Thank you Ansgar, Does it mean I cannot use this method to block un desirable mails this way? At first I tried using the method explained on http://www.cyberciti.biz/faq/howto-blacklist-reject-sender-email-address/ but this could not allow postfix to restart. That is why I resort to this. Is there another way around this?
