5.2.1 Basic Settings

Option: bind [host:]port

Specify the TCP port on which GNU Anubis listens for connections. The default host value is `INADDR_ANY', which means that anyone can connect to GNU Anubis. The default port number is 24 (private mail system). This option is available only in the system configuration file. If you would like, for instance, to bind GNU Anubis to port 25 (SMTP) and limit its clients only to those from `localhost', then set the following in your system configuration file:

bind localhost:25

Option: remote-mta host[:port]

Specify a remote SMTP host name or IP address, which GNU Anubis will connect and forward mail to (after a processing). The default port number is 25. This option is available in both configuration files.

Option: local-mta file-name [args]

Execute a local SMTP server, which works on standard input and output (inetd-type program). This option excludes the `remote-mta' keyword (or `--remote-mta' command line option). For example:

local-mta /usr/sbin/sendmail -bs

Option: mode mode-name

Selects Anubis operation mode. Allowed values for mode-name are:

transparent

auth

See section 4. Authentication, for the detailed discussion of GNU Anubis operation modes.
