Quoting Paul Wilkins <paulwilkins...@gmail.com>:
One thing you might check is the cipher set you're using. I can connect to https://tpg.com.au with TLS1.2 just fine. TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, 256 bit keys, TLS1.2 Output of following can usually highlight problems: openssl s_client -connect mx1.tpgi.com.au:465 or curl -v smtps://mx1.tpgi.com.au:465
The issue with TLS 1.2 is that it's susceptible to a downgrade attack, therefore bringing it down to 1.1/1.0/SSL3.
