Ah, then it's not mail distribution but an attempt at distributing a file
to some user with a domain-style address. LISTSERV then makes a mail
envelope around the file, and if the user doesn't exist it gets a
nastygram back. You don't want to put the user's address there because
one of the purposes of DISTRIBUTE is *not* to get zillions of 'Sent file'
messages; I'm not sure the users would like to trade them for '*Mail sent
to' messages :-)
