#Here's what I did:
#  I use smrsh instead of /bin/sh as the "shell" invoked by sendmail
#      when (say) interpreting .forward files (security).
#  I weed out spam using RBL, DUL, and RSS.
#  The `delay checks' FEATURE ensures that the antispam checks
#      are done at the check_rcpt stage. More information about the - alleged-
#      spam (eg, the intended recipient) are logged this way.
#  I also consult my own access database, /etc/mail/access (for various
#      purposes).
#  I disable expn (security).
#  Finally, a very simple ruleset to reject obviously munged
#      MessageID's (spam).
