UPAS(8)                     System Manager's Manual                    UPAS(8)



NAME
       upas - address driven mailer

SYNOPSIS
       mail person ...
       rmail -N network person ...
       cmail -N network person ...

DESCRIPTION
       Upas  is  a mail delivery system that disposes of messages in a way de‐
       termined by the destination address and a set of rewriting  rules.   It
       can  be used to recognize many address formats and route remote mail to
       different network mail interfaces.

       mail   is used by a user to send or read mail.  See mail(1).

       rmail  is used to inject mail coming from other machines into the  mail
              system.  No message conversion is performed.

       cmail  is  used to inject mail formatted according to ARPA RFC 822 into
              the mail system.  The mail is converted into a form  understand‐
              able to upas.

       Upas's rewriting rules (mail(7)) contain ed(1) style substitutions that
       allow addresses to be transformed into the commands used to inject mail
       to the networks.

       The  -N  option  causes the `network' indicates the name of the network
       from which the message is coming.  This network name  is  prepended  to
       the return address.

       Each  message  submitted using rmail or cmail is checked against a for‐
       warding list.  Unless the name of all machines in the  source  path  or
       all  machines  in  the destination path are in the forwarding list, the
       message is refused.
