Release Notes: A report can now be stored in the headers, in a terse format, the MX test on the From field is now working, pure-attachment mails are now avoided, and SQL setup statement has been fixed. A patch for qmail support, and new GA-evolved scores have been added, along with lots of new tests.
Release Notes: A workaround for a memory leak due to a Perl bug was made. Razor 1.13 is now supported, and user scores can now be loaded from an SQL database. Whitelist and blacklists patterns have been added. RBL checks were not being run in a consistent manner, so this problem was also fixed.
Release Notes: spamd/spamc client-server tools, a new scoring system (using scores optimised by a genetic algorithm), support for non-integer scores, support for the latest release of Razor system, and a mass-check system (to allow users to contribute back scores for their mail spools to help in new score evolution) was added.
Release Notes: Some new tests were added, as well as MIME header decoding. Some tests were rescored, based on statistical analysis of a large mail spool, and several tests were fixed to provide better scoring. spamassassin -d now only removes body lines inside the report, not in the mail in general. Memory usage has been reduced on really big mails.
Release Notes: Fixes for config file-finding code and the README, "spamtrap" support (where an alias can be set up with SpamAssassin to immediately blacklist any spams that arrive there), a "whitelist" (where emails from certain addresses will always be permitted), a new Sircam check, some tests for new spammer tricks, and a new -d switch which removes SpamAssassin markup from a mail message.
Release Notes: ORBS check has been changed to ORDB check. Patterns have been fixed to avoid some false positives. Auto-reporting code has been added, so that if a mail gets a large number of hits, it will automatically be reported. Support has been added for reporting spam (-r switch), as well as the ability to match against the full message or all headers. Support for delivering to MAIL, DEFAULT, etc. has been added, giving better procmail support.
Release Notes: Razor support, fixes for RBL support, some new anti-porn-spam patterns, a fix for the RBL domain to use mail-abuse.org, and more tests.
