Email has been turned into a by-the-corporation, for-the-corporation service. Corporations need DMARC so they can control email and the ability to spam. The spam I cannot block is spam from Google.

If you decide to think about this, you will quickly realize that email is f*ked and needs to be forked. Perhaps we need a Community Email Initiative that blocks corporations and only allows Community members.

Trust is the one thing you can't buy on the Corporate Internet.

I am sure many people will be offended and down vote this comment because they cannot conceptualize an internet without Corporations.

You can do this right now, and you don't even need to fork anything. E-mail is an internet scale protocol that's not owned or ownable, except by convention. Since you specifically want to cut out Google, and their attempts to capture E-mail are what makes rolling your own E-mail hard anyway, just go for it.

Depending on how hard you want to make it, you can slap all the parts together yourself or use something like Zimbra, Mailcow, iRedMail, mail-in-a-box.

The advantage over a fork, whatever specifically that means, is any service that needs E-mail as an identity verification, still works.

Yes, email is just completely broken. It's not private, sender identification is mediocre at best (and nonexistent without things like DMARC and SPF), and all the kludges thrown up make self-hosting harder. Spam has zero cost basically also. Nobody trusts email anymore for anything confidential, it's become a clumsy notification service "come check our portal for your real email".

It's time for a new protocol with end to end encryption and sender verification built-in. That shouldn't be as hard as it sounds, because at the time when email was invented the internet was very different. Connections were intermittent, for example I would retrieve my email once a day with UUCP (and some other people would use batched-SMTP). Which means you could not rely on the sending and receiving server being able to communicate directly. In this day and age this is possible and that direct communication opens up a lot of better crypto like key generation algorithms which require both parties to be online at the same time.

The problem is, is you don't allow corpos you will break 95% of mainstream people's usecases. So I think this is a non-starter, unfortunately, though it is a lofty goal.

You can already do this without changing anything. Just set your corporate mailserver to not accept mail from common community email providers. There's a reason nobody does this, and it's because it's a bad idea.

There is so much crossover between personal email and corporate email.

No, email is the only digital communication left where I can talk to normie relatives AND businesses without having an account on normie tech service. DMARC does not impede that at all and it not a valid cause to throw away this lucky artifact of computing history.

What do you mean “fork”? Just buy a domain and install an email server.
