@colinstu@birdbutt.com @TechTangents@dialup.space You say that, but nope. I've set up email with all of that in the past and Google and Microsoft will, at random, block your domain. You can contact them, get them to unblock your domain, and they will, and then you'll be blocked again a few weeks later. When asked why, they have no idea. Repeatedly. It's a single user email domain, and there's no unsolicited email going out. They have, effectively, killed federated email using 2 mega instances with overeager auto-defederaton.
