Sensitive Content FilterBefore CodeTwo Exchange Rules PRO processes any messages and performs any actions, it checks the defined conditions. If the message or messages meet the condition then it is processed. If not, the rule will not be applied and no action will be taken. Apart from the condition it is possible to define exceptions. If the defined exception is met then the rule will not be applied. One of the available exceptions is the sensitive content filter. It is designed to search for the sensitive information in the messages. If you apply this exception, CodeTwo Exchange Rules PRO will search and detect such information in the body of the message. After such content is found, the rule won't be applied.
In order to activate this option on the Exceptions tab, in the List of Exceptions click Add, and then select Sensitive content filter (Fig.1.).

Sensitive content filter will be added to the list of exceptions in the middle pane, while the right pane will show the exceptions properties (Fig.2.).

Predefined dictionaries will be displayed in the properties of the Sensitive content filter. You need to choose the proper dictionary by checking the box next to its name, for example Credit Cards. You need to set up minimal score for each dictionary. When the number of defined phrases will reach the score number CodeTwo Exchange Rules PRO will skip the message and will not process the rule. If you want to check the score number for the group of phrases you need to click the Open dictionary button. You will see a new window with the predefined dictionaries on the left. If you select a dictionary, you can view, edit or add new phrases on the right pane. You may also change the weight number for each individual phrase (Fig.3.). You can read more about the specific options of the dictionary in the Dictionaries chapter.

After you select a dictionary and make some changes, you need to save your settings by clicking the OK button. The exception will be saved and CodeTwo Exchange Rules PRO will not perform any actions on the message that contains sensitive information.
