ADDRESS(1)                       UNIX System V                       ADDRESS(1)


NAME
      address - display the path generated by uumail for an RFC822/RFC976-
      format address.

SYNOPSIS
      address rfc-address [ ... ]

DESCRIPTION
      This program allows you to check the UUCP mail routing path that will be
      generated by the UUCP mailer uumail if you specify an RFC822/RFC976-
      format address rfc-address in the To:'' field of the mail header.  For
      each RFC-style address on the command line, address echoes the address to
      the standard output, followed by a colon, followed by the UUCP address
      that will be used to send the message to that address.


ADDRESS FORMAT
      Briefly, the RFC822/RFC976-format address is of the form

            <localaddress>@<hostname>.<domain>

      where <hostname> is the name of the system you are sending the message
      to, <domain> is a modifier for <hostname> identifying the network in
      which the address is to be interpreted (EDU, COM, GOV, ORG, NET, etc.);
      and <localaddress> is an address string to be interpreted on the host
      machine.

      On our system, the presently valid <domains>s are EDU, COM, GOV, ORG,
      NET, UUCP, and ARPA.  Omitting the <domain> causes the network to default
      to UUCP.  The <hostname> should be the name of a remote machine to which
      the message is directed; see /usr/lib/uucp/paths for a list of all known
      UUCP hostnames.  It is not necessary to specify a UUCP pathname when
      using this format; the pathname is automatically determined for you and
      substituted into the address before mailing.  The selected pathname is
      determined using the pathalias database, and is supposed to be optimal,
      taking into consideration information provided by each site about how
      often they send mail out, etc.


EXAMPLES
      joe
           The message is sent to the user joe'' on the local system.

      joe@ucbvax
           The message is sent to joe on the UUCP system named ucbvax''; this
           address is automatically translated to a proper (and ostensibly
           optimal) UUCP path.

      joe@ucbvax.UUCP
           Same as joe@ucbvax

ADDRESS(1)                       UNIX System V                       ADDRESS(1)


      joe@ucbvax.ARPA
           The message is addressed to joe at ucbvax, using the ARPA network.
           The message will be routed to the ARPAnet via a UUCP-ARPAnet
           gateway.

      ucbvax!multics.mit.edu!joe
           The message is sent to ucbvax, who then uses the address
           joe@multics.mit.edu to send the message on to multics.mit.edu via
           the ARPAnet.  Since ucbvax is on the arpanet, this address will work
           correctly (as long as there is someone named joe on the MIT multics
           machine).

      ucbvax!multics.mit.edu!vanderbilt.mailnet!joe
           The message is sent via UUCP to ucbvax, who then sends the message
           to multics.mit.edu via the arpanet; multics.mit.edu then sends the
           message to joe@vanderbilt via MAILNET.  Since the above machines
           each have access to the networks named in the address, this address
           will work correctly.
