I couldn't use my Windows Mail because it wouldn't send or receive, so
installed Windows Live Mail. I can receive mail OK, but when I try to
send, it gives this error message:
The message could not be sent because the server rejected the sender's
e-mail address. The sender's e-mail address was
Server Error: 530
Server Response: 530 authentication required - for help go to 'I'm
getting errors when trying to receive POP mail. What's wrong? - Mail'
Windows Live Mail Error ID: 0x800CCC78
Could anyone help me out with this?
