B-I-N-G-O (I think)! The smtp-failure log has entries like: Apr 27 01:20:09 2006 (12765) All recipients refused: {'[EMAIL PROTECTED]': (550, 'Verification failed for <[EMAIL PROTECTED]>\nNo Such User Here\nSender verify failed')}, msgid: <[EMAIL PROTECTED] Apr 27 01:20:09 2006 (12765) delivery to [EMAIL PROTECTED] failed with code 550: Verification failed for <[EMAIL PROTECTED]> No Such User Here Sender verify failed Seems like SMTP is rejecting mail that is supposed to have come from "[EMAIL PROTECTED]". That address does not - and never did - exist as a real account as far as I know. In the past (when all was working) the server must have been configured with less stringent sender verification, or some exception for "mailman-" addresses. Sure enough, if I temporarily create an account "[EMAIL PROTECTED]", everything starts working as expected. Not sure if that's the "proper" solution...I'm guessing I don't really need the account, but rather an SMTP rule of some sort to allow the necessary sender addresses. Now I have the ammunition I need to confront my host again...THANKS!!
