Sorry, but the MX records merely give weighted deliver preferences,
if the user is not on the first mail server it gets bounced. The second
mail server only kicks in if the first is unreachable. Sounds like
someone needs to buy some books like DNS&BIND 3rd Edition (O'Reily)
and/or if use Sendmail the "bat" book (also O'Reilly)
