A few days ago in one of my Mailman 2.1.9 lists, a posting at 7AM was distributed to the members without problem. The mail is addressed to two lists, and both lists received, archived, and distributed the mail.
At 5PM one of the recipients must have forwarded the mail back to the lists. The RFC 822/2822 mail headers have the same Return-Path: From: To: lines as the original mail, and in addition there is a header line X-BeenThere: ... for one of the lists (i.e., the list to which this recipient is subscribed). The mail reached Mailman. I see in the Postfix logs status=bounced (mail forwarding loop for LISTNAME) I assume this is because there already is an X-BeenThere line for that list. The mail to the other Mailman list was accepted by Mailman and redistributed to that list. But I do not see a copy of the second distribution in the archives. I can see why Mailman accepted the 5PM mail - it had an authorized "From:" address. But why was the mail not archived? Because it was a duplicate mail? I would expect to have the archives contain a record of what was sent. Should Mailman have caught the duplicate posting? I have not been in contact with the recipient to determine exactly what he/she did. I would like to prevent this from occurring in the future. ---------------------------------------------------------------------- Barry S.
