To use smart identifiers in a filter, enter the following keywords in a filter rule that scans body or 
attachment content:

When you use a smart identifier in a filter rule, enter the smart-identifier keyword in quotes within a filter 
rule that scans the body or attachment file, as in the example below:

You can also use smart identifiers in content filters and as a part of content dictionaries.

You cannot combine a smart identifier key word with a normal regular expression or another key word. 
For example the pattern 

*credit|*ssn 

would not be valid. 

To minimize on false positives using the *SSN smart identifier, it may be helpful to use the *ssn smart 
identifier along with other filter criteria. One example filter that can be used is the “only-body-contains” 
filter condition. This will only evaluate the expression to be true if the search string is present in all of 
the message body mime parts. For example, you could create the following filter:

SSN-nohtml: if only-body-contains(“*ssn”) { duplicate-quarantine(“Policy”);}

*credit

Credit card number

Identifies 14-, 15-, and 16- digit credit 
card numbers. 

NOTE: The smart identifier does not 
identify enRoute or JCB cards.

*aba

ABA routing number

Identifies ABA routing numbers.

*ssn

Social security number

Identifies U.S. social security 
numbers. The *ssn smart identifier 
identifies social security numbers with 
dashes, periods and spaces.

*cusip

CUSIP number

Identifies CUSIP numbers.

ID_Credit_Cards:

if(body-contains("*credit")){

notify("legaldept@example.com");

}
