Enable or Disable Sender Reputation

Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2

Topic Last Modified: 2012-07-23

Sender reputation is anti-spam functionality that's enabled on computers that have the Microsoft Exchange Server 2010 Edge Transport server role installed to block messages according to various characteristics of the sender. Sender reputation relies on persisted data about the sender to determine what action, if any, to take on an inbound message.

Note:
By default, sender reputation processing is enabled on the Edge Transport server for inbound messages that come from the Internet but aren't authenticated and are therefore handled as external messages. The Protocol Analysis agent is the underlying agent for sender reputation functionality. It's important to understand that when you perform the following procedures, sender reputation functionality is enabled or disabled, but the underlying Protocol Analysis agent is still enabled. To disable the underlying Protocol Analysis agent, run the Disable-TransportAgent cmdlet.
