i am also having problems delivering to microsoft domains since sunday.
i am in their SDNS program and it doesn't show our domain as being
blacklisted.
i contacted their engineers via
https://support.microsoft.com/en-us/getsupport?oaspworkflow=start_1.0.0.0&wfname=capsub&productkey=edfsmsbl3&locale=en-us&ccsid=636383072583611450
. The response was pretty quick but it doesn't seem to have fixed anything

We are having difficulties while delivering mails to Microsoft's domains like
hotmail and outlook.
They appear to have a DNS problem which is causing outbound mail to fail. Their
SMTP servers are using non-existent hostnames when they say HELO. This DNS
brokenness may well be wreaking havoc for those using SPF, DKIM, etc when
speaking to M$ mail servers or receiving email from them.
