I wouldn't recommend sharing the Zimbra install. That's not to say it can't be done. It's simply not meant to be done and therefore may cause lots of headaches. I have two Zimbra servers up and running on dedicated machines with absolutely no issues - but then I tried to follow the Zimbra team's instructions and advice as closely as possible.
I'm sure a Linux "guru" would be able to share the install but I'm not quite that adept... yet.
Good luck with your Zimbra experience and enjoy. |
