I want to test Zimbra NE 7.1 on multiple Ubuntu 10.04 servers.
We have 350 mailboxes and our current mail database is 150GB
We run a windows environment and have Active Directory.

What is the recommended setup? Medium or Large setup?

We would like to install it on multi servers.
- mysql on a seperate server.
- I guess seperate LDAP server is not needed (active directory)
- Is it possible to setup and webmail server in the DMZ?

I have the multiserver documentation. But it is unclear for me to find out how to install it on multiserver.

I hope someone can help me get on my way so we can test this!
