Well, that's one of the problems I foresee, but also the fact that each 
email has a unique message ID, so I don't know if the backup server will 
pickup the changed messages ID's or not? I have been thinking of running 
a MySQL backed mail server, but have a feeling it will have a heavy 
impact on performance
