You are too flexible. :-) I am a "BSD" person.. can't imagine trying one of the many distros.. of Linux..
What I want is something that will be bullet-proof in deployment, and I'm not sure that out-of-the-box Linux is, right now.
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.
