I've cut out a vast majority of my spam by using the blackhole lists.
These lines are from /etc/mail/sendmail.mc:
FEATURE(`dnsbl', `relays.visi.com')dnl
FEATURE(`dnsbl', `bl.spamcop.net')dnl
FEATURE(`dnsbl', `relays.ordb.org')dnl
With these added, I drop 15-20% of my mail each week. At work we use
just the visi and ordb addresses are we were targetted by an open relay
a few weeks ago that we caught. We dropped about 300K messages before
we had the firewall blocks in place. That relay is now closed.

Here's my /etc/mail/access file.
# Check the /usr/share/doc/sendmail-8.11.2/README.cf file for a description

# The /usr/share/doc/sendmail-8.11.2/README.cf is part of the sendmail-doc

# by default we allow relaying from localhost...
