Why so few recipients per message? This just increases the total message load when a message has many recipients... > default_destination_concurrency_limit = 5 > default_destination_concurrency_failed_cohort_limit = 5 > default_destination_rate_delay = 1 The concurrency limit is ignored when a rate delay is specified. You should probably change just the "smtp_" settings, not the "default_" settings. Also replace "initial_destination_concurrency" with "smtp_initial_destination_concurrency". > transport_retry_time = 30 I've never seen anyone changing this parameter. You should should not have failing transports, and should not need to change this parameter. -- Viktor.
