There's definitely coordination.  The attempts come in one after the
other, with no overlap -- if you look in my mail log, you'll see
that the delivery attempts are nicely serialized.  Machine 1 tries, fails.
Then machine 2, then machine 3, etc.  If they were completely ignorant
of each other, there would be more overlap as several machines attempt
simultaneous delivery.

Regards,

David.
