He recommend Proton Mail. However there's been a few comments lately on hn that its privacy isn't really sufficient. I'm wondering what I can use instead? Self hosting seems not only burdensome but likely less secure.
I also have an old Proton Mail account that is used occasionally. Can't complain about that either.
I don't want my mail being scooped up by Google-scale orgs. Don't really have any other privacy requirements beyond that.
Your mileage might vary.
You can selfhost just IMAP storage, and pay an email service provider to receive and store your mail for you, periodically archiving it to your own long term storage and removing it from the provider.
