If your upstream relay host only supports PLAIN or LOGIN mechanisms (both of which send password in the clear), you have to remove noplaintext from smtp_sasl_security_options. Since noplaintext is present, postfix will refuse to use a mechanism that sends passwords in the clear. Smtp_sasl_security_options = noplaintext, noanonymous First check what auth mechanism postfix is configured to use - by default, you will see: You can fix this problem by tweaking the auth mechanisms that postfix is willing to use. (Authentication failed: cannot SASL authenticate to server.
