Sorry I'm not following. What's the easiest?
I'm moving to the NFS so I can have a central place for file and email
storage on a system with quality hardware RAID1 and ideally fast SAS
drives. Then the email server will run on a fast efficient system with
cheaper drive and can be easily moved from system to system when
hardware fails. This way, I don't end up with mbox's on several
computers to keep track of.
