*With ‘better’ I mean that an encrypted solution is adequate in these cases because the mails are on other servers, and the companies/servers depend on the jurisdiction where they are located. But by hosting a mail server at home, even unencrypted, we are 100% in control of our data.
PS: is there a self-hosting mail server solution that stores everything encrypted? I already self-host almost everything I use, but not email.
Self-hosting has other drawbacks. Your need to maintain your server, you need a steady internet connection and a steady power supply. These are things providers like Proton and Tuta deal with for you.
