Thanks Oliver, I remember that earlier discussion well, thank you. I was concerned that there was an additional false positive use case about which we were unaware (there seems not to be).
I agree that many tenants fail to follow Microsoft's guidance, and so our policy would indeed block those senders. Our customers are 99% B2B, with higher standards than most I acknowledge. They would be in a position to notice a false positive, and are supportive of our insistence that such a tenant conform to Microsoft's guidance. I accept that our strict policy may not be appropriate for all ESPs, but it is for our customer base. Regards, Mark -- _________________________________________________________________ L.
