It's important to distinguish SSL and TLS. With SSL you use port 465
and start ssl before any data is transmitted. With TLS you use the
default SMTP-port 25 and initiate SSL later as shown above.

The monit socket sets SSL_VERSION_AUTO so SSL version or TLS should be transparent and automatically setup by OpenSSL during the handshake. So no need to distinguish between ssl|tls, at least that is the theory.

Ah I was too fast when replying and did not see that STARTTLS first speak plain text before negotiating SSL. Ok, in that case distinguish between ssl|tls _is_ important.
