TLS 1.2 on SMTP ports

Post by webshaun » Thu Aug 30, 2018 11:07 pm

When will TLS 1.2 be supported? According to my tests, TLS 1.0 is disabled in the registry but when I run tests from I'm seeing TLS 1.0. Please advise.

TLS 1.2 is supported. If TLS 1.0 is advertised then you need to ensure that TLS 1.2 is enabled for your Windows platform: ... elTR_TLS12
