That's too bad, because amavisd-new is probably the best post-queue
filtering solution choice. You no longer need clamsmtp and you get
SpamAssassin invoked as perl modules, part of the same running perl
process. I would recommend that you reconsider amavisd-new.
I didn't see mention here [yet] of HELO checks. Among the cheapest and
safest spam blocks are reject_invalid_helo_hostname and
reject_non_fqdn_helo_hostname. Plus, you will see a lot of spam HELOs
containing your IP address. It's also reasonable to block HELOs with
your own domains (after whitelisting hosts that might legitimately use
such names as HELO), but I don't think you'll block a lot of spam with
those checks.
