Configuring Content Filtering

Before configuring Content Filtering in the message processing rule, make sure that Content Filtering is enabled in general protection settings.

To configure Content Filtering settings in the message processing rule:

  1. In the application web interface window, select the Rules section.
  2. In the rule table, select the rule for which you want to configure Content Filtering.

    This opens the View rule window.

  3. Click Edit.

    Rule settings become editable.

  4. In the left pane, select the Content Filtering section.
  5. Use the toggle switch to the right of the section title to enable or disable Content Filtering of messages that match rule criteria.

    By default, Content Filtering of messages is disabled.

  6. If at the previous step, you have enabled Content Filtering, configure the following filtering criteria:
    • By message size
    • By attachment format
    • By attachment name.
  7. If you want to scan for forbidden formats or names of files within compound objects (including archives), select the Scan compound objects check box.

    If you enable scanning compound objects, the Scan file formats and names in archive check box is selected automatically because archives are a subset of compound objects.

  8. If at the previous step, you did not enable scanning compound objects and want to scan for forbidden formats or filenames only in archives, select the Scan file formats and names in archive check box.
  9. Click Save.

Content Filtering is configured. The specified settings are applied to messages that match the rule criteria.

To make sure the configured settings are applied during the operation of Kaspersky Secure Mail Gateway, enable Content Filtering for the rule and enable the configured rule.
