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

Yes, read it at that time, but my question is somehow different.
And over months I have solution too, but I look for a more elegant solution.
With properly set of queue_run_delay, minimal/maximal_backoff_time it's
work well, but affect other domains.
I think multiple instances resolve the problem, but ... I'm a little bit
lazy with this :)
