That's the trick, of course: how to catch enough of them without any
false positives.
I think I have it narrowed in fairly tight. I think I'm on the
conservative side enough that variations in bounces are more likely
to be skipped than bounce a good address.
However, I would like to see any message that anyone thinks might
trigger a false positive.

I don't know how safe that is. By running it on the list sender address,
you know you'll only get bounces from that list's postings. I would
tend to NOT put it on a general address that receives all sorts of messages
because I definitely think that would greatly increase the chances of
a bogus match. As I said, putting it on the list sender address
will pretty much limit the messages to real bounces from that one list.

It also needs a configuration option for the approval address. This
is where the majordomo results are send back to. Defaults to
listname-approval.

That's what I ended up with. I called it autobounce.cf
