My company is getting ready to install Zimbra, and I was wondering. Is there a way for us to install the service so that we use one server, but can setup three domains that can be administered by three different divisions without the other divisions seeing the other two, just the server admin seeing all.

I would rather not do three virtual server if I didn't have to. Is there a way to do this and have each division manage their own domain without them having to have a virtual server install?

Thank you for any and all help!
