suppose there's a message that crashes the receiving SMTP server. (This happens
a lot more often than it should, unfortunately.) If you implement a "oldest
first" or "most often retried first" strategy along with strict "always send
every pending message once you get a connection open" policy, you can end up in
a situation where the problematic message ends up blocking other messages which
would work if you tried them first.

The lesson here is that any 'retransmission' scheme needs an exit strategy, perhaps better thought of as a means of internally routing around a blockage...
