HowTo Add extra rules to SpamAssassin

http://www.stearns.org has a weekly updated file to be used with SA to beef up its spam checking. Be warned this file is a few (currently four) megabytes and may slow up SA for usage.

Create the following file /bin/spam_update as root. I recommend copying this text, and then from a root console

  pico /bin/spam_update 

then paste these lines into the file. Press Ctrl-X and say Yes to save.

Make this file executable

  chmod 755 /bin/spam_update 

and now set it to run weekly by

  ln -s /bin/spam_update /etc/cron.weekly 

#!/bin/sh
