I'm using the NE eval'ing for a fairly serious group and expecting to pay for a bit more data security than "back up our backups"

. It's always good advice and yes, I will certainly do so if we decide to buy in. That option should probably be part of the upgrade script, if a zimbra employee and the consensus of experienced users indicate that it should be done, no?
So far, zimbra does seem to be a good fit and I really like the way the system is moving, but the complexity and amount of time it's taken to become even marginally comfortable with the gotchas and "lore of the zimbra way" is a bit disconcerting. However, I realize I'm reporting an unsupported installation so I'm grateful that you're talking to me at all.
Tomorrow, it goes on a ubuntu 606 server.
