See https://www/postfix.org/QSHAPE_README.html When a destination is unable to handle the load even after the Postfix process limit is reduced to 1, a desperate measure is to insert brief delays between delivery attempts. * Postfix version 2.5 and later: o In master.cf set up a dedicated clone of the "smtp" transport for the problem destination. In the example below we call it "slow". o In main.cf configure a short delay between deliveries to the same destination. /etc/postfix/main.cf: transport_maps = hash:/etc/postfix/transport slow_destination_rate_delay = 1 slow_destination_concurrency_failed_cohort_limit = 100 /etc/postfix/transport: example.com slow: /etc/postfix/master.cf: # service type private unpriv chroot wakeup maxproc command slow unix - - n - - smtp Here, the delay is 1 second between deliveries. Use "postfix reload" command sparingly, as it resets the rate delay timer. Use the command only when you change master.cf, or the rate delay.
