What I am proposing is that community email servers can talk to each other. I have email servers setup - all the hoops - for my community. I want others to set up community servers and be able to interoperate. My server can send and receive from other communities. No corporations, no tracking. If your sever spams it gets dropped from the federation. Yes it is more complex, and there will be problems and issues. But hey, if we can have crypto currency why can't we get emails?

let's say this federation has three communities, a, b, and c. you run a, I run b, and my spammy friend runs c. C is my friend, and I'm going to keep allowing him to send me email, but you drop him, because he spammed you.

that's literally how email works today, unless the federation can supersede my authority as an operator to choose who may send/receive with me, at which point it'd stop being a federation anyway.
