This combination of ancient OpenSSL and bleeding edge Postfix is
suboptimal from a TLS perspective. Most of the newer features
in Postfix TLS support require OpenSSL 1.0.0 or newer.
Real mail clients do not generally enable just TLSv1.2, there are
still MTAs out there that support only SSLv3, not even TLSv1.
