You want to use a milter.  A milter is an external processes that
sendmail streams incoming messages through.  Arbitrary things can be to
the messages at that point, typically scanning for virii, lopping off
illegal attachments (.pif, etc..).  There are lots of milters available.

Sendmail will do this handily.  Just plug in spamcop support while your
at it and watch the SPAM bounce off your server.
