WOW! Internet is also a very stubborn ISP. In all my search I never found a verified port to use so I am assuming default for the time being. I will update if I find any new information.

Type: POP

Incoming:pop3.mail.wowway.com

Outgoing:smtp.mail.wowway.com

Incoming Port:110

Outgoing Port:587

Authentication: Requires only the username
