AUTH PASSWORD and AUTH USERNAME and EXTERNAL IDENTITY

TCP/IP-channel-specific options: AUTH_PASSWORD (string), AUTH_USERNAME (string),  EXTERNAL_IDENTITY (string)
New in Messaging Server 7.0 update 1. In legacy configuration, these SMTP/LMTP client options provide the  credentials for SASL (SMTP AUTH) use by the SMTP/LMTP client; in Unified Configuration, these options are not used, having been replaced instead by the ,  , and   channel options.

SASL authentication will be attempted if either the   or   channel option is set, with  success required for message transmission if    is set.

The PLAIN and EXTERNAL SASL mechanisms are currently supported. The  and     TCP/IP-channel-specific options provide the credentials for the plain mechanism and  the   TCP/IP-channel-specific option provides the identity  string for SASL EXTERNAL. (  can be set to the empty  string to enable SASL EXTERNAL without an identity string.)

See the Base certmap options for general configuration of certificate mapping, as needed for EXTERNAL authentication via client certificates.
