If you use the "simple" content filter approach as described in http://www.postfix.org/FILTER_README.html with Postfix 2.3 and later, use: /etc/postfix/master.cf: filter unix - n n - 10 pipe null_sender= flags=Rq user=filter argv=/path/to/script -f ${sender} -- ${recipient} This prevents the null sender from being replaced.
