Dear sirs,
     I have got a problem in sending a mail to list in our side. We
created a test list under LISTSERV in our node. When someone in the
list sent a mail to the list. Several UNNAMED MAILs were sent to
the postmaster by error. Obviously, the mail was not distributed to
the list members. Is anything wrong here? The rejected mail was as
following:
