Hello, I wrote Postfix and maybe you should listen to what I say. I suggest that you fix the problem, namely, why commections are timing out with your relay host. Once you get rid of the timeouts, everything will move faster. Reduce smtp_destination_concurrency_limit by a factor of 2 (and execute "postfix reload"). Repeat this procedure until the timeouts go away. Wietse
