Going back to my first mail, the long and short of it is:

"However, we plan to run a cluster of these servers anyway, where we 
will keep domains/accounts going to a particular server but fail over to 
one of the others in case of an outage."

We have a new Netapp, and have been running our email off NFS for years 
without problems. To be fair, we haven't needed shared storage before, 
but we spent a lot of money on reliable storage, so there the data 
stayed. What sort of problems have you run into? So far in my dovecot 
testing I haven't had any issues either.

We did try a few clustered filesystems on a SAN mount instead, but the 
results were, at best, poor.
