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. - erik
