Sendmail has a mail filter interface.

Have a look at MIMEDefang, which uses this interface to remove
dangerous attachments.  MIMEDefang will also run SpamAssassin
and a variety of virus scanners (including Clam Antivirus if
you want to stay with just free software).

Because MIMEDefang is a mail filter, the usual local delivery
mechanism is used -- handy as users don't need to change procmail
rules and sysadms don't need to stuff about with adding rules to
the delivery chain into IMAP databases.

Glen
