Mail is store and forward, so your server doesn't know at time of
submitting the mail if it can be delievered. But you client will get a
bounce and therefore see that the delievery failed. Unfortunately
nearly no mailclient is able to notify the user in a understandable
way, but that a UI problem at the client side.
