License wise, you may just wish to install the Community Edition on that box.

Domains only on the backup MX? How do you handle the backscatter between the primary MX and the backup MX when the backup MX accepts an email for nonexistentuser@legitimatedomain.com?

All of the Postfix documentation preaches never to accept delivery of any email except for valid recipients.

Is the backup MX an LDAP slave? Is it legal from a Zimbra license standpoint for a CE Zimbra install to be a slave to an NE Zimbra install?

Thanks!
