Custom Plugins
Disclaimer
Custom or third-party plugins described here are not part of the official SpamAssassin distribution. They may have a different license and are not from the Apache Software Foundation.
Please add links to third-party SA plugins to the bottom of this page. Note that only SpamAssassin 3.0.0 or later can use these. To use these, just place the file(s) in /etc/mail/spamassassin (if you use spamd, be sure to restart); SpamAssassin will need at least 1 rule file (ending in .cf) to load the plugin, and that will typically use a loadplugin line to load a .pm file containing the plugin's perl code.
FYI: The .pm file can be kept in /etc/mail/spamassassin, too.
Before running these plugins please do the following:
- Read any extra info available with the plugins, including the comments in the .cf files, or the POD documentation in the .pm file.
- Check to make sure that the default scores fit your installation. You might want to modify scores.
- Make sure to --lint the rules after loading them.
- Test the new plugin. Keep an eye on hits from the new rules to determine if the scoring is right for you.
Use at your own risk.

DSPAM
When using dspam in conjuction with SpamAssassin and amavisd-new, amavisd-new automatically has dspam calculate the probabability of a message being HAM/SPAM and then insert headers. If you have SA installed, the dspam information goes to waste. That is unless you take advantage of this plugin.
