I just unlocked ddostest.me with this tool for outlook.com, Hotmail.com, msn.com and maybe all the O365 suite.
It was fix in less than 24 hours.
Thanks for the tip

Neither Microsoft nor Google have been successful at making tools that work for low-volume mailers. They seem to think that if you're not in their club, you're either a commercial email marketing firm or SPAM.

Microsoft seems to be one of the worst offenders in terms of having a
email blocking blackbox. Good luck getting in contact with someone as
well. Throughout the years of self-hosting email they have always been
the most problematic of the large providers.
