You are too flexible. :-)
I am a "BSD" person.. can't imagine trying one of the many distros.. of 
Linux..

I had pretty bad experience with NFS.. but Netapp server with FreeBSD client 
is likely very workable.

How many mailstores do you plan to have?
Is it 1 netapp and many mailstores?
How many domains? ie.. one large domain or many domains.

I am asking because if you were doing multiple domains you may be able to 
break the work down by using imap/pop3 proxies

Something like.

Front end machines running perdition/courier/dovecot proxy

multiple mailstores handling multiple domains

Netapp

This way only one mailstore will deal with a series of domains and you will 
not have to worry about locks since only one mailstore will deal with a set 
of files.
