LOCAL(8) DELIVERY RIGHTS says: "Deliveries to external files and
external commands are made with the rights of the receiving user on
whose behalf the delivery is made."
So I put "nottheoilrig: /mnt/nottheoilrig/" in /etc/aliases (alias_maps)
thinking mail for user nottheoilrig would be delivered to
/mnt/nottheoilrig/ as UID nottheoilrig.
In fact it's being delivered to /mnt/nottheoilrig/ as UID nobody (65534):

What am I missing? Thanks!
