Hi Experts,
We are running exchange 2013 in Hybrid with office 365
We have internal applications which required to send email without authentication like printer some apps etc....
So we created a recieve connecter and allowed only HLB virtual IP ( Created for Relay) in the connector selecting anonymous Permission group
Now there is a app which is sending email outside domains, which may cause issue.
How do I block these anonymous emails sending outside but allow internally
