Its great, because it validates my new and innovative* principle of simply rejecting all mail of the [known]suffix.tld and prefix[known].tld sort. Not sure if microsoftstore.com was ever legitimately used for mail. Most of the other "wait thats a real company" cases were of the "but we don't want their mail anyway" sort. *) Of course, the "new and innovative" part was a lie. Its old and dead simple. I had many years ago been inspired by a well known large online payment provider deliberately sabotaging full-domain-keyed antispam measures. As far as I can tell they have discontinued playing around with domains indistinguishable from common phishing. I am assuming because phishing got out of hand and it is difficult to blame customers for not knowing the difference between ads@legit-brand-secure.example versus ads@brand-secure-phish.example.
