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 'johndeerchic@xxxxxx'. Subject 'Fw: Fw:
We need this guy to talk for us]', Account: 'pop.yadtel.net', Server:
'smtpauth.yadtel.net', Protocol: SMTP, Server Response: '550 5.1.1
<johndeerchic@xxxxxx>: Recipient address rejected: User unknown in
virtual mailbox table', Port: 25, Secure(SSL): No, Server Error: 550, Error
Number: 0x800CCC79

The subject line mentions a receive problem, yet your error message is
for a send problem.

That error means you were sending while connected to a different
(non-Yadtel) Internet connection. Please describe those circumstances,
and whether you frequently need to send while away from home.
