+echo 'Basic statistics
+
+qtime is the time spent by a message in the queue.
+
+ddelay is the latency for a successful delivery to one recipient---the
+end of successful delivery, minus the time when the message was queued.
+
+xdelay is the latency for a delivery attempt---the time when the attempt
+finished, minus the time when it started. The average concurrency is the
+total xdelay for all deliveries divided by the time span; this is a good
+measure of how busy the mailer is.
