The question remains: did you hit CTRL+ALT+F3 because you needed to clean your monitor, or do you need to clean your monitor because you hit CTRL+ALT+F3?

This is pretty much the basis for the entire speed-running community. Maybe not totally different (like walking around as a peaceful tourist in Hitman), but definitely not utilizing mechanics as intended

Try a different shell, like fish or zsh, maybe. Something with really intense command auto-completion and history.

I personally use fish, it is amazing for this kind of thing.

ETA: also read up on rc files for whatever shell you are using. Creating aliases and functions based on what you do all the time is essential IMO.

Giving the would-be linux newbs the benefit of the doubt, IF they have any terminal experience at all it is with CMD/PowerShell. I don’t blame them one bit for wanting to banish all terminals into the shadow realms, they had a traumatic experience.

I don’t think the SPF / DKIM / DMARC stuff is overly complex nor the core of the problem.

It’s not the core of the issue, but the average joe that is a hobbyist self-hoster it will be.

IMO, the core issue is that there is no standard whatsoever. People just do whatever the hell they want with these records, pretty much. Microsoft and Google do it differently than each other, even.

The only solution for me is that we move on from email as a society.

Yea, if you are not willing to be meticulous about learning/understanding all the DNS stuff (SPF/DKIM/DMARC), and plan to host this at home, don’t.

I ran this same system for a very long time on a VPS and had no problems with blacklists, but I’m also a career systems engineer that maintained enterprise systems and exchange servers.

Also note how I am speaking of MIAB in the past tense…

I think the better option is to try and avoid email as much as you can, just like SMS. Outdated tech and not secure. At that point, any ol’ existing email service is good enough.
