PEAR mail

hi, i'm using Mail PEAR package and i want to send a mail to a recipient and to some other in Cc. So i try to add Cc in header but it failed and mail didn't been delivered to Cc. It was only delivered to adress specified in From field. I use that code : $hdrs = array(

                   "From"    => "adresse1@test.com",                                      "Cc" => "adresse2@test.com"
                   "Subject" => "Tests"
                   );
   $mime = new Mail_mime($crlf);      $mime->setHTMLBody(stripslashes($html));

$body = $mime->get(); $hdrs = $mime->headers($hdrs);

   $mail =& Mail::factory('smtp',$params);        $mail->send($recipients, $hdrs, $body);

Can someone say me how to use pear package to send a mail to an adress and to send it in copy to another one ? Marc SERRA.
