Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

Because the iterative processing of each splinter message impacts performance, Cisco recommends 
configuring your content security rules on a managed exception basis. In other words, evaluate your 
organization’s needs and try to configure the feature so that the majority of messages will be handled by 
the default mail policy and the minority of messages will be handled by a few additional “exception” 
policies. In this manner, message splintering will be minimized and you are less likely to impact system 
performance from the processing of each splinter message in the work queue. 

Mail policies map different user groups to specific security settings, such as Anti-Spam or Anti-Virus. 

The default mail policies apply to messages that are not covered by any other mail policy. If no other 
policies are configured, the default policies apply to all messages. 

Understand how you can define the individual security services for the mail policy. See
