Well, I wish you the best of luck because you're going to need it.  kornet 
is a Korea operation that sends tons of spam.  I actually got a reply back 
from them one time that told me in very definite terms to stop bothering 
them.

kornet.com owns a series of ip's.  Just put the following line in 
/etc/mail/access (assuming you're using sendmail)...

204.228.229		DISCARD

and then do a 

makemap hash access < access

There is no need to restart sendmail.  This will result in sendmail
discarding all further email from any of their ip's.
