Wrong email formatting when I received...

Hi,

I'm testing the editor. But when I send a email using the mail command of Php,
I receive the email but in the wrong format:

For example, I received this in my email client.

<h1>
Jose Melendez</h1>
<p>
Oferta #1 &nbsp; <span style="color:#0000ff;"><span style="font-size: 16px; ">Aprovechao&nbsp;<img alt="heart" height="20" src="http://alexnatural.com/ckeditor/plugins/smiley/images/heart.gif" title="heart" width="20" /></span></span></p>
<hr />
<p>
<strong><span style="background-color:#00ff00;">$420.00</span></strong></p>
<p>
&nbsp;</p>
<p>
Visit us at: &nbsp;<a href="http://www.alexnatural.com" target="_blank">www.alexnatural.com</a></p>
<p>
...



I get the value here:
// get message to send
$message = $_POST["editor1"];

Then I use the php mail function to send the message.


Any idea?

Thanks,
