I'll do some research if I get time today but I'm fairly sure something
is borked with this spam filtering. Looking through the code I can see
that if a header is not found its not supposed to return a spam match.
The other thing I've noticed is that owner's don't seem to get spam
scanned. Still, our behaviour was that

KNOWN_SPAMMERS = [('X-Spam-Status','Yes')]

caused all emails from non-owners to be silently discarded.

At this stage I'm following the advice by not using KNOWN_SPAMMERS and
concentrating on per list measures. Thanks for your help.
