Follow just saw this again today on HN. Google refusing mails from a mail provider without giving any meaningful error message or reason.

We had similar issues with microsoft and our mailserver (whole hetzner ip space was blacklisted there)

E-Mail is federated in itself but as there are large "instances" like google and microsoft they can make it feel like a centralized service and make it very hard to run independent instances by dropping their messages.
