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?
Nextcloud is great for contacts and calendar. Try it. I recommend using the all-in-one docker. Super easy to setup.
