So MSFT continues its attempts to extinguish the smaller providers while ostensibly being in favor of "diversity" and open source.

How about blocking MSFT in Germany for anti-competitive practices?

Wait but if microsoft completely blocks a cloud provider wrt. any mail sending this is a form of illegal hindering of competition as far as I can tell.

Yeah. And nobody can do anything other than wait until their period has passed. I had to mail Hetzner multiple times because of this.

I seriously doubt that only one IP of Hetzner sent spam but unfortunately it seems to be pretty common for email providers to soft ban VPS IPs.

I don't know how much spam come from cheap hosting services but between the hacked servers and servers rented by spammers it's probably a lot.
