Enable or Disable Sender Reputation

 

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

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.

Looking for other management tasks related to anti-spam and antivirus features? Check out Managing Anti-Spam and Antivirus Features.

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.

Prerequisites

• Review Understanding Anti-Spam and Antivirus Functionality to understand the general strategy for configuring all anti-spam agents so that they work together efficiently for your organization.

• Read Understanding Sender Reputation.
