For mail sent to the list posting address or the list-owner address,
Mailman's header_filter_rules are applied before anything else.
Mailman's bounce_matching_headers (a misnomer because it's actually a
hold, not a bounce) are applied later to list posts (after member
tests) and not at all to list-owner mail.

Those are good suggestions, but in the case of the OP, the issue is
much simpler than that. Spam is sent directly to the list-bounces
address.

Yes.
