Chapter 10: E-mail Filtering

Overview

The key logger created in Chapter 8 can be enhanced to log from only e-mail applications, and the network filter created in Chapter 7 can be enhanced to sift through low-level protocols and piece together e-mail; but in a business environment where Microsoft Exchange Server or Lotus Domino Server is being used, there is a better way. These corporate e-mail solutions provide the capability to extend client functionality through the use of specially crafted Dynamic Link Libraries. All that is needed to filter e-mail in this environment is an understanding of the extension interface built into the target e-mail system.

This chapter includes the following:

• Microsoft Outlook e-mail filtering

• Installing an Outlook client filter

• Testing the Outlook client extension

• Lotus Notes e-mail filtering

• Installing a Lotus Notes client filter

• Testing the Lotus Notes client extension
