We are already using ok_locales, but it does not score all of the mail and
if it scores, the few points at all are not enough to identify it as spam
(since bayes still scores negative). I already trained bayes with hundreds
of mails, but it still doesn't recognize this ndr as spam.

That sounds quite nice, but the documentation says the plugin looks for the
specified mta relay in the Received: header of the mail. If found, it is not
marked as an invalid bounce. This may be a problem because most bounces do
have header information that looks like this (where
Merkur.intranet.jam-software.com is our mta):
