I am building a new CentOS 6.5 server. In the past I have just used Zimbra for ease. Not, since I am behind a pfsense box that does some IP mapping Zimbra requires a "split-dns" setup.
I thought that it might be time to cum out Zimbra and just use Postfix, Dovecot, etc. I gound a great tutorial. So I have 5 statics and the pfSense box answers to all and forwards the traffic to the correct box that has a private IP. In this case, xx.xx.xx.27 -> 192.168.1.27 192.168.1.27 is the IP address of the mail server. Am I going to still need this same "split-dns" setup? I cannot decide if it is something Zimbra needs or something I would need in any setup... Jason
