just a little warning for upas/smtpd users.
/mail/lib/smtpd.conf "ournets" is carte blanche
to relay email and modern windows viruses are
good at finding mail servers. so it's best
to limit ournets to the smallest possible set.
if you're not forwarding email to plan 9
from another machine with no authentication,
i believe the ournets can be empty.

it was fortunate i was watching stats when
(identify withheld) opened (identity witheld)'s
laptop.
