Jay, you need to have SPF records for your domain. This will prevent
the spoofing you are seeing.

I should in fact.  

But am I incorrect in thinking that since the envelope address *was not
actually forged*, they wouldn't help here unless *Mailman* also processed
them?

(And alas, that article is itself complicated enough to tell me that I
need to do actual research on the issue, so it won't happen tonight. :-)

Cheers,
