I just learned about Zimbra, and after taking a look, I decided to give it a shot as it seems to be a very viable replacement for Exchange in my personal environment.
The problem is, right out of the box, it doesn't seem to work right. I started by creating a new VM and installing CentOS 6.4 Minimal on it, transferring the Zinbra install and patch files, VMware Tools, etc, installed VMWare tools (and all the components required to install VMWare tools), disabled the firewall, ran the Zimbra setup to see what packages were missing and installed the missing packages, edited the host file to include the servers IP and name, then ran the installer again.
I've set it up from scratch twice, and both times I've had different problems. The first time, I got a 'Some services are not running' message, and when I looked, ALL of the services were reported as not running. I decided to rebuild it from scratch again, going through all of the same motions. This time, I got a message about a port conflict during the setup, although I can't figure out what it is/was for the life of me. I set the password and applied the config, and the web interface came up - only to get the same 'Some services are not running' message, but this time, only the MTA is reported as not running...
With TechNet going away, Zimbra looks like a very nice option to replace Exchange, but it concerns me that a fresh installation on a brand new clean machine doesn't work right... I've always been a Windows admin and am not super skilled with Linux, however, I'm trying to learn and can do basic work in Linux when I can find instructions on how to do things. Is it something I'm doing wrong or missing? Should I be using a different Distro?
Any help or thoughts would be appreciated.
