Since recently – heh, let's call it 5-6 years – I've observed more and more that senders are unable to connect the first NDR ("your mail is stuck, we're still trying") with their original message. There's some cognitive dissonance at play here. If the bounce is not instantaneous, that NDR is a waste of resources for them. More or less the same happens with the final NDR ("sorry, I give up"), where they seem to be unable to grasp that the message was not delivered.
In my experience, this is very much the case. NDRs are just treated like spam for many senders, even if they are written in very simple language.
We often get the case where a sender complains that a message wasn't delivered, and is adamant they didn't receive any error message about it - then we look in their Trash folder, and there's the NDR.
So, in my view, you need to try for at least 3 days before giving up. If there's any reasonable chance of getting the message delivered, it should be.
(Maybe MUAs should (where possible) automatically link NDRs to messages in the 'Sent' folder, so that the user can see there that the message hasn't been delivered yet. Maybe if DSN was more widely supported, that would allow better user feedback as well.)
