Does MSN Messenger support SSL connectivity?

Hello,

Does anyone know if any version of MSN Messenger supports SSL connectivity
for relatively private / secure communications? If so, which version(s)
support it and how does one turn it on?

If not, does anyone know of an instant messaging solution that supports MSN
contacts and SSL communications?

I could not find information about such on Microsoft's websites. I do know
that in many troubleshooting forums, SSL 2.0 and 3.0 should be turned on in
IE's preferences; however, I did not know if this implicitly means that MSN
Messenger itself also supports SSL.

Thank you in advance,
Joe
