Content filter: Overview 

A second function of Content Management is content filtering, which performs a more sophisticated analysis of the messages. Like the spam filter, the content filter evaluates messages on the basis of user-defined rules. The content filter, however, examines the message text itself for the occurrence matching words or phrases that have been defined by the user. These rule sets, or policies, can be created to check for the use of inappropriate language, guard against the loss of proprietary information, scan for resumes, etc.

The content filter supports scanning double-byte messages, such as messages in Chinese and Japanese.
