Bright, I would take a few minutes and compose an email, i.e., thanking him for forwarding the phone email on to you. It's just a courtesy, but it also will open the door of communication just a wee bit.
Sometimes we tend to "over" think things and it creates more stinking thinking. Just be yourself. I know you would have sent an email to a friend, acknowledging the receipt of the forwarded email notification. I would do the same w/your h in this situation.
