i did - but you still refuse to understand that *any* well implemented spam filter based on content also filters and rejects *pre queue* - nobody but you does accept *any* message and in many countries filter and delete spam *after* accept it from the sender even is not permitted by law *any* serious spam filter REJECTS at SMTP level because it is the only way the sender knows it was filtered while not be a backscatter because the *sending server* is generating the bounce with the rejct message of the final destination and if it was a professional spammer he will supress it and not read the reject message at all here you go: http://www.postfix.org/SMTPD_PROXY_README.html BTW: avoid to look answering yourself by quoting because you cut the poster you refer
