I’ve been getting the duplicates too and also haven’t said anything for the same reasons. I did check the “List-" headers to see if I was getting a copy from cctech, but it’s not coming from there. I suspect what’s happening is the cctech is forwarding to cctalk, or has cctalk as a subscriber, and the cctalk list is not checking or storing the Message-ID to prevent duplicate messages.

Like you, I’m not an expert on mailman. The last time I ran a mailing list I used procmail’s SmartList.
