At this  point the  GLX doesn't  handle this, mostly  because you  want a
different behaviour  for xxx-request@CMUVM and  for [log in to unmask]
If the  mail is explicitly  directed to your host  but the list  does not
exist,  it could  be because  of  a spelling  problem or  because it  was
deleted and the postmaster should probably get  a copy. If it was sent to
the generic LISTSERV node it should be forwarded.
