Are you trying to block any external access---or just mail?

I think what you need is a firewall--I have no personal experience, but there should be reams of info out there. Note that--once you have external access--you can always post mail using web sites. Give a clear description of exactly what priveleges you want your users to have.

use a firewall to block port 25 outbound from the mailserver.
the initial response was correct..
