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…
