nah, use a load balanced cluster. bookmatch a pair of alphas or 2550 dells with common storage. build for mscs (m$ cluster service). search m$'s kb for details on mscs. if one box fails the other picks up immediately

Quick question: I was wondering what would be the best way to be prepared for disaster recovery. For instance right now we have one Imail server and a backup spooler server. The Imail server is the 10 mx record and the spooler is the 20 mx record. Now if the main Imail server crashes then our users will not be able to authenticate, only their incoming mail will be spooled on the other server until we can get a the crashed server up again. Can I have two Imail servers where if one completely went down the other would take over authenticating and operating as if nothing happened? If so what would be the most efficient way to set this up? Would I just setup two servers the exact same way (one with the primary mx ip and the other with the secondary mx ip) and everytime I get a new user just add it two both servers?

Any help would be appreciated.

Thanks,
