Documentation for hosting setup
I see that you support multi-domain configurations. That's fantastic! We currently use a commercial webmail solution (and several local major modifications as well as our own provisioning system) on 2 load balanced machines for webmail, 2 load balanced machines for imap, 2 load balanced machines for smtp, and 2 load balanced machines for ldap, all behind two (for failover) load balancers using heartbeat and ldirectord. I'm investigating whether we could use and modify zimbra to suit our needs. Do you have any documentation on configuring zimbra in a hosting environment? I'm still looking through the docs and architecture docs, so maybe I haven't stumbled onto it yet.
Nice product, very fancy!
