EX19-ED-000128 The Exchange Sender Reputation filter must be enabled.

Information

By performing filtering at the perimeter, up to 90 percent of spam, malware, and other undesirable messages are eliminated from the message stream rather than admitting them into the mail server environment. Sender Reputation is anti-spam functionality that blocks 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. This setting enables the Sender Reputation function.

Solution

Open the Exchange Management Shell and enter the following command:

Set-SenderReputationConfig -Enabled $true
