SUMMARY
Conceptually, the SMTP connector in Exchange 2000 Server and Exchange Server 2003, while often compared to the Internet Mail Service in Microsoft Exchange Server 5.5, is not the same when it comes to the issue of transfer mode control.

The SMTP connector in Exchange 2000 and Exchange 2003 does not provide any control of the Inbound transfer mode. In other words, inbound delivery is dictated solely by which server is designated as the Mail Exchanger in DNS. You cannot disable inbound delivery in the same way as in earlier versions of Exchange Server.

The Exchange 2000 and the Exchange 2003 SMTP connectors are responsible for the outbound transfer of messages for those domains that are specified on their properties Address Space tab.

To stop the outbound transfer of messages for a particular domain, delete the SMTP connector responsible for the domain. If the SMTP connector is responsible for more than one domain, the specific domain that is no longer required can be deleted from its Address Space entry. No manual intervention is required beyond this step because the routing information is automatically updated.



MORE INFORMATION
In earlier versions of Exchange, the setting for the Internet Mail Service provides control for both outbound and inbound message transfer.

To institute a change in the Address Space supported by the connector, you must make the change, and then manually run a recalculation for the routing information.

Furthermore, if you need to remove support for outbound transfer completely, the transfer mode must be set to reflect this, the Address Space entries must be deleted, a manual routing information update must be run, and the Internet Mail Service must be restarted.

With the redesign of the routing architecture in Exchange 2000 and later, one of the most important advantages is the dynamic update of routing information.
