schmonz.com is a Fediverse instance that uses the ActivityPub protocol. In other words, users at this host can communicate with people that use software like Mastodon, Pleroma, Friendica, etc. all around the world.
This server runs the snac software and there is no automatic sign-up process.
I have a suspicion that in a very small way I might have recently contributed towards a minor unshittification of Meta.
I was drawn into it as an SMTP problem.
I can only apologize to the world if it actually does end up making #Meta capable of sending e-mail once more. (-:
As a #qmail user of many years, who did similar work of my own for OS/2, and who was drowned with UBM to the point of just giving up on SMTP e-mail in the 2000s; I can heartily recommend the rejection of Relay clients that do not adhere to the SMTP.
Gresham's Law trumps Postel's Principle.

I made the mistake of starting to learn about GEMINI from its Frequently Asked Questions document.
It's not aimed at people like me, who already understand the benefits and tradeoffs of static content servers. So it drives lots of points home, repeatedly, that I already know.
It's apparently aimed at the same sort of monoculture Chrome+Apache Think for HTTP that parallels the old BIND Think and Sendmail Think that #qmail and #djbdns were up against years ago.
