Question about self hosting a mail server at home - if my internet goes out at home, all mail sent to me during the outage would be undeliverable, right?
For a paid host, what would be a reliable and cheap option?
You usually can't fully self-host a mail server (like literally in your house) because most residential ISPs block port 25 to prevent spam/abuse. You can use a third party relay service like what Helm offered, but most people "self host" via a cloud provider or a web host.
Email will be retried over the course of like 72 hours. That's why the failed to send email from the host master is usually really delayed. That said your local ISP will likely block the port. You can however ask them for it. They might charge you.
If your email server is offline then mail won't be delivered. The sender's server will retry as other have noted, but how often and how many times varies. Hosting at home, even when possible, is not a great idea in my opinion.
There are endless options for hosting out there, I don't want to name names since I only really have experience with one.
