I've implemented this, and posted the patches quite a while ago.  Basically
I set up a dbm database for each mailing list with the Message-Id as the
key with the number of messages received as data (bouncing the message if
the count is non-zero).

I've been considering changing the data to keep all the Received: headers
instead of the count.  This would allow me to go back to see where SPAM
came through that managed to get through the filters.
