You don't need a sledge hammer to kill a fly. NFS mounts, by default,
do not allow root access across NFS boundaries. But WAIT! We HAVE the
technology. When your server exports the file system to the client(s)
mounting /usr/spool/mail, use options to allow access=root. If you
have SunOS, check the manual on mount and export and exportfs. For
other Unix systems with NFS, you have to check for the implemented
options. Ultrix uses somethings like " -r=uid " in /etc/exports.
The technology is NOW.

Forget this stuff. Too complicated.
