I don't think you can change that Return-path:, but even if you could,
I wouldn't.  Error messages sent to the list itself? Ridiculous!
Why doesn't he gripe about the From: and Sender: being different, and
Reply-to: *can* be different from the other three.

You day you don't know who the subscriber is, but the guy you are talking
to is at turbonet.com.  Do you not have any subscribers at turbonet.com.
IF you have any, assume this stuff applies to all of them, and tell *them*
that if this "chalenge" stuff doesn't stop their subs will be deleted for
cause, they will then be free to resubscribe when they get a different IP.
And put turbonet.com in your Filter= in the list header.

I see no reason why you should have to put up with this nonsense.
