They’re not using a different protocol for delivery, they still use IMAP and SMTP, but other mail clients can’t decrypt the message content from Proton because they don’t have the keys (and nor do Proton). Proton do supply a “bridge” app if you want to use your Proton mail with a desktop email client, which handles the decryption between your computer and Proton by accessing the Proton encryption keys on your computer.

TLS is like a padlock on a box, and you have the key. Encrypted content is if the letter in the box is also written in code, needing another key to translate into plain language.

How does one send a spam email that passes SPF and DKIM if one doesn’t have access to the DKIM private key, or the DNS server to edit the SPF or DKIM records?

Can I offer you some Star Sector (https://fractalsoftworks.com) in these trying times? It’s a top-down view with more real-time strategy and RPG to it than first person space sim, but the exploration component is there in spades and scavenging ships to add them to your fleet is pretty fun and satisfying. I’ve been playing it obsessively the last few weeks.

I didn’t know about the secret exploration stuff in Freelancer, I never found wormholes or what have you. Might have to load it back up! Or the FOSS version “LibreLancer”, thanks to all who commented so far for mentioning that 😊
