The SOSDG and AHBL publish custom rule files for use in SpamAssassin. There are two ways to access these rules:
Using sa-update
You can run the following command to download and import our SpamAssassin rules:
/usr/bin/sa-update --allowplugins --channel sa.sosdg.org --nogpg
The rules will then (usually) be imported into /var/lib/spamassassin, where your system will begin using them. We recommend updating once per day, which you can do using crontab.
Download from the website
The rules are available for viewing and download at:
http://svn.sosdg.org/svn/sa-rules/
Please do not update from this URL, as it is a waste of resources if the files have not changed. Please use sa-update instead.
