TLS is not required for SASL, but is highly recommended to protect plain-text credentials from eavesdroppers. At any rate, don't configure TBird to submit mail to postfix via TLS/SSL unless you enable TLS/SSL in postfix. For easy setup of postfix TLS, see http://www.postfix.org/TLS_README.html#quick-start (but be sure to read the whole document, not just the quick-start section). -- Noel Jones
