Using the Block/Accept Filters
Filtering by Body Contents
The BLOCK/ACCEPT-->Body Filtering page lets you filter messages based on the contents of a
message’s body.
The following table describes the parameters on this page. Click Save Changes after making any
changes to this page.
Note the following about content filtering:
■ You can enter multiple lines for each filter, but each line should contain one regular expression or
word. Each line is applied independently.
■ HTML comments and tags imbedded between characters in the HTML source are filtered out so
content filtering applies to the actual words as they appear when viewed in a web browser.

The BLOCK/ACCEPT-->Header Filtering page lets you filter messages based on the contents of a
message’s header content.
