Release Notes: Bayes locking and concurrency issues have been fixed. Bayes expiration is now working, fixed. spamd now enables Bayes after auto-learning without restart. There is a safer way to attach spam messages, for broken email clients, using 'report_safe 2'. There are a few documentation cleanups.
Release Notes: Bayesian filtering: auto-learning, training the Bayesian filter automatically based on the results from traditional SpamAssassin diagnosis. A much-improved rule set, with accuracy measured at 97.77% without network or Bayes tests, 98.36% with, and a new default markup format, where the message is encapsulated as a MIME part, with a preview and the spam report in the main part of the message. This should be considered a beta release.
Release Notes: This release fixes a few high-priority bugs already fixed in the (as yet unreleased) 2.50, including a buffer overflow if you use "spamc -B". Note that this is not 2.50, which offers Bayesian filtering, etc. These bugs are already fixed in the 2.50 CVS tree, but that is not yet ready for release. This is a stable maintenance release only.
Release Notes: The AWL change has been reverted; instead of decreasing the AWL bias gradually to allow frequently seen addresses to get into the "nonspam" area, it now behaves like 2.31 did, in that the AWL simply represents the long term average score from that correspondent. A core dump bug in spamd has been worked around, except for the "-m" switch. The "-m" switch relies on signal handling in the Perl interpreter, which seems to have some bugs that cannot be worked around reliably on some platforms, so its use is no longer recommended.
Release Notes: This release includes many new rules, and From address forgery can no longer subvert whitelisting. Please read the INSTALL file if you plan to upgrade from a version prior to 2.40, or else you risk losing mail.
Release Notes: New rules, faster execution, and new options.
Release Notes: Some aberrant scores from the previous release were fixed, as were some minor bugs.
Release Notes: An update to auto-whitelisting, better email parsing, refined rules, and bugfixes were added.
Release Notes: In this release, whitelist_to now works with multiple To or CC addresses, ^Ms in headers are now ignored, for compatibility with MUAs and filtering packages, spamd is now cleaning defunct processes on some platforms, and all-caps SUBJECT/Subject headers are now handled correctly.
Release Notes: Mail::Audit, Mail::Internet, and Net::SMTP dependencies have been removed. Auto-whitelisting was added so that regular correspondents who send non-spam mail are eventually added to a personal whitelist. A new spam-phrase analysis module was added. spamc/spamd commandline argument semantics were changed. The config file was split up into a directory and config locations are now legal according to the Filesystem Hierarchy Standard (FHS). Many new tests and a new GA score set were added.
