we intend to install Zimbra in a test environment behind a firewall in a DynDNS domain with NAT.
Do to different reasons, we will receive and send our mails through an ISP (external mail domain).
External users should be able to access the Zimbra-server by typing www.ourcompany.com/mail
(www.ourcompany.com is hosted extenally)
Is your Split_DNS scenario as well recommended for such an environment?
Thank's a lot you for any feedback!
