Yes, but I wanted to comment on the issue so others could consider it. This
will bite others as they implement anti-spam policies.

Well, as more sites turn off relaying it will get somewhat better. Once a
big spammer gets your majordmo list, it will be more then one that goes
though and bounced.

: But doing this kind of thing requires actual bounce parsing; VERPs (or
: the Mj2 analogue) can't help you there.  Then again, most MTAs
: supporting those kinds of filters also use a reasonable bounce format.

Yes, most do.
