Messenger uses RFC2487 "STARTTLS" for SSL over SMTP.  It basically
means that a supporting SMTP server sends a "250-STARTTLS", and
the supporting SMTP client sends a "STARTTLS", and then all further
traffic is negotiated securely.

Look at stunnel's "-n smtp" or sendmail-tls (find it on freshmeat),
and you might have more luck than I've had.
