Enable or Disable Recipient Filtering
Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2
When recipient filtering functionality is enabled, it filters all messages that come through all Receive connectors on that computer. By default, recipient filtering is enabled on the computer that has the Edge Transport server role installed for inbound messages that come from the Internet but aren't authenticated. These messages are handled as external messages.
Note
The Recipient Filter agent is the underlying agent for recipient filtering functionality. It's important to understand that when you perform the following procedures, recipient filtering functionality is enabled or disabled, but the underlying Recipient Filter agent is still enabled. To disable the underlying Recipient Filter agent, run the Disable-TransportAgent cmdlet.
