4.2.1 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.

For example, to bind GNU Anubis to port 25 (SMTP) and limit its clients only to those from ‘localhost’, set the following in your system configuration file:

bind localhost:25

Option: remote-mta host[:port]

Specify a host name or IP address of the remote SMTP. GNU Anubis will forward mails to that server. 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). For example:

local-mta /usr/sbin/sendmail -bs

The ‘CONTROL’ section must contain either local-mta or remote-mta, but not both.

Option: mode mode-name

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

proxy

transparent

auth

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

Option: read-entire-body yes-or-no

Normally, when processing a multi-part message with external filter (see section Using an External Processor), Anubis feeds only the first part to the filter. The rest of the message is copied verbatim. To alter this behavior so that your external program sees the entire message body, set read-entire-body yes in your control section.

Option: identd-keyfile filename

Sets the file name of the file that contains DES keys to use when decoding responses from the auth (ident) server. This file is used if auth server encrypts its responses. See section Auth Service, for details.

Option: incoming-mail-rule string

Declares the name of command section for incoming mail. Default is ‘INCOMING’. This option is available only for system configuration file. See section Using Anubis to Process Incoming Mail, for detailed description of incoming mail processing.

Option: outgoing-mail-rule string

Declares the name of command section for outgoing mail. Default is ‘RULE’. This option is available only for system configuration file.

Option: smtp-command-rule string

Declares the name of command section for rewriting SMTP commands. Default is ‘SMTP’. This option is available only for system configuration file. See section Modifying SMTP Commands.

Option: log-tag string

Tag syslog messages with string. Default is ‘anubis’.

Option: log-facility string

Use syslog facility string for logging. Valid argument values are: ‘user’, ‘daemon’, ‘auth’, ‘authpriv’, ‘mail’, ‘cron’, ‘local0’ through ‘local7’ (all names case-insensitive, optionally prefixed by ‘log_’), or a decimal facility number. Default is ‘mail’.

Option: local-domain string

Set local domain name. By default, the domain name is defined as the part of the local host name following the first dot.

Local domain name is used as SASL realm, unless overridden by ‘sasl-realm’ statement (see section sasl-realm).

Option: use-pam bool

Enable the Pluggable Authentication Module interface. If set to yes, anubis will uses PAM for accounting and session management (service name ‘anubis’).

The default is yes if PAM support is compiled in.
