Excessively massive values will outcome within the lack of non-delivery notifications, when a bounce message measurement exceeds a neighborhood or distant MTA’s message measurement limit.

Different recipients are delivered in parallel, topic to the process limits laid out in master.cf. Use transport_destination_rate_delay to specify a transport-specific override, where transport is the grasp.cfname of the message supply transport. With a corresponding per-destination recipient limit equal to 1, the speed delay specifies the time between deliveries to thesame recipient. Use transport_destination_concurrency_positive_feedbackto specify a transport-specific override, the place transportis the grasp.cf name of the message supply transport.
