This isn't really a place to ask this... but you already seem to know
that. Thus:
How you integrate SA and clamav into your system depends on what mail
server you're running. The easiest way (I think) is to do this through
Procmail (which still requires some mail server support). Procmail
lets you define rules for handling messages. E.g., you can have a rule
for all messages that scans them with clamav and spamassassin, and
then a rule for messages that SA marks as spam (i.e., adds a header
like X-Spam: Yes or somesuch) to be discarded.

My suggestion above works for this as well. You can use procmail rules
along with spamassassin to pre-filter posts to your list and discard
any that are blatantly spam. That said, the fact that you're getting
the notifications, rather than getting spammy posts to the list, means
that mailman is doing its job in this regard. Any improvements you
make will just result in less spam for you.
