i installed Zimbra 8.0 successfully on ubuntu 12.04. i have also installed apache2. Currently, i am able to access the Zimbra webclient from the LAN and Zimbra is able to send and receive mail with no problems. However, when i try to access zimbra webclient using http:// from outside the network i get this message "It works!
This is the default web page for this server. The web server software is running but no content has been added, yet".
what is the problem since both port 80 and 443 are enabled on the firewall and i have a public IP and an internal address as well. am new to linux and i need your help so that my clients can access their mail from anywhere in the world.
