To have the backup server send the messages to the primary, just use a
dnslookup router.

You might also want to have the backup server somehow validate the local
parts, though, otherwise you will probably find that valid addresses work fine
but invalid addresses (at your domain) are accepted and then bounced by the
backup server. There are all sorts of ways to do this; having the backup
server use recipient callouts (with defer_ok) is simple and effective.
