Email is already fucked. In my experience Gmail often failed to receive emails from services like Yandex and Zoho. Plenty of people here that setup their own servers, and know what they are doing, getting randomly blacklisted.
Maybe it's fine if email is not central to your life or business but if there's even a, let's say, 10% chance of my emails not getting delivered to Mr Google I have no other option than to bend the knee.
It's a tragedy. The people who designed SMTP went to insane lengths to make sure mail was delivered. The people who initially implemented it did the same. Then the "free" mailbox providers fucked it all up. I host my own email, and I now have no clue as to whether it will be delivered.
I have everything properly set up, and wasn’t blacklisted once in any service since 2002.... until 3 months ago, when Google decided to blacklist my domain, but only randomly (e.g. mails sent to same person on same day get delivered to inbox or spam seemingly based on a coin toss).
The only clue I have so far is that in some discussion, it was mentioned that google penalizes a domain of a lot of different emails from it get forwarded to google - and I do have my catchall forwarded to a gmail box.
We now live in a world where google can make you and your communication channels disappear, and they don’t really answer to anyone.
That requires hundreds or thousands of emails from your domain per day to show anything - which is useful if you run a major service, but for the use case of "every person hosts their own email", it’s not exactly useful.
