As I mentioned in my response to Brad, I'm not even involved in the discussions where I'm getting the dupes. This would be an obvious source of duplication. I'm just another quiet recipient to the list (hehe, until now anyway) and there's no reason for me to be explicitly identified in the TO or CC. > Do the > duplicates appear twice in archives and/or digests?

No, only one copy of every post is in the archives and no one else is reporting dupes. > Other subscribers may not see this because their incoming MTA/MUA may > drop duplicate message-ids. As with most OSS projects there is a heavy bias away from Microsoft software, including Outlook which I use. Chances are slim that others in this OSS forum are using Outlook and thus their MUAs might be filtering away the problem. So I was suspecting my MUA. However, I do not get dupes when people in this mailman-users list CC the list but I do get some dupes from that group - obviously the same MTA/MUA tiers are involved. This is why I have been suspecting something in the list software that is different. Maybe there's a patch or addin that they've installed that corrupted this dupe-filtering code? That's what brought me here - Until now I've had no idea if this was an issue specific to that group or something that was introduced in the v2.1.5 code that you guys would know or want to know about.
