All emails from one specific domain are being rejected by Exchange 2016 server with the following error:
host said: 554 Spam email. Email Session ID: {XXXXXXXXXXXXXXXXXX} (in reply to end of DATA command)

I have added the domain to the safe senders list but the problem persists.

The rejected domain is not black listed on any list.
