          cstate=1;
       } else {
          // Its stuff which is not allowed
          return false;
       }
    }
  }
  if (cstate<1) return false;
  if (len<6) return false;
  // A toplevel domain has only 3 to 4 signs :-)
  if ((email[len-3]=='.') || (email[len-4]=='.') || (email[len-5]=='.')) return true;
  return false;
}
