Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

The 

reputation

 rule checks the SenderBase Reputation Score against another 

value. All the comparison operators are allowed, such as 

>

, 

==

, 

<=,

 and so forth. 

If the message does not have a SenderBase Reputation Score at all (because one 
was never checked for it, or because the system failed to get a response from the 
SenderBase Reputation Service query server), any comparison against a 
reputation fails (the number will not be greater than, less than, equal to, or not 
equal to any value). You can check for a SBRS score of “none” using the 

no-reputation

 rule described below. The following example adjusts the 

“Subject:” line of a message to be prefixed by “

*** BadRep ***

” if the reputation 

score returned from the SenderBase Reputation Service is below a threshold of 
-7.5..

 For more information, see “Reputation Filtering” and “SenderBase Reputation 
Score (SBRS)” in the Cisco IronPort AsyncOS for Email Configuration Guide.
