External users receive restricted comments

Tibor,

I transitioned an issue (which fires a post-function) and selected that the comment be an internal comment. My external user received that internal comment. How do I prevent the comment from sending IF it's supposed to be restricted to a specific group while still being able to send a state transition email to the external user?
