No, the other way: TLS is the successor of SSL. But many servers do
not support TLS but SSL. In general I would avoid to use any
encryption for the moment. You need a working STMP first. Encryption
is the second step. Try port 25. Modern servers also react on port 587
for normal (but authenticated) SMTP.

I still think this is TLS related.
