You can use a restriction class to block mail for a specific envelope sender/recipient combination. The envelope addresses are what are logged by postfix, and may be different than what is in the From: and To: headers. http://www.postfix.org/RESTRICTION_CLASS_README.html If you must use the addresses listed in message headers, you will need a content filter such as SpamAssassin. -- Noel Jones
