Oops, sorry for the irrelevant thread inclusion. I guess emacs adds the References header after a message is sent is sent? In my setup, the easiest way to post to a mailing list is to reply to an existing message (since I subscribe to each list under a different email address). I tried to start a new thread by deleting the In-Reply-To and header which was all I saw, but I guess the References header got inserted later... David
