You can put two MX like this :
machine-a IN MX 10 machine-a.network.us.
IN MX 20 machine-b.network.us.
if machine-a is up, then the mail will arrive there. If not, the secondary MX
machine-b will then receive the mail and queue it for machine-a. When
machine-a is up, you can run the queue (sendmail -q) on machine-b.
Some providers use a mailertable to put the mail to machine-a in a separate
queue (using a special mailer entry) and then run the queue whenever the
machine-a calls. It is a little harder to set up but works too.
