Set up your own mail server

Claim back your mail

Most people have casual emails such as Gmail, Yahoo, Microsoft or other free providers: that might be OK, in a sense. Most companies in the IT industry have their own domain names for professional use, but they entirely give up the ownership of their data by subscribing to the same services that random users have for unprofessional, sporadic use.

This is stupid.

I think companies and institution should by default own their data.

Managing your own mail server is a way to own your data.
