Consequences of a mail server offline? (lemmy.ml)

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.

Some things to consider:

  • It is typical for mail servers to retry a couple of times for maybe a day or two. The exact values can differ a lot.
  • After this time, the message bounces and the sender (sometimes) gets notified.
  • This bounce might get your address removed from newsletters.

    So noting substantial other than I don't get the mail and might get kick out of newsletters?

    Correct. But at least for me, even the low risk of some e-mails getting lost is pretty substantial.

    if you need more reliability you can always use a second mailserver as backup, add a second mx record to your domain and if the first one is not responding the second one will be used. there is no limit of how many next servers there can be specified afaik.

    Sure. But you could also just not turn off the mail server for a start ;)

    True, but I had the crazy idea of running it on my laptop that goes with me.
