Zimbra Multi Domain with Open Source

[Ramaagcp]

I would like to migrate existing email servers (two domains) to zimbra open source edition. Regarding this setup, have few questions

1) how many public IP needed
2) do I need to manage different MX and DNS A records

Any guide explaining , Multi Domain architecture or concept.

And also guide setup this

One.

Yes.

You have two domains on one server rather than two domains on separate servers, what else is there to know?

And also guide setup this

[/quote]Yes, read the product documentation, read the wiki articles on the subject, read some of the forum threads. It's no different than setting up one domain, you just create a second one on the same server.
