Have you considered the following:
- Inbound mail spends a fraction of a second in the queue.
- Inbound mail spends days or weeks or more in the mailbox.
- If an MTA goes down, mail flows via alternate MX hosts.

I'm currently running a pretty basic high-availability configuration for
our mail server (postfix) - it simply runs in a Xen virtual machine,
with mirrored disks across two machines (DRBD), and failover of the VM
