There might be something you can do with DRBD's relatively new functions for maintaining remote synchronization of data. Or you might consider migrating your email to a leased server in a data center or a hosted solution where you're not as vulnerable to power outages (we're a tiny r&d company - we pay a few hundred a month for rackspace in a data center w/ multiple backbone connections, rock solid power, etc. - our email runs in a xen VM on top of a 2-node ha cluster). Short of a tornado (not too much of a problem in Boston), it's all pretty solid. Miles Fidelman -- In theory, there is no difference between theory and practice. In practice, there is. ....
