Mailman does not modify the Message-ID of list posts except in the case of anonymous lists. In that case, and in the case of a message wrapped for DMARC mitigation, the Message-ID of the anonymized message or the outer wrapping message is a Mailman generated id of the form <mailman.nnnn.tttt.pppp.LISTNAME@HOST> where nnnn is a serial number, tttt is the time in seconds since the epoch, and pppp is the pid of the IncomingRunner process. > I'm trying to trace disappearing posts from a couple of list members. > Their posts go through postfix, mailman reports the posts as > succesfully posted, and the posts show up in the list archives, but > not in the subscribers mailboxes. Is there anything in Mailman's bounce log? What does Postfix report about the outgoing posts? > I have a small list with about 20 members.

Because the recipient's MTA's are rejecting the post for DMARC policy reasons. > I grep postfix logs (/var/log/mail.log) for the sender's email > address, I see a message coming in, and postfix handing it off to > mailman post (full log excerpt at end of message): ... > Grepping for lines with a similar timestamp turns up half a dozen > bounce messages two seconds later, which may explains why those 6 > subscribers don't get the messages, but not the rest. The bounces may be for multiple recipients in the same domain. > Jul 9 07:52:54 ip-172-31-8-246 postfix/smtpd[5171]: connect from > localhost[127.0.0.1] > Jul 9 07:52:54 ip-172-31-8-246 postfix/smtpd[5171]: 88D3726A7D: > client=localhost[127.0.0.1] > Jul 9 07:52:54 ip-172-31-8-246 postfix/cleanup[5174]: 88D3726A7D: > message-id=<1404892372.90900.yahoomailba...@web163105.mail.bf1.yahoo.com> > Jul 9 07:52:54 ip-172-31-8-246 postfix/qmgr[1119]: 88D3726A7D: > from=<examplelist-boun...@example.com>, size=3672, nrcpt=1 (queue > active) What else do you see in the Postfix log with queue ID 88D3726A7D ?
