I don’t know of a back-door way to do this. Not saying there isn’t one, but it’s not something that’s usually done. Have you thought about getting a separate url and email set up and just mail forwarding that to your usual box? That’s the only fix I know. If your domain hosting company doesn’t have good support to ask if there’s another way to handle it, call BlueHost or GoDaddy. Both have excellent tech support and will tell you if it’s feasible.
