(http://support.microsoft.com/kb/256986/EN-US/ )Description of the Microsoft Windows Registry
In Microsoft Exchange 2000 Server or Exchange Server 2003, after you configure the Delivery Restrictions option on a connector, the restriction settings may not be applied.
The restriction checking functionality is controlled by a registry key that is set on the Exchange bridgehead server that is the source for the connector that is being checked. If you need to apply a restriction to a connector which restricts who is able to send data to the designated link, you must manually add the restriction checking registry value.
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
To enable restriction checking:
When you enable the Delivery Restrictions option, the computers performance may be affected. When you set the registry value, every message for every destination is checked.
