I see, here you can see a more detailed feedback (mostly from users though):

A customer of mine was hit with his problem, and I suggested work-arounds and to
show the customer customer's the extent of the problem.
The obvious solution would be that everyone gets a Microsoft hosted mail
service and drops independant service providers :)
NB: apart from the joke, it gets every day more complicated to manage an
independant SMTP provider, notably due to a very feelable concentration
of individuals, but also enterprises within one or two GAFAMs: unfortunately
we no longer live in an Internet world where we can say "Microsoft is irrelevant":
most universities and enterprises seem to have been lurred there.
