Can not send message

[LL]

Does anyone have a solution to the problem listed below? Please help!


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 'Re:

'smtp.comcast.net', Protocol: SMTP, Server Response: '550 5.1.0
Authentication required', Port: 25, Secure(SSL): No, Server Error: 550, Error

Comcast made some changes in their email settings. Follow these steps:

Note that the outgoing server now requires port 587 rather than port 25.
Also, "My server requires authentication" must be checked.
