Add support for multiple plugin directories, whose paths are given by the 'plugin_dirs' configuration. (Devin Carraway, Nick Leverton) Greylisting DBs may now be stored in a configured location, and are looked for by default in /var/lib/qpsmtpd/greylisting in addition to the previous locations relative to the qpsmtpd binary.

Fix the AUTH code to work correctly with TLS. Add hosts_allow plugin to support pre- and post-connection hooks as well as move --max-from-ip tests out of core (Hanno Hecker). Improve postfix-queue plugin to support the known processing flags (Hanno Hecker). Drop root privileges before loading plugins, rather than after. A few fixes to the clamdscan plugin (Dave Rolsky) Various minor fixes and improvements 0.31.1 - 2005/11/18 Add missing files to the distribution, oops... (Thanks Budi Ang!) (exim plugin, tls plugin, various sample configuration files) 0.31 - 2005/11/16 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 qpsmtpd-forkserver: --listen-address may now be given more than once, to request listening on multiple local addresses (Devin Carraway) (also: no more signal problems making qpsmtpd-forkserver crash/loop when forking). qpsmtpd-forkserver: add an option for writing a PID file (pjh) qpsmtpd-forkserver: set auxiliary groups (this is needed for the 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, forkserver will detach from the controlling terminal and daemonize itself (Devin Carraway) replace some fun smtp comments with boring ones. example patterns for badrcptto plugin - Gordon Rowell Extend require_resolvable_fromhost to include a configurable list of "impossible" addresses to combat spammer forging. (Hanno Hecker) Use qmail/control/smtpdgreeting if it exists, otherwise show the original qpsmtpd greeting (with version information). Apply slight variation on patch from Peter Holzer 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. Refactor Qpsmtpd::Address when disconncting with a temporary failure, return 421 rather than 450 or 451. (Peter J. Holzer) The unrecognized_command hook now uses DENY_DISCONNECT return for disconnecting the user. 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 Add plugable logging support include sample plugin which replicates the existing core code. Add OK hook. Add new logging plugin, logging/adaptive, which logs at different levels depending on whether the message was accepted/rejected. (See README.logging for information about the new logging system by John Peacock) plugins/auth/auth_ldap_bind - New plugin to authenticate against an LDAP database. Thanks to Elliot Foster 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 resident daemon. Store mail in memory up to a certain threshold (default 10k). Remove needless restriction on temp_file() to allow the spool directory path to include dots (as in ../) Fix off-by-one line numbers in warnings from plugins (thanks to Brian Grossman). Don't check the HELO host for rfc-ignorant compliance body_write patches from Brian Grossman Fix for corruption problem under Apache Update Apache::Qpsmtpd to work with the latest Apache/mod_perl 2.0 API. Fix various bucket issues. Replace $ENV{RELAYCLIENT} with $connection->relay_client in last plugin. Fix typo in qpsmtpd-forkserver commandline help 0.29 - 2005/03/03 Store entire incoming message in spool file (so that scanners can read 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) 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 (Michael Toren) Support qmail-smtpd's timeoutsmtpd config file Many improvements to the forking server (qpsmtpd-forkserver) Plugin testing framework (Matt) Added Apache::Qpsmtpd (Apache/mod_perl 2.0 connection handler) Allow for multiple instances of a single plugin by using plugin:0 notation (Robert) Fix CDB support so the server can work without it VRFY plugin support (Robert Spier) Added Makefile.PL etc to make it easier to build a package (Matt). Added Apache::Qpsmtpd to the distro. Make the distro follow the CPAN module style (Makefile.PL, MANIFEST, etc) Make the rhsbl plugin do DNS lookups in the background. (Mark Powell) Fix warning in count_unrecognized_commands plugin (thanks to spaze and Roger Walker) Improve error messages from the Postfix module (Erik I. Bolsø, ) 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 check_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): + add relay_client() method to Connection.pm + Remove $transaction->relaying() completely (due to popular demand) Split check_relay plugin into two plugins (John Peacock): + check_relay now fires on connect and sets relay_client() flag + rcpt_ok runs last of rcpt plugins and performs final OK/DENY + change default config/plugins to reflect new order 0.28 - 2004/06/05 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. Added a "queue/maildir" plugin for writing incoming mails to a maildir. Create temp files with permissions 0600 (thanks to Robert James Kaes again) Fix warning in check_badrcptto plugin (Thanks to Robert James Kaes) Proper "Log levels" with a configuration option $Include feature in config/plugins 0.27.1 - 2004/03/11 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 ) 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). Take out the X-SMTPD header. Add pod documentation and sanity checking of the config to check_badmailfrom Use $ENV{QMAIL} to override /var/qmail for where to find the control/ directory. Enable "check_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 ) 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 ) unrecognized_command hook and a count_unrecognized_commands plugin. (Rasjid Wilcox) check_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 . 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 : 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 and to go through. (Rasjid) Add "deny" hook that gets called when another hook returns DENY or DENYSOFT. (Rasjid) Add list of required modules to the README. Thanks to Skaag Argonius . Fix dnsbl plugin to give us all the results. (Patch from Matt Sergeant ) Disable identd lookups by passing -R to tcpserver. (Thanks to Matt) add plugin hooks for HELO and EHLO (Devin Carraway ) check_spamhelo plugin to deny mail from claimed senders from the list specified in F. (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 ) 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 . 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 ). 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 ) 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 ) 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 ) 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). 2002/09/08 Add klez_filter plugin Support more return codes for data_post Document data_post Add plugin name to the log entries when plugins use log() Add plugin_name method to the default plugin object. Improve error handling in the spamassassin plugin 2002/08/06 Spool message bodies to a tmp file so we can support HUGE messages API to read the message body (undocumented, subject to change) data_post hook (undocumented) SpamAssassin plugin (connects to spamd on localhost), see plugins/spamassassin 2002/07/15 DNS RBL and RHSBL support via plugins. More hooks. 2002/07/03 First (non functional) version of the new object oriented mail engine (0.10). Changes on the old v0.0x branch: 2002/05/09 Klez filter (thanks to Robert Spier) 2002/04/20 Bumped version number to 0.07 Support comments in configuration files (prefix the line with #) Support RELAYCLIENT like qmail-smtpd (thanks to Marius Kjeldahl and Zukka Zitting ) If the connection fails while in DATA we would just accept the message. Ouch! Thanks to Devin Carraway for the patch. 2002/01/26 Allow [1.2.3.4] for the hostname when checking if the dns resolves 2002/01/21 assorted fixes; getting dnsbl's to actually work fixing the maximum message size (databytes) stuff (thanks for the spot to Andrew Pam ) support and enable taint checking (thanks to Devin Carraway ) Make the MAIL FROM host dns check configurable. (thanks to Devin Carraway). Add more documentation to the README file.
