That's a pretty standard error. Did you confirm the email address?  Have you spoken to the recipient? Maybe he deleted his account or it is being blocked for some reason. That is not a TB error.  
Did you set up your TB account correctly? Have you ever sent successfully?

What is your question?
Marc ZCommented:
Also, did you set up your SMTP server correctly and are you connected to that servers network?
