The above does not show the usual SMTP reply code 
which Yahoo generally uses in such cases.  The 
connection is being closed from Yahoo's end.  I 
suggest contacting Yahoo as you cannot send mail 
to them.  The short answer is that this is not a network or SMTP issue.

The long answer is that you may not be following 
the usual practices for that mail server.  As a 
starting point, you can go through the answers at 
That doesn't document most of the usual practices.
