Even if there are 1 million independent email servers, if Google, Microsoft, Amazon, and Apple send, receive, or pass along 98-99% of emails, there's still a fair bit of centralization in the network which should be acknowledged, though this is admittedly not the same as the protocol being inherently centralized.
- atoav 1y agoHow do you messure this? Every university in my country has thousands of mail accounts that are constantly used and having worked at an university IT department I have never heard of any numbers collection coming by to ask us how many mails our users sent to each other. I wouldn't be surprised if that percentage was made up by the big ones to give you the feeling that self hosting mailservers is useless.
- pcthrowaway 1y agoYou're probably right, I hadn't considered the volume of mail being sent within institutions that might host their own mailservers, so maybe we should say more than like 50-60%. Is it still a good example of federation though if a vast majority (99%?) of mails between such institutions or outside of orgs large enough to have a campus, tend to go through Microsoft/Google/Apple/Amazon?
