For the past week I have been unable to send emails to a specific domain hosted at google. Emails are sent fine from other email accounts not on Comcast so the recipient address is valid. How can I troubleshoot this? It seems to be an issue between Comcast and Google. The comcast.net domain does appear on SORBS list also, could this be causing the issue?
I know the error says the recipient address could not be resolved, but why can I send from other email accounts not on Comcast?
Here is the copy of the error:
Generating server: CH1HUB01.CH1.COMCAST.NET

Just to add to the list, I am also having this problem, it has been days and still no resolution. When I send to a particular domain from my hosted account on Comcast it gets rejected, whether I send it through Outlook or Web mail. I can send to this domain successfully from any other account not hosted by Comcast.
Very frustrating that Comcast cannot resolve this.
