We did the smtp config from GUI and used the test button - we usue mgmt port for this config - it keeps using tls 1.0 but our mimecast server supports tls 1.2, how can i make the mgmt port use tls 1.0 for this connection?
The client hello shows it using tls 1.0.. i cant find any option to change this!
Hi! Have you checked the client cipherlist with tcpdump? The client suggests ciphers and the server chooses according to it's cipher priority config. Sadly it would seem like sSMTP 2.64 is used and a quick Google says it only supports TLS 1.0.
