Thanks,I did realize after I sent the email that what was probably happening was the delay was the overiding controller, and not working as in addition as I thought it would.
Is there a way to do combine the delay w/ the concurrency? Like two simultaneous connections each doing one email per rate delay? I'm trying to help some folks out w/ sending to yahoo and trying to see what options I have as far as rate control. ________________________________ From: owner-postfix-us...@postfix.org <owner-postfix-us...@postfix.org> on behalf of Wietse Venema <wie...@porcupine.org> Sent: Tuesday, January 17, 2023 7:17 PM To: Postfix users <postfix-users@postfix.org> Subject: Re: Understanding concurrency limits Sean Hennessey: > In master.cf > smtp-tar unix - - y - 1 smtp > -o syslog_name=postfix/$service_name > > In main.cf > smtp-tar_destination_rate_delay = 600s RTFM, this puts 600s delay between deliveries as in: deliver one meessage wait 600s deliver one meessage etc. The scheuler could warn when concurrency >1 will be ignored, but given that "default_destination_concurrency_limit = 20", that would create a lot of noise.
