(off topic pedantry)

465 was at one time the de jure standard IANA registered port for smtps
(not "ssmtp") alongside the imaps and pop3s ports. The IETF foolishly
withdrew the registration for political reasons and it was subsequently
re-assigned to something else. Since the withdrawal there has been no
registered port for smtps, but smtps is required to support Outlook (not
just Outlook Express). Therefore operators have ignored the IETF's
mistake.

This is another example of IP "as she is spoke" being different from what
the standards say. Another good example is TCP congestion control which
wasn't described in an RFC until RFC 2001.

Also, MUAs typically use SSL to mean TLS-on-connect and TLS to mean
STARTTLS, and the setting has no bearing on whether it uses version
3.0 and earlier or 3.1 and later of the protocol.
