My T is in private practice. My emails travel through the normal internet servers etc..etc... I am not concrrned about any interception of my emails, as they are quite dull, really. He occasionally has a printed copy in hand to discuss. Sometimes he has my email pulled up on his laptop screen suring my session. Not sure if those eventually get printed or not. It doesn't matter very much to me. He often encourages me to email, so it must not cause a time concern for him.
