Just wonder what if my mail server went offline for some periods, and the sending party couldn’t deliver.

Will there be any consequences except I don’t get the mail? I tried searching but they all in the perspective of a sender and get a bounce, rather the other way around.

    The problem with this is the probability of your server being available for the next retry is fairly low.

    Usually some sort of exponential backoff is used so it might retry after 5 minutes, 15 minutes, an hour, 3 hours, 6 hours, 24 hours, 48 hours, give up.

    6-8 hours is probably too much for anything serious where you don’t want emails to just drop. It will work so if you’re just using it to sign up to sites and stuff, you can make sure your server is on to receive the verification emails and stuff. But I wouldn’t use it for anything important.
