I can receive and send emails from a second email address.  Lately when I have sent out emails the second email appears randomly in my reply to box when I have not chosen it. I would like to remove that second email address from my reply to box.  I have tried to delete it in the reply  to address under options but it still there.  I need to receive emails for this address but would like to take it out of send from category.  How can I do that?
