Default Redundant Mailboxes

Hello,

Ive been digging through the Zimbra Multi-Server Installation documentation trying to figure out an architechure that will work with my organization. What im looking for is a way for a single mailbox server to go down and still allow all users to continue using Zimbra off one one or more other servers--granted with slower performance.

From the looks of it though Zimbra assigns users to mailbox servers. And when that server goes down the users assigned to that server can no longer access their e-mail.

Is there a way to avoid this or is there something in the works? It just seems like a weak point in the whole Zimbra architechure (but still an amazing software package in the end).

We are planning on reproducing something similar where, if our main zimbra mailstore goes down, people can still access the last few days of mail using webmail from another server in another location. We are still trying to figure out details, though -- don't know how feasible it will be to achieve.

Have you looked at Zimbra Desktop?

Yes I have looked at Zimbra desktop and it seems to be an alternative for what I am looking for, but not close enough since a lot of the people in my organization use Outlook and only know Outlook it would be nice to have a sort of "Mailstore Proxy Cache" that users could allow Outlook to connect or use webmail and if the mailstore does go down they still have access to the last couple days of mail. That would really fix a lot of the issues were having here.

Besides, Zimbra Desktop won't allow new incoming mail to be seen or mail to be sent while the main mailstore is down. We are essentially trying to provide mail availability if our main location goes down by having a second zimbra server in another location that can store the last 2-3 days of mail and allow users to see new emails and send out emails.

(And clustering doesn't help, since if our main location goes down, the whole cluster would be unavailable)
