Disclaimer
Custom or third-party rules described here are not part of the official SpamAssassin distribution. They may have a different license and are not from the Apache Software Foundation.
Available Custom Rulesets
Listed below are several custom rulesets that are available as "drop in" .cf files. To use these rules, just place the file in /etc/mail/spamassassin (if you use spamD, be sure to restart). Before running these rules please do the following:
- Read any extra info available with the rules, including the comments in the .cf files. 2. Check to make sure that the default scores in these rules fit your installation. You might want to modify scores. 3. Make sure to --lint the rules after loading them. 4. Test the new rulesets. Keep an eye on hits from the new rules to determine if the scoring is right for you.
Use at your own risk.
