-# This single retry rule applies to all domains and all errors. It specifies
-# retries every 15 minutes for 2 hours, then increasing retry intervals,
-# starting at 2 hours and increasing each time by a factor of 1.5, up to 16
-# hours, then retries every 8 hours until 4 days have passed since the first
-# failed delivery.

+## Note that retry rules specify when an address / host / mail should
+## become eligible for retrying. They do not specify when the retry
+## attempt will actually occur, as this is dependent on queue run
+## frequency and timing.

+# For mail to debian.org addresses, this rule starts with
+# retries every 10 minutes for 2 hours, then increasing retry intervals,
+# starting at 2 hours and increasing each time by a factor of 1.5, up to 16
+# hours, then retries every 8 hours until 14 days have passed since the first
