16// the mailer's worst-case delivery time from notify's own named constants
17// (attempts 1..MaxAttempts-1 each wait RetryBase<<(attempt-1); the
18// MaxAttempts'th failure is dead-lettered immediately, per notify.Mailer.Run)
19// rather than a copy of the numbers, so either side moving breaks this test.
