Cisco Cisco Email Security Appliance X1070 Betriebsanweisung

Use the Incoming or Outgoing Mail Policies page to enable the new 
content filter for the default policy. 

Enable the content filter for all remaining policies.

The Bcc: and Quarantine actions available in Content Filters can help you 
determine the retention settings of quarantines you create. (See the 
“Quarantines” chapter in the Cisco IronPort AsyncOS for Email Daily 
Management Guide for more details.) You can create filters that would 
simulate mail flow into and out of your system quarantines so that messages 
are not released too quickly from the system (that is, the quarantine areas do 
not fill their allotted disk space too quickly). 

Because it uses the same settings as the 

scanconfig

 command, the “Entire 

Message” condition does not scan a message’s headers; choosing the “Entire 
Message” will scan only the message body and attachments. Use the 
“Subject” or “Header” conditions to search for specific header information.

Configuring users by LDAP query will only appear in the GUI if you have 
LDAP servers configured on the appliance (that is, you have configured the 
appliance to query specific LDAP servers with specific strings using the 

ldapconfig

 command). 

Some sections of the content filter rule builder will not appear in the GUI if 
the resource has not been preconfigured. For example, notification templates 
and message disclaimers will not appear as options if they have not been 
configured previously using the Text Resources page or the 

textconfig

 

command in the CLI. 

Content filters features will recognize, can contain, and/or scan for text in the 
following character encodings:
