In the last couple of weeks when I send out an email the receiving party gets my message with .com at the end of the email. So when they attempt to reply they get a "can't deliver" response. Somewhere in the system the .net is superceded with .com.
Your thoughts, please.
Try sending yourself an email at some other, non-Comcast, account you have like Gmail, or Yahoo or something. Does it go through OK, and does it show .net or .com as the top level domain?
