Configure Content Filtering

This topic explains how to use the Exchange Management Console or the Exchange Management Shell to configure the Content Filter agent in Microsoft Exchange Server 2007. This topic also provides an introduction to configuration of the Content Filter agent.

To configure the Content Filter agent, you must follow these steps:

  1. Enable the Content Filter agent.
  2. Specify a spam quarantine mailbox.
  3. Enable and configure the spam confidence level (SCL) thresholds and SCL threshold actions. These actions include deleting messages, rejecting messages, or quarantining messages.
  4. Enable or disable puzzle validation.
  5. Specify recipient and sender exceptions.
  6. Configure Allow phrases and Block phrases.
  7. Set the rejection response.

Important

Configuration changes that you make to the Content Filter agent by using the Exchange Management Console or the Exchange Management Shell are made only to the local computer that has the Edge Transport server role installed. If you have multiple instances of the Edge Transport server role running in your organization, you must configure the Content Filter agent on each computer.

Note

Safelist aggregation is performed by the Content Filter agent. Safelist aggregation is likely the most effective way to reduce false positives. As its name suggests, this functionality collects data from the anti-spam safe lists that Microsoft Office Outlook and Outlook Web Access users configure and makes this data available to the anti-spam agents on the Edge Transport server in Exchange Server 2007. Although the Content Filter agent acts on the safelist aggregation configuration, you do not administer or configure safelist aggregation directly through the Content Filter agent. However, the Content Filter agent must be enabled for safelist aggregation to function.
