The intersection of (SASL mechanisms in the Postfix SMTP client) and (SASL mechanisms in the remote SMTP server) is empty. Look at: 1) The supported mechanisms in the Postfix SMTP client. These are controlled with smtp_sasl_tls_security_options and smtp_sasl_mechanism_filter, and also depend on what Cyrus SASL modules you have installed. 2) The supported mechanisms in the remote SMTP server. These are found with with "openssl s_client -starttls smtp host:25". This must have been covered a dozen times by now. Wietse
