<h1>HTML Feature Filtering</h1>

<p>The HTML Feature filter searches the body of messages for HTML tags. 
 Spammers often use HTML tags to hide text from spam filters. Using this 
 page, you can select which HTML features you want to be considered indicators 
 of spam. You also specify how many of the selected features must be found 
 before an e-mail is identified as spam, and what action to take on such 
 messages.</p>

<h2>To Setup HTML Feature Filtering, do the following:</h2>

<ol class=whs1
	style="list-style: decimal;"
	type=1>
	
	<li class=kadov-p-CTopic-Text-Numbered>

	</li>
	
	<li class=kadov-p-CTopic-Text-Numbered><p class=Topic-Text-Numbered>In 
 the list box, select which HTML features you want to search messages for,
