Comcast will not deliver email to private domain
I run an email server for my business. I have been receiving reports from others that emails were bouncing back, so I tested on my own personal comcast email address. Sure enough, I get no delivery, and then the temporary failures start rolling in later. I eventually get a permanent failure message. Checking my logs, comcast's mail servers are not even attempting to connect. I have no delivery problems for any other email services.
I'm hoping @ComcastCSAEmail can shed some light on what's going on or point me to someone who can see why this is getting blocked.
