Correct. Together with: slow_destination_concurrency_limit = 1 slow_destination_concurrency_failed_cohort_limit = 5 and without any: slow_destination_rate_delay which is equivalent to: slow_destination_rate_delay = 0s also don't change the defaults: smtp_connection_cache_on_demand = yes smtp_connection_cache_time_limit = 2s -- Viktor.
