postmaster
     
        The {electronic mail} contact and maintenance person at a site
        connected to the {Internet} or {UUCPNET}.  Often, but not
        always, the same as the {admin}.  The Internet standard for
        electronic mail ({RFC} 822) requires each machine to have a
        "postmaster" address; usually it is aliased to this person.
        See also {webmaster}.
