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
