Were you sending from home when you got that error message?
Cox does not support using their SMTP server when away from home.

This is the error message I get:
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 '(e-mail address removed)'. Subject 'test',
Account: 'pop.east.cox.net', Server: 'smtp.east.cox.net', Protocol:
SMTP,
Server Response: '550 5.1.1 <
[email protected]> relaying not allowed',
Port:
25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79
Thanks for any help.
