Actually, my idea was to delay e-mails because I don't want to read them during weekends, while I still want to read other e-mails (e.g., newsletters, login alerts). I still open my inbox once per day :-)

If anyone expends as much effort at delivery (7 days, usually, with spaced repetition) of anything these days, I'd be seriously impressed.

Modern MUAs can usually do this sort of thing, tbf.

AFAICT using the MTA is a great way to avoid "can't stop looking syndrome"... I can't see the content of e-mails if all I see is 'rejected email from [email protected]' in the logs. Ofc, you need to reject them before they enter the queue -- that's the point!

Anyway, I don't particularly begrudge anybody solving problems in a way that works for them.

Yup. "Try as best as you can (to eventually deliver, not ASAP), but if you can't - well, all content in transit is considered ephemeral."

I mean, I do battle with notification-FOMO as much as anyone; if it works, go for it. I would just be tempted to poke at the rejected queue.
