L’impossibilità di avere oggi un server email in self-hosting

Ho letto questo articolo rilanciato su Mastodon da cedmax che mi ha lasciato senza parole, una cosa di cui non ero al corrente. L’articolo completo è disponibile al link indicato dopo la citazione.

Email is now an oligopoly, a service gatekept by a few big companies which does not follow the principles of net neutrality.
[…]
Over time I realized that residential IP blocks were banned on most servers. I moved my email server to a VPS. No luck. I quickly understood that self-hosting email was a lost cause.
[…]
I lost. We lost. One cannot reliably deploy independent email servers.
This is unethical, discriminatory and uncompetitive.
[…]
You cannot set up a home email server.
You cannot set it up on a VPS.
You cannot set it up on your own datacenter.
[…]
The era of distributed, independent email servers is over.¹

E pensare che è da tanto tempo che sogno di avere il mio server email in casa o comunque in self-hosting.
