Here's one way this can happen:  user FOO@BAR (BAR = RSCS host name)
sends message "TELL LISTSERV AT USCVM SUB TRKNWS-L Foo Person".
 
In his MAILUSER XEDIT he has a statement
 
"SETMAIL LOCAL.DOMAIN BARROOM"
 
(BAR and BARROOM are the same machine but have separate BITNET entries)
so that when he creates mail using the Rice MUA, the header contains
 
From:  FOO@BARROOM
 
which LISTSERV can't find in the list.  Not hypothetical -- I've seen
it happen.  Here.
 
If the user is on a VMS machine, even stranger things can happen if
the mailer isn't set up correctly -- all sorts of "IN%" junk in the
address.
