When I send from my comcast address and comcast website, the message goes through. However when I send from my thunderbird account it does not go through. Here is the message: What do I need to reset to get this particular email accepted for delivery. my other emails are going through.

Try sending to just one email address and see what happens.

Have you contacted Comcast to ask them to explain why they are rejecting the mail? Not the generic Spam error. What is the real reason they think it is spam. I am guessing it is because it is to more than one person.

Comcast have a very long history of opaque spam rules and they can not explain. Rules that only they use and only they can understand. At one point is two of their users clicked the spam button on their web site the sender automatically became a sender of spam. Regardless of the content.

Comcast is not rejecting the email. When I sent from comcast website to the email address, the message went through fine. Now I am back in my office today and the email address is going through fine. It has to be with mozilla on wifi remote or something very peculiar. Any other thoughts?
