I'm confused as to which way this reads, but still... To make sure you don't accept messages for non-existent addresses in domains you handle, in the RCPT ACL you need require verify = recipient That will run the recipient through your routers and make sure a significant delivery will happen. To ensure the inbound sending domains are valid domains, in the MAIL ACL you need require verify = sender That will make sure that the remote domain exists.
