Change to: relay_recipient_maps = proxy:ldap:/postfix/etc/ldap_lookup.cf, hash:/etc/postfix/non-ldap-relay-recipients In that table: /etc/postfix/non-ldap-relay-recipients @example.edu no recipient validation @example.net no recipient validation ... Then, if possible: smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination, check_recipient_access hash:/etc/postfix/rav-lookup, ... /etc/postfix/rav-lookup: example.edu reject_unverified_recipient example.org reject_unverified_recipient ... Provided of course the nexthop relays for these domains do recipient validation at SMTP time. With some content filter configurations, you may need to mess around with one or more of: address_verify_default_transport address_verify_local_transport address_verify_relay_transport address_verify_relayhost address_verify_sender_dependent_relayhost_maps address_verify_transport_maps address_verify_virtual_transport -- Viktor.
