 Zimbra as a backup MX
We are currently a ZCS NE customer running one server at our primary hosting office, but would like to setup a backup MX in our secondary office. Is it possible, or permitted under the license, to use Zimbra as a backup MX in the second site? I did set up a basic postfix MX host but within a few hours I was getting spammed heavily. Part of the reason to go with Zimbra was so that the spam/AV features were bundled in and managed, if I have to configure up and maintain those features in the backup MX, then I've gained nothing really.
Here's how I'm envisioning the setup going.
Main site:
Primary MX host, all users and domains defined here.
Secondary site:
Backup MX VM, no users defined here, but all domains defined. Relay MTA set to the primary MX.
Would that be a valid configuration? Would the mail sit on the backup while the primary is down/unavailable as it should?
