Okay, I just got a new computer and upgraded to Windows Vista, and I decided
to use Windows mail in lieu of Mozilla Thunderbird and whatnot. I have put
in the correct addresses for my incoming and outgoing email. I am currently
receiving email; however, I am unable to send email. I keep getting an error
message that states:

The message could not be sent. The authentication setting might not be
correct for your outgoing e-mail [SMTP] server. For help solving this
problem, go to Help, search for "Troubleshoot Windows Mail", and read the
"I'm having problems sending e-mail" section. If you need help determining
the proper server settings, please contact your e-mail service provider.

The rejected e-mail address was '. Subject 'Test', Account:
'pop.west.cox.net', Server: 'smtp.west.cox.net', Protocol: SMTP, Server
Response: '550 5.1.0 Your email could not be delivered at this time. We
apologize for the inconvenience. If you are using a new Cox.net email
account, please try again in 15 minutes. If you are not using a new email
account, visit http://support.cox.com for additional assistance in correcting
this issue.', Port: 25, Secure(SSL): No, Server Error: 550, Error Number:
0x800CCC78

I've already contacted Cox, and their analyst appeared to be as baffled as I
was, and we tried various settings with no luck. Anyone have any ideas on
what the problem could be? I'm accessing email and the Internet from a
wireless network set up in my home, so my computer is fairly close to the
router (I could understand this message if I was accessing Wi-Fi somewhere
else). I REALLY need to be able to send email without using webmail. Any
assistance would be greatly appreciated
