Other settings related to SBRS score thresholds, and Mail Flow Policy settings, are described in 

If your Cisco appliance is set to receive mail from a local MX/MTA, identify upstream hosts that 
may mask the sender's IP address. See 

 for more information. 

Understand Sender Base Reputation Scores. See

Unless you regularly receive a large portion of spam, or you have set up “dummy” accounts to 
specifically receive spam for your organization, it may be difficult to immediately test the SBRS policies 
you have implemented. However, if you add entries for reputation filtering with SenderBase Reputation 
Scores into a listener’s HAT as indicated in 

, you will notice that a smaller percentage of 

inbound mail will be “unclassified.”

Test the policies using the 

trace

 command with an arbitrary SBRS. See 

. The 

trace

 command is available in the CLI as well as the GUI.
