My contact is on hotmail. I can receive an e-mail from them. When I replay, it is returned to me with the following: This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: 

 [email protected]
   SMTP error from remote mail server after MAIL FROM:<[email protected]> SIZE=3240:

The error message clearly states your ISP has been blocked due to a bad reputation and to contact them. Contact them. This is not a Thunderbird issue.
