You configured address verification. http://www.postfix.org/ADDRESS_VERIFICATION_README.html Don't specify address_verify_transport_maps unless the verification probes must use a route different from normal deliveries. http://www.postfix.org/ADDRESS_VERIFICATION_README.html#probe_routing The "loops back to myself" message occurs when postfix is greeted with its own HELO hostname. If normal mail deliveries are successful, then don't specify custom routing for the verification probes. If you need more help, please see: http://www.postfix.org/DEBUG_README.html#mail -- Noel Jones
