I don't have any experience setting up an SMTP server to support TLS or
SSL, but the client-side setup is quite easy. For roaming access with a
laptop computer, authenticated SMTP on an alternate port is definitely
the preferred solution, if you have access to an SMTP server that
supports it. (Fortunately for me, the U of M's main mail server does,
so I didn't need to set it up myself.)
The client setup is described here for about 6 different common mail
clients:
