Use the Action tab on the sender reputation properties to set the threshold for sender blocking based on sender reputation level (SRL). The SRL is a number between 0 and 9 that predicts the probability that a sender is a spammer or an otherwise malicious user.

The SRL block threshold defines the SRL value that must be exceeded for sender reputation to block a sender. By default, the SRL value is set at 7. Before you adjust the SRL value, you should monitor its effectiveness at the default level.

After you have monitored its effectiveness, you may find that you can adjust the SRL value to meet the needs of your organization. If you set other anti-spam agents aggressively, you may be able to set a higher SRL block threshold for sender reputation than you would if the other anti-spam agents were not set aggressively.

For more information about how to adjust anti-spam configurations so that they work together to reduce spam, see Anti-Spam and Antivirus Functionality.
