Unless I am notified of the contrary, I will assume that the problem with duplicate mail from LSTSRV-L@POLYGRAF has disappeared and was caused by a problem reported by the BITNIC LISTSERV (which, in the last 3 weeks, had been complaining about not being able to find license numbers in PEERS NAMES, all of which looked like the beginning of a valid number followed by binary trash, whose origin will probably remain forever unknown). If you do get duplicates in the future, please mail me a copy of the headers of the notes in question. Thanks, Eric
