You're going to need something in front of the two servers to abstract
the connections (another poster recommended ultramonkey) if you want
them both to be serviced by the same IP address. My suggestion was to
use active/standby, where the standby doesn't "up" its mail IP unless it
detects the primary is dead, typically through some kind of heartbeat;
not separate clients across the two servers.
