4.2.4 ESMTP Authentication Settings

The following options set authentication credentials for ESMTP authentication. You may use this option, for example, if your MTA requires such an authentication, but your MUA does not support it.

Option: esmtp-allowed-mech mech-list

Defines the list of allowed authentication mechanisms. Mech-list is a list of valid authentication mechanism names separated by whitespace.

Anubis selects the authentication method using following algorithm: The MTA presents the list of authentication methods it supports. For each element in mech-list, Anubis tests whether it is available in the list presented by MTA. If found, this method is selected. For example, suppose that the MTA supports following mechanisms:

PLAIN LOGIN CRAM-MD5 ANONYMOUS

and you have following statement in your configuration file

esmtp-allowed-mech DIGEST-MD5 CRAM-MD5 LOGIN

In this case Anubis will select CRAM-MD5.

Option: esmtp-require-encryption mech-list

This statement declares the list of mechanisms that can be used only over a TLS encrypted channel. By default Anubis uses

esmtp-require-encryption LOGIN PLAIN

This prevents sending user password over an unencrypted connection.

Option: esmtp-auth-id authentication-id

Sets authentication ID (user name).

Option: esmtp-authz-id authorization-id

Sets authorization ID (user name).

Option: esmtp-password password

Sets password to be used in authentication.

Option: esmtp-auth username:password

This option sets both authentication and authorization IDs and the password. It is equivalent to

esmtp-auth-id username esmtp-authz-id username esmtp-password password

The following options specify authentication credentials for GSSAPI, DIGEST-MD5 and KERBEROS_V5 authentication mechanisms:

Option: esmtp-service service-name

Sets the name of GSSAPI service.

Option: esmtp-hostname hostname

Sets hostname of the machine.

Option: esmtp-generic-service servise-name

Sets generic service name.

Option: esmtp-passcode passcode

Sets passcode.

Option: esmtp-realm realm-name

Sets GSSAPI realm.

Following option is useful with ANONYMOUS authentication mechanism:

Option: esmtp-anonymous-token token

Sets the token to be used with ANONYMOUS authentication mechanism
