More elaboration on what’s involved in “correctly” would probably drive the point home — “this works because” vs “works for me.”

I made sure to include the word correctly in the reply. Mox mailserver tells you exactly what to do. I think mailcow does as well. A lot of people don't do it and then tell others that selfhosting email with good deliverability is impossible. You set it up once and you're good to go

It depends on whether your IP address has good reputation or not. Don't act like we're idiots, we know what SPF, DKIM and DMARC are. We've seen perfect e-mails (rated 100/100 by deliverability services) get rejected by Microsoft because reasons.

You were lucky, congratulations.

Addressed in another comment "I wouldn't try it from a residential IP but as long as you run a blacklist check on the IP before you start".

If you read one comment higher in the thread instead of reacting emotionally, I was specifically asked to elaborate on what the correct DNS meant. Please don't act like those who don't know are idiots.

> We've seen perfect e-mails (rated 100/100 by deliverability services) get rejected by Microsoft because reasons.

No, you haven't.

> You were lucky, congratulations.

What do you call consistent luck? In my case 14 years across 6 different sending domains, 4 different servers with four different hosts using two different MTAs?

> No, you haven't.

I mean I have seen 100/100 on https://mail-tester.com/ get rejected by Microsoft, yes, but feel free to call me a liar if that helps you feel better.

I've just noticed you're the guy who said that people were migrating away from US services "because it's trending"; you're obviously a self-satisfied pillock and I won't engage in further discussion with your tedious online personality
