Cisco Cisco Email Security Appliance C160 Guía Del Usuario

Type a name for the dictionary.

Specify whether to match whole words only by marking the checkbox next to Match Whole Words Only. 
See 

 for more information.

Specify whether to perform case-sensitive searches. See 

 for 

more information.

AysncOS preserves the Match Whole Words and Case Sensitive settings when they are saved in 
the configuration file. These settings are not preserved when importing and exporting 
dictionaries.

Optionally, add a smart-identifier to the dictionary. Smart identifiers are algorithms that search for 
patterns in data that correspond to common numeric patterns, such as social security numbers and ABA 
routing numbers. For more information about smart identifiers, see the “Using Message Filters to 
Enforce Email Policies” chapter in Cisco IronPort AsyncOS for Email Advanced Configuration Guide.

Enter new dictionary entries into the list of terms. For more information about the kinds of entries that 
are supported, see 

Specify a weight for the term. You can “weight” a dictionary term so that it is more likely than other 
terms to trigger a filter action. For more information about how this weight is used to determine filter 
actions, see “Threshold Scoring for Content Dictionaries” in the “Using Message Filters to Enforce 
Email Policies” chapter of the Cisco IronPort AsyncOS for Email Advanced Configuration Guide.

The Dictionaries page now lists the new dictionary, along with the terms included and the setting 
configured for the dictionary.

Content dictionary entries with the regular expression: “

.*

” at the beginning or end will cause the system 

to lock if a match for the “word” MIME part is found. Cisco Systems recommends you do not use “

.*

” 

at the beginning or end of a content dictionary entry.
