If you are using Linux and sendmail, the solution is

1. edit /etc/mail/access
   add the following line
   lycos.co.kr<tab>  550 No spam allowed here
   korea.com<tab>    550 No spam allowed here

2. create access.db with the following command

   makemap hash access.db < access

2. restart sendmail
