Do you know about the DCC, SpamAssassin, Brightmail, or Postini? I
may be somewhat biased, but I think all of those are reasonably reliable
and reasonable. (I've some reservations about SpamAssassin, but only
because I wonder about Perl for filtering more than 50,000 messages/day.)
Just as an anecdotal point -- we filter ~ 2 million messages a day through
MIMEDefang and SpamAssassin. Based on reports from users, we see between
2-5 false positives a day.
