Sounds like you're describing the bounce_matching_headers option, from
Privacy Options -> Spam Filters, except that you want the default
action to be discard instead of hold.  I don't believe this is
possible at the moment, but it seems like it would be a simple thing
to add.  You could either add another option to the Spam Filters page,
perhaps discard_matching_headers, or just an option that toggled
whether posts matching bounce_matching_headers were held or discarded.

That would be handy to have a on a list by list basis, but there is a
site-wide configuration option, KNOWN_SPAMMERS, that you can set in
mm_cfg.py which looks to do exactly what you want.  You might want to
give that a try.  One of the comments in the SpamDetect.py file where
this spam filtering is done says "This needs to be made more
configurable and robust."  So it's on the list of things that will
happen when someone makes time to code it in.
