Exchange 2010 - Prevent internal machines from using as a smart host
The developers in our environment continue to point various servers to our production email server to send test emails. All of these emails stay internal, so they aren't relaying. Is there anyway to prevent them from doing this?

The IP Address ranges on your Receive Connectors determine which systems can send mail to your Exchange Server. If you remove the internal network's IP range from the list of IP addresses on your Receive Connectors for port 25, it will prevent the Exchange Server from accepting mail from those clients. In order to send mail from an internal server to your exchange server, they'll have to ask for approval.

OK, so I currently have 3 connectors on my Hub/CAS server. They are as follows:
Client ServerName - Presume this is used by Outlook clients
Default ServerName - Presume this is the connector I need to modify
Relay Connector - This has all the machines that need relay access
My only concern is knowing what other machines are using this Default connector so I can make sure to list every IP needed. Do my other Exchange servers use this connector (2003 boxes and Edge)?
