Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

 

Anti-spam processes scan email for incoming (and outgoing) mail based on the mail policies that you 
configure. 

One or more scanning engines scan messages through their filtering modules. 

Scanning engines assign a score to each message. The higher the score, the greater the likelihood 
that the message is spam. 

Based on the score, each message is categorized as one of the following: 

Not spam 

Unwanted marketing email from a legitimate source 

Suspected spam 

Positively-identified spam 

An action is taken based on the result. 

Actions taken on messages positively identified as spam, suspected to be spam, or identified as 
unwanted marketing messages are not mutually exclusive; you can combine some or all of them 
differently within different incoming or outgoing policies for different processing needs for groups
