The core distribution consists of command line tools to perform filtering along with Mail::SpamAssassin, a set of perl modules which allow SpamAssassin to be used in a wide range of products.

Please create a local copy of the report_template text in a file named something like /etc/mail/spamassassin/10_local_report.cf, and modify it to provide your tech support desk's contact information, instead of the default. Otherwise your users will be confused, and some may ultimately contact the SpamAssassin development team, which is not appreciated; we cannot help them with whitelisting/blacklisting/customisation of settings at your site, after all. The default report text can be found in the file rules/10_misc.cf.

The currently selected mirror is http://apache.cbn.net.id. If you encounter a problem with this mirror, please select another mirror. If all mirrors are failing, there are backup mirrors (at the end of the mirrors list) that should be available.

You may also consult the complete list of mirrors.

• SpamAssassin(tm) in tar.gz format. (signatures: GPG MD5 SHA1)

• Michael Moncur has written a very good configuration tool which will generate a local.cf or user_prefs file for you, once you fill out a few simple questions.

• MacOS X users: Ben Trott of MovableType has written a good how-to on installing SpamAssassin on OSX. A possibly more up-to-date article is 'Fighting Spam on Mac OS X Server' at Apple Developer Connection.

Nightly snapshots of the latest SVN trunk code can be downloaded from cvs.apache.org. These are built nightly from the SVN repository, and may be unstable!

If you want to use GPG to verify the downloads listed above, please use the SpamAssassin Release GPG Key:

pub  1024D/265FA05B 2003-06-09 SpamAssassin Signing Key <release@spamassassin.org>
     Key fingerprint = 26C9 00A4 6DD4 0CD5 AD24  F6D7 DEE0 1987 265F A05B

Note: GnuPG 1.4.0, and possibly 1.3.x versions, seem to have problems verifying certain signature files, including the type as used for SpamAssassin releases. If you are running an affected version, please verify the code using both MD5 and SHA1 sum values instead.

Old Apache-licensed versions (from version 3.0.0 on) can be downloaded from archive.apache.org. Older, Perl-licensed versions can be found via CPAN.
