Hi, i need deploy zimbra for too clients (domains).
For that, i need that each client can add, delete and do other administrations tasks for just his domain.
For it, i have 2 options:
1. Purchase zimbra network edition
2. Deploy a email gateway solution and Install 1 VM per Domain in my Server. But i'm not sure if that Works properly.

I'm Correct.

Definitely do i need purchase?
