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 [EMAIL PROTECTED]; 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 [EMAIL PROTECTED]; 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.
