Not even close. You must first understand how Postfix smtpd(8) access restrictions work. See: http://www.postfix.org/SMTPD_ACCESS_README.html as a starting point. Since the text of your rejection implies that spam is the problem you're trying to address, you really need to understand more about spam and spammers, too. Here is a good overview: http://jimsun.linxnet.com/misc/postfix-anti-UCE.txt -- Offlist mail to this address is discarded unless "/dev/rob0" or "not-spam" is in Subject: header
