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 'sensor (e-mail address removed)'. Subject 'Fw: ',
Account: 'pop-server.new.rr.com', Server: 'smtp-server.new.rr.com', Protocol:
SMTP, Server Response: '550 Invalid recipient: <sensor>', Port: 25,
Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79

Unless it's a typo in your post, it looks like there's a space in the email
address...
'sensor (e-mail address removed)'
check to see if it's correct.
