In this method (full clustering), you have to make sure the software you use also mirrors registries, since that's where aliases, lists, and domain information are stored. And since you're mirroring registries anyway, you don't have to use ODBC. As I've written elsewhere, MSCS, DoubleTake, and Legato will all do this. Then you can put a load balancer (F5 is my pref) in front of it all. But this isn't the only way, by far. I've put in full clusters using MSCS, but I prefer the load-balanced farm. There's nothing so tough about it. You spread your users across a couple of servers and use Imail Peer Servers for routing. The overall paradigm shift for this model is cosmetic: you tell your users that their POP3 server is mail9.yourdomain.com, and you either have a gateway web portal that redirects the user's browser based on login name, or just send a customer right to their webmail at www9.yourdomain.com.
