ACK but ..

any 'proper' MLM that wants to succeed in the Wide World is *usually*
better-off if it has acceptable and unique credentials of its own.

tahini, for example, shows the submitting poster in a 'From' header, and
we see each successive envelope-from of earlier stages.

But the critical element - the 'last mile' envelope-from, is that of
tahini, not that of the submitting poster or the intervening MTA.

This is where I believe the OP's 'mailing list' config is at variance
with BCP - not the server.

I hear you.

But the other thing we don't know is how accurately the OP used those
terms.

MY supposition is that IF he had an accurate understanding of the terms,
he would have not had the problem in the first place.

.. and pehaps he *has* twigged to all that and fixed it.

Notice his absence of late..
