FWIW Bogofilter uses SpamAssassin internally. Experience indicates that the FREE SpamAssassin (already part of FC distros) and the Spam Assassin Rules Emporium rule sets, carefully user selected as needed, are more effective than Bogofilter, which I understand is (quite) not free.
Correction - my understanding was incorrect it appears. Nonetheless, SA and SARE works better based on sa users list comments. {^_^}
