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 '',
Account: 'mail.fitebuilding.com', Server: 'mail.fitebuilding.com', Protocol:
SMTP, Server Response: '553 sorry, that domain isn't in my list of allowed
rcpthosts (#5.7.1)', Port: 25, Secure(SSL): No, Server Error: 553, Error

What about authentication?

Change the SMTP port to 587 and make sure: My Server Requires
Authentication is checked.

How do I set up/configure Outlook Express & Windows Mail for Comcast
email?

Make sure you have send authentication enabled.
Go to Tools, Accounts, select that account, Properties, Servers.
Enable the "My server requires authentication" option.
