Microsoft is blocking our reply to you. We’re not going to do anything to get Microsoft to do anything else, so you won’t have a reply by email. The gist of it is that you lied about having understood what the problem was, but the good news is that it’s nothing to do with you specifically. We are not the RFC police, we don’t list anything because of DNS, rDNS, SPF, DKIM or DMARC – and we also don’t remove listings as a result of listees doing anything about the same. The listing is an escalation listing against the network owner and your provider needs to talk to us directly, without you in the middle, and… not from a Microsoft-hosted email box.
