Yes. This gives you the option that, subject to setting various configuration flags and supplying SSL keys and certs, in any SMTP dialogue, as a receiver postfix will offer 'STARTTLS' as an available command, and as a sender it will invoke STARTTLS when the other side offers it. So all your e-mail should be encrypted over the wire. I'm not entirely sure why this is even considered optional in this day and age...
