I just wanted to close this old topic with a thanks to Bryan Carbonnell (and anyone else) who successfully diagnosed the issue of mail duplication as mis-configured Outlook rules rather than a problem with mailman processing CC, reply-to, etc..
Thanks to anyone who responded. I'll go flog myself once for every person who's time has been wasted here. :) Tony Bryan Carbonnell wrote: > 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.
