Well, you can do it as postmaster (or at  least I can  as postmaster on our
LISTSERV),  and also the  user can do it by   telneting to port  25 on your
system and forging   some mail from  the  old  address.  Even  if  LISTSERV
generates a confirmation  ("OK") request,  this will work  as  long as mail
sent to the old address still gets to the new address -- the user will just
have to forge the OK as well, inserting the correct cookie.
