A former coworker of mine has made a lot of contributions to a project called sovereign: https://github.com/sovereign/sovereign https://github.com/sovereign/sovereign > "Sovereign is a set of Ansible playbooks that you can use to build and maintain your own personal cloud based entirely on open source software, so you’re in control." It makes use of all the techniques described in the article for e-mail, including dovecot/postfix, DKIM, encfs. I decided to give it a try a few weeks ago. I went and bought a $10/month linode instance and a domain name. By the end of the day I could send and receive e-mail. letsencrypt was a big help here, because it allowed me to get TLS for free. I always assumed that hosting your own e-mail was virtually impossible but my friend has been hosting his personal e-mail and the e-mail for his company for around two years now, with linode and sovereign. He says that the server requires maintenance about once every six months. This doesn't really protect you from the three-letter orgs, as other commenters here have mentioned. But it does put you in control of your own data, and prevents analytics of your own inbox by corporations like google.
