Cisco Cisco Email Security Appliance C160 Mode D'Emploi

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 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. 

Email Security Manager tables match incoming or outgoing messages for specific 
groups of users (Envelope Recipients, Envelope Sender, From: header, or 
Reply-To: header) and map them to specific settings for the following features: 

Anti-Spam Scanning — These settings are the same settings as per-listener 
settings in previous releases of AsyncOS. See 

 for 

more information. 

Anti-Virus Scanning — These settings are the same settings as per-listener 
settings in previous releases of AsyncOS. See 

 for 

more information. 

Content Filters — See

Virus Outbreak Filters 

IronPort’s Virus Outbreak Filters feature is a predictive security service that 
provides a “first line of defense” against new virus outbreaks by quarantining 
suspicious messages until traditional anti-virus security services can be 
updated with a new virus signature file. You can enable or disable Virus 
Outbreak filters for given recipients, and also define the file types that will 
bypass the Virus Outbreak Filters feature in Email Security Manager. See 

 for more information.

Data Loss Prevention — See 

 for more 

information.

and Content Filters settings.
