anubis(1) an SMTP message submission daemon.


anubis [options]


GNU Anubis is an SMTP message submission daemon. It represents an intermediate layer between mail user agent (MUA) and mail transport agent (MTA), receiving messages from the MUA, applying to them a set of predefined changes and finally inserting modified messages into an MTA routing network. The set of changes applied to a message is configurable on a system-wide and per-user basis. The built-in configuration language used for defining sets of changes allows for considerable flexibility and is easily extensible.


The full documentation for GNU Anubis is maintained as a Texinfo manual. If the info and GNU Anubis programs are properly installed at your site, the command

info anubis

should give you access to the complete manual.
