said by AlexComcast : I work at Comcast in the Anti-Abuse department, which manages the systems responsible for the message you're getting. Could you give me a little more information about the system you're sending from? The IP address would be very helpful. Have you ever been able to send messages via IPv6 to Comcast? Thank you.
Alex can you look into Neverwinter Online and War of Warcraft, when I have needed account verification emails I would not receive them in the time frame needed for both companies through Comcast email.
