I want to customize ZCS to display the external IP instead of the Internal IP 192.168.5.19. ZCS sit behind a firewall and the internal IP is NATTED to an external one. I have tried the Solution in the POST: Outgoing header address Masquerading, but it didn't work.

I am using ZCS 5.0.7 is there any other way to do this using zmlocalconfig.
Some mailservers are rejecting our going mails?

Here is a sample of the header:
