What it is doing about them is to drop the message (it can't do anything
else). So if I send a message to adrian(dot)klaver(at)aklaver(dot)com,
pgsql-general(at)lists(dot)postgresql(dot)org you will get the copy sent directly
to your address (which won't have any List headers set), but not the
copy sent to pgsql-general(at)lists(dot)postgresql(dot)org(dot) So basically you don't
have any reliable way to detect that the message was sent to the
mailing-list (the best bet is probably to filter on the To: and Cc:
headers, but that may fail (both with false positives and false
negatives); some mailing-lists put a tag in the subject, but nobody
removes that for a private reply.

Maybe you like the way it works. I find it useless, because it does
exactly the opposite of what I would want it to do (but I know that
that's impossible).
