Content Control

Content Barring examines the data being carried by some of Mailtraq's services and can be used to filter out unwanted or unwelcome data. The filters can be applied selectively to Users, to their IP Addresses, or to both. Entire or partial online resources may also be filtered out by specifying URL in a combination of blacklists and whitelists.

Breaches of Content Barring policy can be reported in real time by email to a local or remote address. Content Barring is aimed mainly at data being processed by the HTTP Service but can also be applied to Incoming Mail.

The Content Tab, which appears on the Content Barriers dialog, provides access to a phrase file, the contents of which are compared by Mailtraq against the data being scanned by the content barrier. Web pages which match entries in the phrase file are added to the Ban Cache to prevent further access.

Phrase File
The default phrase file is \database\configuration\cbar\default.txt which contains a predefined set of encoded phrases which provide a suitable base for monitoring web content for students.

A new phrase file can be created by entering a filename and extension into the text box, for example "sample.txt" (without the quotes), clicking on the  button and responding "Yes" when asked "Do you want to create a new file?" An existing phrase file can be specified by clicking on the  button and selecting a file in the cbar folder from the standard Windows file dialog.
