Our server IP is a.b.c.67 and the gateway IP is a.b.c.65. Both are Public IP Address in 29 bit subnet. Our problems is that receipient server (gmail, yahoo, etc) detect gateway IP as originating address. We need to know, is the problem caused by server configuration or network configuration? Our Gateway handled by Mikrotik Router that bridge the Public IP to Server host. Thanks

Detetcted IP Address
It seems that your router is connecting outgoing connects via the public gateway IP-address and not via public Mail-Server-IP-Adress.
Incoming connections are not the problem?
Configure your Router for outgoing connects from your Mailserver to send it over public mailserver Address and not via standard gateway. But only for outgoing connects.
Mail-Server -> (internal IP-Address) Router -> (external IP-Address Mailserver) Router
Example for outgoing connections:
Mailserver internal IP-Address (192.168.200.5)
|
Router internal GW (192.168.200.1)
|
Router external (a.b.c.67)
Its a router config Problem. Not Zimbra or Zimbra-Server Problem
