We are trying to setup Email relay so that the mail sent from salesforce will be routed through Exchange server.
In Exchange server configured new connector and whitelisted all the salesforce IP's which we got from this URL
After that we are trying to configure the Email relay in salesforce. Actually we tried with different host name but nothing is working. Where to take the host name from office exchange and where to take the port for the below image.?
Need help on this please
