   I'm trying to add DNS MX validation and I must be missing something, because I can't get it to work...

   In the common-validator.php file after line 28, I added the following...

   //validate DNS MX record
   function domain_exists($value) {

   list($user,$domain) = split('@',$value);

   if (!checkdnsrr($domain,'MX')) {
   return 'Sorry, This domain is not valid';
   } else {
   return true;
   }

   }

   And in my post-functions.php file I added the following after $rules[$element_name]['email'] = true; on line 296 since I only want to do this on certain forms:

   if ($form_id == '3') {
   $rules[$element_name]['domain_exists'] = true;
   }

   Any help would be appreciated.

   Try changing your function to become like this:

   function domain_exists($value) {
   
   $value = $value[0];
   list($user,$domain) = split('@',$value);
   
   if (!checkdnsrr($domain,'MX')) {
      return 'Sorry, This domain is not valid';
   } else {
      return true;
   }
   
   }

   No luck... Anyone else ever implement this and get it working?

   Hmm.. have you checked if the function checkdnsrr($domain,'MX') already worked fine on your site?

   If you are using Windows server, this function only available since PHP 5.3.0
