TLS and SMTP start by doing a cleartext negotiation and switching to an
encrypted session, whatever talks to qmail-smtpd will only use TLS if can

You must specify the servers you want to talk securely to, be default
qmail-remote sends mail in the clear as well.

Yes, ofcourse, RFC's are always informative. Read the information at the
top of the TLS patch as well.
