slow down deferred destination

[Birta Levente]

Hi all

How can I slow down deliveries to specified domain after temporary deferred?



To yahoo, deliveries go through slow transport:

slow_destination_recipient_limit=10
slow_destination_concurrency_limit=1
slow_destination_rate_delay=4s
slow_destination_concurrency_failed_cohort_limit=100





Thanks

I have a list for marketing purposes and 2/3 part of subscribed users is on yahoo. When a mail fire to the list yahoo accepts first 100-200 mails, then defer, because the unusual traffic. Somehow need to slow down deliveries to this domain and after some time (say 30 minutes) try again. I tried to play with queue_run_delay, minimal/maximal_backoff_time, but as far as I can see is not applicable to specified transport, just globally. So, apart from globally set of queue_run_delay, minimal/maximal_backoff_time and another postfix instance is there another solution?
