Over the last month or two I have been going over the headers myself and the headers on each copy of the mails are exactly the same: same Received path and time stamps, and same Message-ID (!!). The only pattern between what generates dupes and what does not is that the list address is in the CC of duped mails - but only on that list, not in this mailman-users list. :(
Please allow me a few days to pursue the MTA route and I'll post a note here to let you know if I find anything. Based on your comments and info from the other list I'm fairly convinced that I shouldn't be wasting any more of your collective time. But I will let you know what I find out.
Thank you kindly for your dedicated interest.
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 my users.
Just to recap the details as I recall them
- You are the only one seeing the duplicate e-mails
- You are using Outlook.
- Duplicate e-mails are idendical down to the header level.
- Only happens on 1 list.
- 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.
