This topic explains how to use the Exchange Management Console or the Exchange Management Shell to enable sender reputation. Sender reputation is anti-spam functionality that is enabled on computers that have the Microsoft Exchange Server 2007 Edge Transport server role installed to block messages according to many 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 is not installed on the Hub Transport server. For more information about installing and running sender reputation on the Hub Transport server, see How to Enable Anti-Spam Functionality on a Hub Transport Server.

Before You Begin

To perform the following procedures on a computer that has the Edge Transport server role installed, you must log on by using an account that is a member of the local Administrators group on that computer.

Also, before you perform these procedures, confirm the following:

You have reviewed 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.
You have read Configuring Sender Reputation.

Enabling or Disabling Sender Reputation

By default, sender reputation processing is enabled on the Edge Transport server for inbound messages that come from the Internet but are not 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.
