// The mail session is a replacement for the old 4.x MSG_Master object. It contains

// I'm starting this off as an empty interface and as people feel they need to
// add more information to it, they can. I think this is a better approach than 
// trying to port over the old MSG_Master in its entirety as that had a lot of
