*** THIS IS A RELEASE CANDIDATE ONLY, NOT THE FINAL 3.1.0 RELEASE ***
SpamAssassin 3.1.0-rc2 is 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).
This is a release candidate, and NOT the general availability release
(yet.) We think it's pretty rock solid, however. ;) Please test it
out, and report any bugs to:
http://bugzilla.spamassassin.org
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.

Summary of major changes since 3.0.x
------------------------------------
- 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.
- Inclusion of sa-update script which will allow for updates of rules
and
scores in between code releases.
- 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 Advance Fee Fraud (419 scam) rules.
- removed use of the Storable module, due to several reported hangs on
SMP
Linux machines.
- Converted several rule/engine components into Plugins such as:
AccessDB, AWL, Pyzor, Razor2, DCC, Bayes AutoLearn Determination,
etc.
- 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.
- TextCat language guesser moved to a plugin. (This means
"ok_languages"
is no longer part of the core engine by default.)
- Razor: disable Razor2 support by default per our policy, since the
service is not free for non-personal use. It's trivial to reenable.
- 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

- add support for accreditation services, including Habeas v2.
- better URI parsing -- many evasion tricks now caught.
- URIBL lookups are prioritized based on the location in the message
the URI was found.
- mass-check now supports reusing realtime DNSBL hit results, and
sample-based
Bayes autolearning emulation, to reduce complexity.
- sa-learn, spamassassin and mass-check now have optional progress
bars.
- modify header ordering for DomainKeys compatibility, by placing
markup
headers at the top of the message instead at the bottom of the list.
- spamd/spamc now support remote Bayes training, and reporting spam.
- spamc now supports reading its flags from a configuration file using
the -F
switch, contributed by John Madden.
- added SPF-based whitelisting.
- Polish rules contributed by Radoslaw Stachowiak.
- many rule changes and additions.
