I still haven't found the cause, but occasionally the server fails to
resolve a domain, and instead of timing out it just returns NXDOMAIN,
which apparently prevents clients from trying an alternate server.
Is this a known problem? It's causing sporadic issues for our mail
servers and Windows clients.
