Recently my server received a subscription request from a user at
CUNYVM.  For reasons unrelated to this query, the subscription request
bounced.  What I'm trying to understand is:  how did a real mail origin
of CUNYVM become "CUNYVM.HARVARD.EDU"????
 
Edited excerpt from LISTSERV console log:
 
29 Mar 1993 18:15:58 Processing file 8584 from MAILER@HARVARDA
29 Mar 1993 18:15:58 From [log in to unmask]: SUBSCRIBE LLLLLL-L  ...
29 Mar 1993 18:15:58 To   [log in to unmask]: Sorry,  list  LLLLLL-L  ...
03/27/93  23:23  by (...)
29 Mar 1993 18:15:59 Sent information mail to [log in to unmask]
 
Edited excerpt of LISTSERV's reply to user (which was in turn bounced
back to me):
