The queue/smtp plugin is only useful for delivery to a local smtpd. It
cannot be used for delivery to random MXs for two (related) reasons: It
doesn't queue and it doesn't handle errors gracefully.

See? :-)

But then it is a local domain again. If your own MXs resolve to 0.0.0.0,
fix your configuration.
(no, I'm not against writing plugins which help to detect local
configuration errors. It just seems to me that this is a very narrow and
improbable case, which doesn't merit much discussion. A general purpose
loop detection plugin is useful and was mentioned in the first part of
this discussion almost 3 years ago - what's so special about 0.0.0.0?)
