without authentication? have you configured SASL auth? if no take down the server and go back to docs! I have auth. And this is restrictions I have: smtpd_recipient_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destination reject_unknown_recipient_domain It rejects user that's not authenticated but for authenticated users it can send for all 3 ips
