Interesting history and analysis of SMTP's history. How can we prevent fedi and other open protocols from suffering the same fates?

I am running my own mailsever for over 10 years without any blacklisting problems...

Right, but try doing that with a 10 day old server created in 2024. That's the hurdle people are referring to.

This works, too. It's actually common that your dmarc-entry needs some time to be accepted everywhere. Wait a few days more and your mails don't hit the spam folder on google and outlook.

Just did that a few months ago. No issues yet.

I've run into one issue in my time on a weird self hosted platform. The DMV said "oh. Let me call IT and get that unblocked" and then they did and it was done. All other times have been fine
