The Postfix SMTP client sends no realm information. If the server
expects a login name in the form "u...@domain" then it is up to you
to configure this as the username in smtp_sasl_password_maps.
As of 20070614, the Postfix SMTP client by default sends no authzid
(authoriZation ID), only the authcid (authentiCation ID) + the
authcid's password. This is configurable with send_cyrus_sasl_authzid
(default: no).
Happy holidays.
