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 your SpamAssassin plugin directory, which may be /usr/share/perl5/Mail/SpamAssassin/Plugin/ (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.

You can also keep the plugin's .pm file in your /etc/mail/spamassassin/ or /etc/spamassassin/ directory, but you need to specify the plugin's file name as the second argument to loadplugin. For example, a plugin named Mail::SpamAssassin::Plugin::MyPlugin with a filename of myplugin.pm: loadplugin Mail::SpamAssassin::Plugin::MyPlugin myplugin.pm

Before running these plugins please do the following:

  1. Read any extra info available with the plugins, including the comments in the .cf files, or the POD documentation in the .pm file.
  2. Check to make sure that the default scores fit your installation. You might want to modify scores.
  3. Make sure to --lint the rules after loading them.
  4. 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.

Mail::SpamAssassin::Plugin::LDAPfilter
Mail::SpamAssassin::Plugin::LDAPfilter provides LDAP-based blacklist and whitelist filtering capabilities to SpamAssassin 3.x installs. Standard elements from the SMTP session and the RFC822 message are parsed out and searches are submitted to an LDAP server, and scorable responses are returend for any matches. For example, if a message contains a parseable domain name, the domain name will be used as a search key against the LDAP filters, and if a match is found the plugin will return a scorable marker, which could either be positive (blacklist) or negative (whitelist).

SAGrey
SAGrey is a two-phased greylist tool for use inside spamassassin. It first looks to see if the score of the current message exceeds the current "spam" threshold value, and if so then it looks to see if the message sender's email and IP address tuple are already known to the auto-whitelist (AWL) repository. If the message exceeds the spam score and the sender is unknown to spamassassin, SAGrey assumes that this is one-time spam from a throwaway or zombie account, and fires accordingly.
This is badly named, as it does not actually do greylisting.
