It seems I am getting duplicate messages from mailman v2.1.5 when senders send both TO and CC to the list. For some reason no one else in the list is acknowledging this issue so I look like an idiot complaining about it, but I'm seeing several instances of it per day.
I'm seeing duplicates too, reading in Microsoft Entourage (which differs greatly from Outlook). I haven't taken the time to analyze them (delete works fine). Since some of them are in threads crossposted to users and developers lists, I see four copies of those.
Two copies of a message with this Message-Id: Message-Id: 1146489146.11009.13.camel@geddy.wooz.org Message-Id: 1146489146.11009.13.camel@geddy.wooz.org reached me through the developers list (based on the List-xx headers)
This is the one in which Barry started out "I agree that we need a lot more data"
And two more copies came via the users list.
Tony, I think you need to review your Outlook rules.
My duplications are produced in our mail server's mail sorting process, and the key is the presence of prefixes for both -users and -developers in the Subject: lines of the problem messages.
Considering only the two copies from the Developers list, the divergence appears to be in our mail processing. The messages arrived our our world-facing machine with the same Exim Id:
Received: from smtp-vbr8.xs4all.nl ([194.109.24.28]:3979) by entiat.olympus.net with esmtp (Exim 4.42) id 1FaYCW-0006pK-O1 for jwblist@loricamail.com; Mon, 01 May 2006 06:12:33 -0700
and
Received: from smtp-vbr8.xs4all.nl ([194.109.24.28]:3979) by entiat.olympus.net with esmtp (Exim 4.42) id 1FaYCW-0006pK-O1 for jwblist@loricamail.com; Mon, 01 May 2006 06:12:33 -0700
(ie, the same).
And having looked at the server logs, I now know what is happening in my case. I have our mail processing sort list mail into IMAP folders based on--in the case of these lists--the presence of the subject prefix, and these messages have prefixes for both lists in the Subject: header.
So my copy for -users gets sorted into my folders for -users and for -developers, and my copy for -developers gets sorted into -users and into -developers.
Note: the next revision of our mail processing will allow sorting based on arbitrary headers--the List- headers for example.
