Avermont, I'm with newmama and cutter on this one. Say nothing, you're not a messaging service. I still get mail at my place which I write "no longer at this address". If he can't get his act together to change contact details then that's his prob. Not to mention if he just went to the doctor you would have thought the first thing he would have changed was all his contact details - especially if the norm is for the doctor to call and give the results over the phone.
