what you're asking for is something like active/active clustering or majority 
node clustering maybe with a replication product like DoubleTake...

Subject: [exchangelist] Redundant Exchange System

My management would like me to implement an Exchange system with some sort of 
server redundancy.
The idea would be two separate mail servers, one being a backup of the other.
Mail coming into server 1 would also get stored on server 2.
Both machines would be online all the time and maybe a replication process 
would run every 15 minutes that would synchronize the two.
In the event server 1 crashed, server2 would take over until server 1 could be 
fixed and got back on line.
From what I have read I don't think this functionality is built into Exchange I 
think I would need a third party product.
Does any one have any experience with such a set up.
