header html

Har følgende Klasse:

<?
class clsMail
{
  var $to;
  var $from;
  var $cc;
  var $bcc;
  var $subject;
  var $message;
  var $contentType;
 
  function clsMail() //init
  {
      $this->to        =    "";
      $this->from    =    "";
      $this->cc    =    "";
      $this->bcc    =    "";
      $this->subject    =    "";
      $this->message    =    "";
      $this->contentType = "html"; // text, html
  }
 
  function isemail($email)
  {
      // regx to test for valid e-mail adres
      $regex = '^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]{2,})+$';
      if (eregi($regex, $email)) return true;
      else return false;
  }
 
  function send()
  {
      // check if e-mail adresses are valid.
      if (!clsMail::isemail($this->to)) die('ERROR: Invalid To e-mail adres');
      if (!clsMail::isemail($this->from)) die('ERROR: Invalid From e-mail adres');
      if (!clsMail::isemail($this->cc) && !$this->cc=="") die('ERROR: Invalid CC e-mail adres');
      if (!clsMail::isemail($this->bcc) && !$this->bcc=="") die('ERROR: Invalid BCC e-mail adres');
     
      // To send HTML mail, you can set the Content-type header. html is the default
      $headers  = "MIME-Version: 1.0\r\n";
      if ($this->contentType=="html") $headers .= "Content-type: text/html; charset=iso-8859-1\r\n";
      else $headers .= "Content-type: text/plain; charset=us-ascii\r\n";
     
      // additional headers  for From, Cc and Bcc
      $headers .= "From: ".$this->from."\r\n";
      if (!$this->cc=="")  $headers .= "Cc: ".$this->cc."\r\n";
      if (!$this->bcc=="") $headers .= "Bcc: ".$this->bcc."\r\n";
     
      // send the e-mail
      return mail($this->to, $this->subject, $this->message, $headers);
  }

}
?>


Bagefter følgende kode:

<?
$name = $_POST["name"];
$firm = $_POST["firm"];
$email = $_POST["email"];


ob_start();
include 'reply.php';
$msg = ob_get_contents();
ob_end_clean();


$mail2 = new clsMail();
$mail2->to="$email";
$mail2->from="fromEmail@someplace.com";
$mail2->subject="Tak for din tilmelding";
$mail2->message=$msg;
$mail2->contentType="html";

$mail2->send();

?>

Problemmet er at den sender ikke som html. Min mail kommer til at starte med:
Content-type: text/html; charset=iso-8859-1 From: someEm@il.com

Dvs. at den visser ikke html og ikke hvem det er fra.
