    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.
