UPAS(8) 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 determined 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 understandable to upas. Upas's rewriting rules (mail(7)) contain ed(1) style substi- tutions that allow addresses to be transformed into the com- mands 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 forwarding 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.
