http://www.postfix.org/postconf.5.html#check_sender_ns_access check_sender_ns_access type:table Search the specified access(5) database for the DNS servers for the MAIL FROM address, and execute the corresponding action. Note: a result of "OK" is not allowed for safety reasons. Instead, use DUNNO in order to exclude specific hosts from blacklists. This feature is available in Postfix 2.1 and later. Use this only for known-bad providers. Wietse
