Not just email - their identity / SSO system is just as fucked

> I bet Microsoft is single-handedly responsible for 80+% of complaints about email being impossible to host.

They are the reason I dropped self-hosting my mails. They were silently dropping some of my mails depending on the day I sent them. If they were at least sent to the spam folder, it would be easier to communicate with their users. And since a lot of their users are not technical at all, it's complicated to explain them the issue.

Don't forget Google! Gmail will hide your email for no reason no matter what you configure on Gmail's side of things. At least Microsoft has a "please remove me from your spam lists" form (that only worked for ipv4 IP addresses last time I tried).

Google is no better. It's quite absurd, they even went through the trouble of creating postmaster tools to help you manage your reputation - except that these don't work unless you have fairly high sending rates (I forget, but I think several hundred a day). So essentially they're actively hostile to personal and small business servers.

Google is in fact much worse. Not only is it as hard to send mail to Gmail users, Gmail is a leading producer of spam.

I wish I could just wholesale block gmail.com like people used to do with the early webmail providers.

I think that implies having an actual google account to do that, which is absurd.

It does and it is. Even better they might blacklist your domain in chrome and you need an account to defend yourself; https://support.google.com/webmasters/thread/382326165?hl=en...

Yahoo were annoying and I'm happy the collapsed solely because of that

It's absurd in every way. I was trying to get it to stop spamming maillist traffic. It's impossible. Global level filters enacted as admin to not spam check are ignored.
