I know there are alternatives like proton mail, tutamail, mailbox.org, etc… But what would be the issue if I create an email using my personal domain, stored in my hosting… maybe encryption? It seems that no-one even consider this option, but I am not sure why…
What would you suggest?
You can point your domain on any hoster like mailbox.org. There are a lot of benefits at not hosting your own mailserver.
A major downside is that email is not encrypted and Email usually contains very sensitive personal information.
