Brian, I currently have this in main.cf: smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination and it allows all inbound mail from anywhere. Is the difference between "reject" and "reject_unauth_destination" that "reject" rejects everything and "reject_unauth_destination" only rejects mail for addresses we don't handle? Thanks, -Jon
