Can send but not receive email
I just recently setup my first mail box provided by Comcast. I am able to send email without a problem, however, when trying to send a reply to the comcast email, the server is unreachable. I am continuing to receive this message:
Sorry, we were unable to deliver your message to the following address.
Mail server for "americanlegionpost62.comcastbiz.net" unreachable for too long
I am really hoping this can be resolved, as I have emails waiting to go to this mail box for domain registration and the like.
