I haven't been following this thread too carefully, but a couple of
things clicked together based on some duplicate issues I've seen with
Just to recap the details as I recall them
1) You are the only one seeing the duplicate e-mails
2) You are using Outlook.
3) Duplicate e-mails are idendical down to the header level.
4) Only happens on 1 list.
5) Only happens when the list is in the CC header.
If all the above are correct, check your Outlook rules. Outlook may be
the cause of the duplicates.
I've spent a TON of time trying to diagnose this for one user and it
turned out it was her Outlook rules that caused the duplicate.
I don't use Outlook myself, but try disabling the rule for a while and
see if the duplicates still happen. If not, then recreate the rule.
I know this isn't Mailman related, but I think that this may be a good
cause for the archive.
