Are you sure? With the default configuration, the fact that b had a
temporary error should prevent further delivery attempts to b until its
retry time has come. So if the retry time for b is 15m, there will be no
delivery attempt for the second message when it arrives.
This area of logic is notoriously complicated, so the only way to be
absolutely sure would be be set up a test and check it out.
