-# Client requests notification of deferral. First time of trying, we get
-# a defer but queue-time probably has not hit the 1st retry time yet, so no DSN
-# will be sent and the message remains queued. Then, claiming time has elapsed,
-# we will look again (expecting a delay-DSN to be produced). We won't see a
-# retry since the actual retry time has not passed.
