I've tried several changes in my main.cf, none seem to do the trick for me. Here is some of my postconf output, hopefully the important/relevant parts: Always provide full postconf -n output... Anyway, I think what you want to set is delay_warning_time. I set mine to 15 minutes: delay_warning_time = 15m This was dictated by my boss... personally, I think 2 or maybe 4 hours is enough, but I agree, 5 days is way too long for me... I'd love to be able to provide ongoing warnings... 15m, then 4 hours, then 1 day, etc... but don't think this is possible in vanilla postfix (love to learn I'm wrong)... -- Best regards, Charles

I set mine to 15 minutes: [CM] delay_warning_time = 15m Seems pretty reasonable to be, though I may set this to 90m instead. Thank you Victor and Charles. .vp

Normal in certain cases (typoed domains, mostly). Why not use: delay_warning_time = 1h Great point. What about for undeliverable address: unknown user:? I set delay_warning_time to 120m and after 2 hours never received any warnings at all that my email was rejected due to being sent to an undeliverable address, user unknown in this case. Finally, prior to my change to delay_warning_time, postconf showed it set to 0, which I suppose does *not* mean instantly? .vp

Well, the remote side apparently had unknown_local_recipient_reject_code = 450, which I am assuming had me retrying, I too had this setup this way until this afternoon. I've just sent to a different recipient and one that I know has unknown_local_recipient_reject_code = 550 and in deed I received the bounce instantly. Does this mean that if a remote site has this set to 450 that I will keep trying for 5 days, or however long my maximal_queue_lifetime is set for? What do I do in the case of misconfigured (are they?) MTA's? Thanks, .vp
