How to configure my droplet to use Protonmail as its Mail/Email server
I've setup a droplet for use as my personal file syncing solution (ownCloud) vs. relying on Google Drive, Dropbox, etc. I'd like to get an email setup merely for the purposes of my box sending me updates on installed packages, errors, etc. etc.
I've read a few articles on DO Community advising against using a droplet as an email server so I'm curious what my other options are for the purposes I've described.
If the recommendation is to not setup a mail server, I'd like to investigate whether anyone has used ProtonMail (encrypted email) as their email server instead of relying on something like Google Apps? My whole MO for setting up ownCloud was to keep *some *of my data away from Google :).
