Change VMWare Data Recovery 2.0 report mail

As I may have mentioned before VMWare Data Recovery is not my favorite backup solution. I'm pleased to report that VDR2.0 is a LOT better than 1.x ever was. Since upgrading, my backups haven't failed once. And it even has a built-in email reporting system. Unfortunately, this mail
