UUCP-style addressing
                    Remote recipients are specified by  prefixing
                    the  recipient  name  with  the remote system
                    name  and  an  exclamation  point,  such   as
                    sysa!user.  If  csh(1)  is the default shell,
                    sysa\!user should be used.  A series of  sys-
                    tem names separated by exclamation points can
                    be  used  to  direct  a  letter  through   an
                    extended network (such as sysa!sysb!sysc!user
                    or sysa\!sysb\!sysc\!user ).
Domain-style addressing
                    Remote recipients are specified by  appending
                    an  ` @' and domain (and possibly sub-domain)
                    information to the recipient  name  (such  as
                    user@sf.att.com).  (The local system adminis-
                    trator should be  consulted  for  details  on
                    which addressing conventions are available on
                    the local system.)
