Mahadevan, Didn't you read the reply I posted yesterday for the same question ? Here it is again, One way to block emails going to certain external domains is to create a separate SMTP connector for these address spaces, and by default "Reject messages from everyone". This will bounce back any mails sent to these domains. You can use a single SMTP connector to deny emails to multiple domains. HTH.
