Compuserve sends bounces back to the list (violation of RFC standards) instead of the owner-listname address (MAIL FROM) This is why that error message initially looks like a user quoted list headers to a novice listowner (which I'm not far beyond). Actually Listserv rejected the Compuserve error message (sent to the list) because it found the listname in the body ("Sender:", "From:" or "Reply-To:" field pointing to the list has been found in mail body. ) then sent that error/rejection to the owner. So you get the compuserve bounces, just in a confusing round-about way.
