Hello everyone,
Our Exchange Server 2013 system has 2 servers with CAS and mailbox roles installed, which built up a single DAG.
Since last week, one of our admins keep receiving alert mails from the monitoring system, and it won't stop. Even if we shutdown the monitor server, or disable the sending account, nothing's changed. So I tried to stop that annoying mail from Exchange side.
The only thing I see that might help is the Default Frontend receive connector. It is the only connector in our system that allows Annonymous users to connect to:
But if I remove that selection, all the inbound mails from the internet cannot be delivered to our system, due to error 530 5.7.1 Client was not authenticated.
How could I rescope the connector to disallow anonymous users in our system only?
Thank you all,
