No, those are Exim's local IDs, assigned by the list server host. Those are distinct from RFc 5322 Message-IDs, which are the closest thing to uniquely identify a message. So from the above it cannot be concluded that Peter's system sent the message twice: it might have, but it might equally have been the fault of the list server. FWIW, I am _not_ seeing any duplicates on this list, but I am currently struggling with dupes on another one: http://minnie.tuhs.org/mailman/listinfo/tuhs -- Please don't Cc: me privately on mailing lists and Usenet, if you also post the followup to the list or newsgroup.
