18 September 2005 - Apache Spamassassin 3.1.0 Released
Apache SpamAssassin 3.1.0 has been released! SpamAssassin 3.1.0 is a major update. SpamAssassin is a mail filter which uses advanced statistical and heuristic tests to identify spam (also known as unsolicited bulk email).
Highlights of the release
-------------------------
- Apache preforking algorithm adopted; number of spamd child processes is now scaled, according to demand. This provides better VM behaviour when not under peak load.
- added PostgreSQL, MySQL 4.1+, and local SDBM file Bayes storage modules. SQL storage is now recommended for Bayes, instead of DB_File. NDBM_File support has been dropped due to a major bug in that module.
- detect legitimate SMTP AUTH submission, to avoid false positives on Dynablock-style rules.
- new plugins: DomainKeys (off by default), MIMEHeader: a new plugin to perform tests against header in internal MIME structure, ReplaceTags: plugin by Felix Bauer to support fuzzy text matching, WhiteListSubject: plugin added to support user whitelists by Subject header.
- Razor: disable Razor2 support by default per our policy, since the service is not free for non-personal use.It's trivial to reenable (by editing '/etc/mail/spamassassin/v310.pre').
- DCC: disable DCC for similar reasons, due to new license terms.
- Net::DNS bug: high load caused answer packets to be mixed up and delivered as answers to the wrong request, causing false positives.worked around.
- DNSBL lookups and other DNS operations are now more efficient, by using a custom single-socket event-based model instead of Net::DNS.
