How to disable postfix address verification

Question

I'm doing some spam/botnet research and need to accept all email that my mail server receives. I've set postfix up, but I can't seem to figure out how to disable the sender address verification function. During my initial tests (spoofing mail source as [email protected]), I discovered postfix checks with the sender's mail server to verify the user exists (which it doesn't in my test case). As a result, the test message fails. Any ideas?

Got it... Paste this in /etc/postfix/main.cf

smtpd_restriction_classes = verify_sender
verify_sender = permit
