Yeah Outlook Express did that when it forwarded messages I forgot
the version - it screwed up spamassassin, I filed a bug, bug finally
got a workaround added.
File a bug with mailman and cyrus dev. teams, maybe they can
work around it. At least get it documented. And call Microsoft
tech support and complain. Microsoft does not charge for tech
support incidents where a bug is reported.

Subject: (off-topic) Outlook 2003 msgids causing odd email problems
I'm raising this here in case anyone else has either seen this
problem and has
any thoughts, or alternatively has experienced the fallout and is
wondering
why.
Over the last few weeks I've had complaints that email messages are going
astray. This has happened in Cyrus imapd on delivery, and in
Mailman, where
archiving of posts is sometimes broken.
After much scratching of head and tearing of hair, I have finally
found two
provable instances - one in Cyrus and one in Mailman - of replies
to messages
being sent using Microsoft Outlook Service Pack 2, where Outlook
has given
the reply the same message-id as the message it is replying to - in flat
violation of RFC{2}822. (In one case the original message, the
read-receipt
automatically generated by Outlook, the reply, and the forward of
the reply
sent when the reply didn't arrive, all had the same msg-id).
As far as I can tell this behaviour was introduced by SP2; the Web says
Outlook 2003 before that didn't add message-ids at all.
I've now set
duplicatesuppression no
in imapd.conf which seems to be addressing the problem of lmtpd
discarding the
``duplicate'' messages. Mailman is another issue.
I haven't seen any discussion of this problem on the Web: has anyone else
encountered it? Better yet, does anyone have a fix (on the
Microsoft side)?
