I was using my ISP's POP3 email account with Windows Live Mail on Windows Vista. Today I upgraded to Windows 7 using a upgrade disk but using a custom install. Before upgrading I exported my email account settings and messages. When I upgraded I downloaded Windows Live Mail 2011 and imported my account and emails.
Now I can send emails from the account, however when I attemt to send a message to the account I receive a mail delivery error (in this case in Gmail).
Delivery to the following recipient failed permanently:
Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550-5.1.1 The email account that you tried to reach does not exist. Please try 550-5.1.1 double-checking the recipient's email address for typos or 550-5.1.1 unnecessary spaces. Learn more at 550 5.1.1 http://mail.Google.com/support/bin/answer.py?answer=6596 14si1022989ibb.65 (state 14).
I know that I have the email address spelled correctly because I tried replying to a email sent from my account.
Please advise as I do not understand why there would be such problems as I have not made any changes to my email account on the server.
