IIRC, mount permissions (i.e., what IP addresses, root UID mangling, etc)
are set per filesystem. Given a filesystem structure like this:

Filesystem 1K-blocks UsedAvail Capacity Mounted on

To export a single filesystem multiple times, *all* of the attributes must
be the same. If they aren't the only person you are fooling is yourself,
since once a filesystem is NFS exported, it is open to the world.
anyway the syntax for what you want is:
/var /var/mail some.machine
