Oops, that should be security/clamav. Where my mind is this morning...

Here's the setup we run, and it works incredibly well.
Sendmail
mail/p5-Mail-SpamAssassin
mail/spamass-milter
mail/spamass-rules
mail/spamass-rules_du_jour
sysutils/clamav (built with miltering)
Add to your .mc file:
INPUT_MAIL_FILTER(`clmilter',`S=local:/var/run/clamav/clmilter.sock, F=,
T=S:4m;R:4m')
INPUT_MAIL_FILTER(`spamassassin', `S=local:/var/run/spamass-milter.sock, F=,
T=C:15m;S:4m;R:4m;E:10m')
crontab nightly
/usr/local/bin/rules_du_jour
Make sure your ports tree is cron'ed to update regularly, have the freshclam
daemon running, and I'd strong suggest subscribing to the RSS feed at
http://www.freshports.org/sysutils/clamav
Just my 2 cents. ;)

Would I want to enable milter with clamav?
Depending on your needs, maybe. The clamav-milter lets sendmail reject
mail containing viruses immediately, rather than having to receive them and
then filter them later.
You should also investigate greylisting, which has very little downside and
is the most effective antispam measure I've seen yet.
Here's something I wrote on that a while back. It needs to be updated, but
it should give an idea:

The default delay introduced by milter-greylist is 30 minutes. From what
I've seen in log files, this could probably be reduced to even five minutes
and still be effective. Most spamware and viruses don't retry even once.
