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.

Checking this box will cause AsyncOS to consider the case of the word when 
matching. For example, the words “codename” would match a dictionary entry of 
“codename”, but the word “CodeName” would not match.

Checking this box will cause words to match only if they match the whole entry. 
For example, the word “codename” would match a dictionary entry of 
“codename,” while “code” and “codenam” would not.
