Then you need to read the RFC here: http://tools.ietf.org/html/rfc5782 For startes, only 127/8 is allowed in DNSxL replies. 127.0.0.1 is NOT allowed. You may also want to put a help box on the screen with the Posttfix documentation for reject_rbl_client, or a more average person digestible version of it. I assume this is a control panel for paying customers, who are usually not the most technical types. -- Stan
