This should render the ports inactive and unable to accept connections on them. You can also do the same on a per server basis under the Server, Protocols, properties for each protocol. This will cover the Exchange protocols only though. I really think that if you are wanting to filter that many ports, you should look at a firewall. Heck, even if it is a software firewall to start with. It would be better than nothing.

Are you behind a FW?
