Is this still possible? Are your emails getting delivered?
Downvoted. I don't know when the downvoter tried the last time to "host their own email". Yes, DMARC, DKIM und SPF. Good luck trying to get your email deliverd to t-online or something.

They may even check if your domain has an "imprint". I kid you not. I use my own domains too, but I piggyback with infomaniak.com
Mine are. Although it probably helps to have a static IP with a 25 year long clean history.
Are there very occasional glitches? Sure. But I've seen ISPs drop everything from GMail on the floor for no obvious reason. I've seen GMail drop GMail email before. Same for every other large email provider.
To date I haven't seen any reason strong enough to push me to switch to a centralised email host. That day may yet come of course.
I've never heard of t-online before or tried to send an email there to my knowledge... if one provider I've never heard of would refuse to accept my mail if I ever sent something to them, that's more of a them problem than a me problem - but it certainly isn't the norm for other providers.
Yes and yes (if DMARC/DKIM/SPF configured correctly).
People who say it cannot (or should not) be done should not interrupt those who are doing it.
The dismissiveness is likely why you are downvoted, I'm guessing. The suggestion that because it's hard for you and therefore you're surprised others are doing it isn't a good look.
Self hosting email isn't that hard, and there are many solutions for all sorts of self hosting issues. That's a topic for another discussion, though.
Smart comment from reddit:
"The problem with selfhosting email, unlike selfhosting services like Jellyfin or Nextcloud, is that you rely on other people's servers to play ball with you, but they often don't. Or they play for a while and then suddenly decide not to without telling you. It's unpredictable and we selfhosters don't have enough control over that."
This describes it pretty well.
Selfhost does not imply residential IP.
