PHP code:

function is_email($email){   $x = '\d\w!\#\$%&\'*+\-/=?\^_`{|}~';    //just for clarity

   return count($email = explode('@', $email, 3)) == 2       && strlen($email[0]) < 65       && strlen($email[1]) < 256       && preg_match("#^[$x]+(\.?([$x]+\.)*[$x]+)?$#", $email[0])       && preg_match('#^(([a-z0-9]+-*)?[a-z0-9]+\.)+[a-z]{2,6}.?$#', $email[1]);}

When in need to change the order of a list use a field to store the order as an int:
