I am running an old POSTFIX solution and is busy installing Zimbra (LSD South Africa will eventually do my licensing and support).
What I would like to know, is how do I do an OFFILINE installations (with all my current mail settings running on my active server) so that I can setup my users and the environment prior to the Zimbra server taking over my current solution?
Please keep in mind that my Zimbra Installations will also be:
2. Squid Server (using squidGuard)
3. Proxy for my business.
