Looks like a solid setup, as far as I can see.

But why not use a raid1 instead of the one disk? It will increase
redundancy even more. Now I understand that in your load balanced setup
if one or a few servers' disks would die the system would still
function. But you would have to clone/recreate the system and bring it
back up. With a raid1 you would only have to replace the broken disk and
that's it (or if you had a hot spare you had to do nothing).

Netapp uses NFS I assume? How well does it work with imap? As far as I
know using imap on anything but unix format mailboxes on a networked
filesystem like NFS can cause problems due to file locking and such.

I remember reading on here that having the spool in memory isn't such a
good idea, but I forgot the exact reasons.
