Why are emails to Comcast users being blocked?
Comcast will not reveal why, but occasionally it detects a triggering event to block emails from our servers (and many other servers in the internet world). Supposedly, it sees emails being forwarded from your own domain hosting account to your own comcast.net mailbox. In the case that this forwarded message is a spam email, Comcast does not recognize that your domain hosting account (our servers) are NOT the originator of this spam- Comcast thinks we are the source and then blocks us. When this occurs, we’re usually aware, but it doesn’t hurt to let us know that you have found your account to be blocked- we petition comcast to remove us from their blacklist.
