Shawn,
 theoretically it sounds like a good idea, practically it is not. first,
nfs locking is advisory, that is several processes writing to the same
file are apt to destroy it, and mail resides in *one* file. if you want a
central repository, select a machine that will carry all the mail (not
necessary the same as mail server), run imapd on it and use a webmail
setup. this allows you access to mail from just about anywhere and all
the mail sits on one machine (this machine needs to have all the user
accounts). this setup is pretty straightforward and it works well. julius
