hі! i have this in my main.cf:
destination_concurrency_feedback_debug = yes default_destination_rate_delay = 10s default_destination_concurrency_limit = 10 default_destination_concurrency_positive_feedback = 0.05 default_destination_concurrency_negative_feedback = 1 default_initial_destination_concurrency = 1 The goal is that the server starts sending mail every 10th second, then after 50 mails increase to 2 mails every 10 seconds, until it sends 10 mails every then seconds, ramping up slowly. But i dont see that happen. If i have default_destination_rate_delay set to something other 0s it keeps sending mails every 10s only, no increase in volume. Sometimes, without any aparent errors occuring in the delivery queue of that domain, it pauses the delivery to that destination domain alltogether. from the debugging info i dont see any increase of the "success" value in limit 5 window 5 success 0 failure 0 fail_cohorts 0 how can i combine the "slow start" with the slow sending with pauses inbetween? i use postfix 2.5.5-1.1 from debian testing.
