How to check if the remote SMTP server supports TLS 1.1

 First confirm if OpenSSL has been installed properly:

#which openssl

Then execute the command below:

#openssl s_client -starttls smtp -crlf -connect HOST:PORT -tls1_1

If the output shows TLS session ticket, the peer SMTP server supports.

Otherwise, it does not support.
