I use sendmail with several milters that do pre-filtering before
delivery.  The least costly of the milters I use is milter-regex, and
here is an older sample of what it drops...

If the mail makes it through that milter it runs through milter-spamc,
which does nothing more than pass the mail off to spamd / spamassassin.
After that it hits milter-clamav for virus checking.  I try and do as
much dropping of mail using the regular expression milter though, as it's
the least costly in terms of system resources.

Hope this helps,
