It is not "SSL *or* TLS", it is "SSL/TLS", the two are the same, just different revision levels of a single protocol: SSL 2 - Obsolete Netscape SSL protocol SSL 3 - Version 3.0 of the SSL protocol TLS 1.0 - Version 3.1 of the SSL protocol an IETF standard TLS 1.1 - Version 3.2 of the SSL protocol an IETF standard TLS 1.2 - Version 3.3 of the SSL protocol an IETF standard You can safely disable SSLv2. Now there is also a separate question of how SSL/TLS is used, STARTTLS versus wrapper-mode. See a recent post by Noel Jones in the list archive. -- Viktor. P.S.
