Cisco Cisco Email Security Appliance C370D Guia Do Utilizador

Multiple conditions may defined for each filter. When multiple conditions are 
defined, you can choose whether the conditions are tied together as a logical OR 
(“Any of the following conditions...”) or a logical AND (“All of the following 
conditions”). 

Specifying conditions in content filters is optional. If no 
conditions are specified, a 

true

 rule is implied. The 

true

 

rule matches all messages, and the actions are always 
performed. 

Contains text: Does the message body contain text or an 
attachment that matches a specific pattern? 

Contains smart identifier: Does content in the message 
body or attachment match a smart identifier?

Contains term in content dictionary: Does the message 
body contain any of the regular expressions or terms in the 
content dictionary named <dictionary name>?

For this option to be enabled, the dictionary must already 
have been created. See 

.

Number of matches required. Specify the number of 
matches required for the rule to evaluate to true. You can 
specify this threshold for text, smart identifiers, or content 
dictionary terms.

This includes delivery-status parts and associated 
attachments.
