You might also want to look at using ETRN if you have two mailhosts that are
not on the same network. You could queue the mail on the backup host and
then once the primary mailserver comes back up it can issue an ETRN command
to the secondary server telling it to unfreeze the mail in the queue for a
certain domain and attempt to deliver it.

I hope that makes sense. There is some documentation in the Exim FAQ if you
would like more information.

Hope that helps.

PS. Are we able to buy exim shirts yet? If so, I would be most interested
=>.
