Hi I have heard of the vulnerability that exists in SSL 3.0 and TLS 1.0 that could allow information disclosure if an attacker intercepts encrypted traffic served from an affected system. TLS 1.1, TLS 1.2, and all cipher suites that do not use CBC mode are not affected.
How do i use specific versions of tls in postfix . thanks !! -- Regards Agnello D'souza
