Look up "SpamAssassin".
If you are somewhat adept at tweaking tools like sendmail look up the
term "greylisting" and see if that process fits into your requirements.
Personally I prefer to use SpamAssassin with a simple procmail setup
rather than one of the milters. Their default installations seem to
be heavy handed and seem to obscure the SpamAssassin scoring.
If you do select SpamAssassin you might find some interesting rule
sets at the SpamAssassin RulesEmporium. (Although those have not
been updated much in the recent couple years. They just seem to work
well enough in most cases.) Also visit the SpamAssassin wiki and check
out the plugins.

to annoy some twits on this list. Then I decided to be polite
for a change. Of course, I did leave you a lot of homework to
do. Your needs are not my needs or anyone else's needs. Your
spam is not my spam, necessarily. So some hand tailoring will
be required of ANY solution.)
