Check IP connectivity.


To add to Paolo's comments, you should check if there is a firewall in between which is blocking port 25.

Thanks for your reply..

i can ping exchange server from CUE also server admin has created relay for this IP. but still facing the same error.

To check connectivity from CUE, try using telnet from cme router to port 25 sourced from the cue interface
