Mail server trouble.

Wed Dec 18 18:21:33 PST 2002 — Mail server trouble. Two or more of our mail servers refused mail for short periods of time today with ‘User Unknown’ errors for at least some of the email they received. Although we were unable to make the new DB passwd lookups fail during testing, we believe that this failure is related to our recent upgrades. We’ve re-enabled NIS as a fall back user lookup method in case DB lookups fail again. In the meantime we will further analyze the failures so we can prevent them from occurring again again. -Kelsey, Eli, Russ and Scott.
