Hi. I used to run a mail server around ten years ago and started running it again last year.

I have three receive mail domains and one mail domain that does both. It is /so/ much harder now.

1. One domain that I let lapse for a few years is currently being impersonated by various servers.
2. There are periodic and frequent attempts to login via compromised credentials
3. Domain and IP reputation is a thing now.

The first challenge is to find a server that will let you host email but that isn’t on a spam list. Some spam lists you can apply to get off, some you can’t.

Then you have Microsoft. With Google you get thrown into spam. With Microsoft, your email just doesn’t make it. Their support is non existent.

I switched servers three times and took another month to get to Microsoft hosted inboxes. And your email is useless without Microsoft due to all the businesses that use Microsoft as a mail provider

And then if you use the mail app on iOS you quickly discover that you have to manually refresh because just on iOS, the mail app doesn’t support imap push or whatever it’s called.

I still haven’t found a good SELF hosted solution. There are third parties you can use but I don’t want to do it. There used to be a few popular solutions but development went off and on so some distros dropped it.

I’m still on Google and Apple calendar because I haven’t found a solution for that.

Of course there are solutions that encompass it all, but I am running postfix and dovecot and finally got it stable so I’m not running mailcow or whatever…

I’ve been using my own domain pointed at Inbox.eu. They’re based in the EU and I haven’t had any problems, I pay for 2 users, the price is something like 12€ per user per year, so it’s cheap enough for me.

I use Addy.io with my own domain. The reason is that I don’t want to depend on Addyio.

If you mean self-hosting email, then good luck.

It’s a lottery with the IP and even the IP space you get, whether anyone will actually receive your emails.

I hosted my own for a few years, but god fed up telling everyone to dig through their junk folder for my emails, and not being responded to very often, probably because of just that.

Maybe some providers have it better, but I tried a few and each was just not good. I really think Microsoft, Amazon, Google and other big players have intentionally separated the good, trusted IPs, ones they use for email services specifically, and made the other worse

Get your own domain. Don’t host your own.

I’ve had the same domain on gmail, proton and now purelymail.

You can point your domain on any hoster like mailbox.org. There are a lot of benefits at not hosting your own mailserver.

I’ve been using my own cloud-hosted SMTP relay and Zimbra server for over a decade now, and I love it.

There can be a bit of a learning curve, and in some cases sites won’t accept mail from cloud-hosted domains. I add those domains to a rule in sendmail that sends those domains through Amazon SES, and then they get accepted.

If you do go this route, just make sure that your recovery emails or 2FA for things like your registrar go somewhere else. If your cloud provider pulls the plug on you or something you don’t want to be stuck waiting for an email that can’t arrive.

I love the level of control that I have over my email and wouldn’t have it any other way.

tl;dr: steep learning curve, but worth it in the long run. Keep gmail as a recovery/2FA account or something, though.
