They aren't URLs. The incoming setting for me is POP-server.hvc.rr.com and the outgoing setting is SMPT-server.hvc.rr.com. I had originally used those settings but, for reasons which I have forgotten, had to speak with Time Warner tech support several years ago. The rep told me that I needed to change upper case to lower. When I did that, the connection failed. I changed it back to upper case and it has worked ever since.
