I don't know how well locking works with NFS in general (badly I've
heard), but Dovecot doesn't require fcntl locking anymore. Setting
"lock_method = dotlock" will just use dotlock files.

1.0-test70 should work pretty well with indexes being located in shared
filesystems as long as you set mmap_disable=yes.

NFS has one annoying problem though. It can't handle the cases when a
file is deleted (or another file is renamed over it), and a process
still tries to read the file. Dovecot doesn't yet handle all these error
cases so you might see some errors about stale file handles from time to
time.

But if you're using Dovecot in only one computer you can just store
indexes in local disk and you won't have any problems.
