I'm running a small mailman-based mailing list on a Linux server, and the only spam posts we seem to get are in russian. They are automatically moderated of course, since they're not subscribed to the list, but it's still a hassle to have to always go in and clear out the moderation queue. Is there any way I can set up a simple filter that based on certain keywords will just junk incoming mails before mailman sees/processes them?
EDIT: Here is a sample mail
