All this is red tape since no matter if the sending mail server is
covered with SPF, DKim, DMarc and RDns they only allow mails from a
white listed list.

Example, my mail server obeys all of the above and after verification
from google mails from my server is accepted by gmail. My mail server
has also been verified by Microsoft and all mail service owned by
Microsoft or hosted by Microsoft accepts mail from me except hotmail.
It claims that my mail server is on their black list! From a high
placed source in Microsoft - which is a former student of mine, I know
that such a liste does not exists!

The only other mail provider which shows same behavior as hotmail is
gmx.de

So all these issues often boils down to that big mail providers do not
like mail providers which does not spy on there customers and sell
their data to the highest bidder.
