All mail enters postfix before it exits postfix. Filter your mail as it comes in to postfix with normal header/body checks. Milters and other external filters also generally work during input, not output. If you need to restrict these rules to "outgoing" mail only, use a separate postfix instance for submission. http://www.postfix.org/MULTI_INSTANCE_README.html -- Noel Jones
