New tenant and domain classed as phishing

malmesater 
hi
what i want to show,
that there is someone sending spam from, or try to send via relay, or faked IPs, or a combination of these, with the name of these servers.
perhaps it is possible to report it to microsoft and ask them.
i am to lazy to do it, as my mailserver is a very small one in germany and these kind of "spamfloods" will normally go away in view days or weeks. as you see my server blocks it already.

your problem is the other way around, you want to send.
perhaps you are able to contact microsoft and show them also my findings and ask about the cause of the "pishing error" with your settings (if they have questions, want some logs, i am able to help them).

short explanation
i found your thread by searching the IPs(beginning with 40.107. .....), at google, trying to find similar "victims" as me and what they do about it, but can't find any other message about it yet.
i do not know if your problem is connected with mine.

i wish you a lot of passion, if you get in contact microsoft.(by the way it is possible, but the information will not be easy to find)
