 * Hi,
 * I need to check before submitting if the domain of given e-mail id exists? So
   for this where should I place the following code:
 *     ```
       if(isset($_POST['text-4e9010aa8ab63'])) {
       $email = $_POST['text-4e9010aa8ab63'];
       $domain = strtok($email, "@");
       $domain = strtok("@");
       if (@getmxrr($domain,$mxrecords))
          echo "This ". $domain." EXIST!";
       else
          echo "This ". $domain." does not exist!";
       }
       ```
   
 * Thanks
