You have permit_mynetworks in your setup somewhere. Right below it put: warn_if_reject check_sender_access hash:/etc/postfix/spoofstopper.map In /etc/postfix/spoofstopper.map yourdomain.com 554 From spoofed. Now watch your logs for the warnings and see if you really want to do this. You may be surprised by who sends as you, and you may be able to live with what you see. As an ISP, even a small one like we are, Cybertime can not afford to block mail with a spoofed from because I don't want to white list a huge number of places that do this for somewhat valid reasons. --Eric
