Postfix TLS Support, Feb 8 2008
With Postfix < 2.3, the obsolete smtp_tls_cipherlist parameter is also applied for opportunistic TLS sessions, and should be used with care, or not at all. Setting cipherlist restrictions that are incompatible with a remote SMTP server render that server unreachable, TLS handshakes are always attempted and always fail.
