This was very useful in explaining why MM3 (3.3.9) accepted the problem post and attributed it to my address, even when seeing the bounce+ address as a different sender. Thank you for taking the time to reply.
Are you saying that the bounce+... address ends up as a nonmember of the list you are sending to. I don't think that should happen.
Yes, that is what is happening, but only for messages from the steve@stevebrown address. I can send a screenshot and a .txt of the headers (of the message after sent back to me from MM3 and long!) but didn't see a way to do that on the archive page. Do I need to post from my gmail address?
One clue I hadn't spotted before was a bodyhash_mismatch warning in the headers. No idea where that came from. Doesn't appear in emails from me to other addresses.
