i found a solution myself. i thought i should post it. it is not actually a solution.
i just put an @ before the list and fsockopen functions so the errors are no longer shown.

[code]
function checkEmail($email)
{
  if(eregi("^[a-zA-Z0-9_]+@[a-zA-Z0-9\-]+\.[a-zA-Z0-9\-\.]+$]", $email))
  {
      return FALSE;
  }
 
  @list($Username, $Domain) = split("@",$email);

  if(getmxrr($Domain, $MXHost))
  {
      return TRUE;
  }
  else
  {
      if(@fsockopen($Domain, 25, $errno, $errstr, 30))
      {
        return TRUE;
      }
      else
      {
        return FALSE;
      }
  }
}
