INTRODUCTION
This article describes how to filter e-mail messages that automatically load HTML images from a Web server in Sybari Antigen for Microsoft Exchange or in Microsoft Antigen 9.0.



MORE INFORMATION
To filter e-mail messages that automatically load HTML images from a Web server, use the following filters:
 * img _WITHIN[6]OF_ src=&quot;http&quot;
 * img _WITHIN[6]OF_ src='http'

These filters will identify instances of the text &quot;img&quot; that occur within six words of the following text:

src=&quot;http&quot;

If e-mail messages that contain HTML images are not filtered after you add these filters to the keyword list, you may want to examine the source code of the e-mail messages to see how these e-mail messages identify images. Then, you may create additional customized filters.

For more information about advanced keyword filters, see Chapter 14 of the Antigen User Guide.
