Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

For example, for “SUSPECTLIST,” enter a range from -4.0 to 0. Refer to 

 for the 

syntax. 

Click Submit. 

Repeat steps 2-5 for each group in the listener’s HAT. For example, define the 
values for conservative approach. You can configure the values shown in 

 for a moderate or aggressive approach as well.

Remember that order matters when defining sender groups in a listener’s 
HAT. (The HAT is read from top to bottom for each host that attempts to 
connect to the listener. If a rule matches a connecting host, the action is 
taken for that connection immediately.) Cisco recommends maintaining 
the default order of the predefined sender groups in a listener’s HAT — 
that is, RELAYLIST (C10/100 customers only), followed by 
WHITELIST, BLACKLIST, SUSPECTLIST, and UNKNOWNLIST.

Click the Commit Changes button, add an optional comment if necessary, and 
then click Commit Changes to finish implementing reputation filtering in a 
listener’s HAT. 

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.”
