Hi Johntseung, As I understand, you want to create an receive connector to allow the backup application relay to Exchange server. The Exchange server with the IP address of 192.168.10.250/32 And the backup application with the IP address of 192.168.10.1/32 If I misunderstand you, please let me know. Please don’t change the local IP address to receive email. See below links. Allowing application servers to relay off Exchange Server 2007 How to setup a Receive Connector

I change the name to allowrelay and run the shell, not work.

Hi John, As per my expierence abour email relay, you shoud be avoide to put range of IP address which come under same range of Exchange server IP's. you should mentioned only very restrictive range for IP which needed. Try to use only oen IP address in allow list and then test it. If you want ro relay mail to internet recepients also then you must have to create one new receive connector and allow "anonymous access" on it. Follow below URL to do it.
