Inspection of the message headers may give some clues. In particular, it should show *where* the duplication was happening: the duplicates will have the early Received: headers identical, and differ in later ones. The earliest different one will probably reveal the source of the problem. One possible cause is a mail server accepting a message for onward transmission but failing to get its acknowledgement back in time, so the preceding server thinks the transmission failed, and retries. [I get the Digest, so I haen;t noticed any duplication]. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
