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 <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
