Hi,
We must use our ISP SMTP server as a relayhost. Our problem is there
is a limit of 20 emails per minute. If we go over that limit, we are
completely blocked and cannot send other emails until there is no
connection attempt for some times (ISP refused to be more specific).
Is there a way to limit the rate per minute at which Postfix send
emails to the relayhost?

# main.cf
default_destination_rate_delay = 3s
default_destination_concurrency_failed_cohort_limit = 10
