the content of all mails for
debugging. Robert Spier <robert@perl.org>.
http_config plugin - get configuration via http
plugins can take arguments via their line in the "plugins" file
make the quit_fortune plugin check that the fortune program exists
0.12 - 2002/10/17
Better error messages when a plugin fails
Remove some debug messages in the log
Fix NOOP command with perl 5.6.
Better installation instructions and error message when no plugin
allowed or denied relaying (thanks to Lars Rander
<lrNOSPAM@rander.dk>).
Use /usr/bin/perl instead of the non-standard /home/perl/bin/perl
0.11 - 2002/10/09
Make a "queue" plugin hook and move the qmail-queue functionality
to plugins/queue/qmail-queue. This allows you to make qpsmtpd
delivery mail via smtp or lmtp or into a database or whatever you want.
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.
Make klez filter run for mails bigger than 220KB; they are sometimes
bigger than that.
Avoid "use of uninitialized variable" warning when the "MAIL" or the
"RCPT" command is executed without a parameter.
Compatibility with perl 5.5.3.
Fix "Could not print" error message in the TcpServer object. (Thanks
to Ross Mueller <ross@visual.com>)
dnsbl plugin queues lookups in the background upon connect but
doesn't block for the results until they are needed, greatly
speeding up connection times. Also fix a typo in the dnsbl plugin
so it'll actually work(!).
check_badmailfrom and check_badrcptto plugins (Jim Winstead
<jimw@trainedmonkey.com>)
Better RFC conformance. (Reset transactions after the DATA command and
when the MAIL command is being done)
0.10 - 2002/09/08
New object oriented internals
Very flexible plugin
All functionality not core to SMTP moved to plugins
Can accept mails as large as your file system will allow (instead of
up to as much memory you would allow qpsmtpd to eat).
