I'm trying to remove X-Originating-IP as it's using the IP address of the router on the edge of our network, and the reverse DNS doesn't resolve to the hostname of our Zimbra server. I think this is causing some of our outbound email to be rejected by servers.
I set zimbraSmtpSendAddOriginatingIP correctly on both mta's:
zimbra@mta1:~$ zmprov gacf | grep Originating
Performed a zmcontrol restart on both mta's as well.
This header is showing up on email to my Yahoo account:
I would rather not have that ip address showing up in the headers at all. Any way to do that?
