It appears they are replying to all, as in the few header samples I've seen, there are two instances of the group address (in the To and CC fields).
I have the setting checked to filter out duplicates, but still receiving complaints. Not sure how to handle this, as it seems to be on the user's end. C.

This will cause a duplicate if and only if the "nodups" setting of the recipient who is also directly addressed is off. In a default installation, this setting defaults to On for new subscribers, but the list admin can change it (new_member_options -> Filter out duplicate messages to list members (if possible)), and individual members can change their own settings Other possibilities include cross posts to multiple lists of which the recipient is a member, and duplication in the delivery chain after the post has left Mailman. The latter may be detectable by comparing the Received: header chain of the two received messages. Another possibility is duplication caused by filtering/sorting rules in the recipient's MUA. Depending on the exact rules, this could affect only some posts, but would not likely affect more than one user. -- Mark Sapiro <[email protected]> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
