Actually, according to RFC822 you needn't put anything between list-name: and the ;. Obviously one wouldn't want to put all the names of the list there: the individual name(s) suffice. Perhaps it would be best to put a modified id in Sender like LSTSRV-L-REQUEST Or does this run afoul of the 8 character limit. Incidentally, how does listserv (in collaboration with MAILER possibly) get the mail for the userids that are names of lists. Since, for example, theorynt@ndsuvm1 is never logged on (it's not clear that such a id even exists -- at least to VM), what hack transfers mail destined for it to LISTSERV? Victor Miller
