No, it’s not selfish, although I’m sure that’s what he would want you to think. You should do what is best for you.

Grayjay can get around that issue in most cases.

Yep, pretty much. It used to be doable, but these days it’s very difficult. It’s certainly not impossible, but one slipup and you could get on the deny list forever. It’s just not worth it, since emails are usually pretty mission critical, imo.

Fedora CoreOS is meant to be just for containers if you want to go this route.

Distrobox perhaps? Not sure about the android side of things. For true “sandboxing” something like docker is probably your best bet.

It should be noted that email servers, no matter the setup, require you to follow strict standards to achieve proper delivery. It’s very easy to get blacklisted, and it’s next to impossible to get off of said blacklist once you’re on it.

I used to host my own mail server with this, but it got to be too much to get my emails to actually send. I was always wondering if my email was actually delivered or if it was silently bounced or sent to spam. Email is the only thing I’m not willing to self host.
