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.
