I attempted to run 'vacation' on one of my Un*x accounts to see what kind of header it generates, as I had read something about a 'Precedence: junk' tag in the help files. Unfortunately, instead of the expected message I got a nastygram saying that there was an unknown imail error 139, that the core was dumped followed a memory fault and that a copy of the offending message would follow (which it did). In addition I got a message with empty body whose subject said I was in vacation and whose header contained no particular tag, other than the usual 'From:' and 'To:'. So, it looks like there is no such tag in the current version of of the program. I sincerely doubt anybody will be able to convince the Un*x folks to update their program in this fashion just for the sake of this IBM heresy known under the name of BITNET; your only chance is to find a case where it screws up their UUCP lists, suggest that they should NOT solve the problem by adding a 'Precedence: junk' tag to the mail header because this would cause serious LISTSERV mailing loops within BITNET, and wait a couple months :-) Eric
