The rule description says "Envelope sender" which is what I was going by: 20_net_tests.cf:header NO_DNS_FOR_FROM eval:check_dns_sender() 20_net_tests.cf:describe NO_DNS_FOR_FROM Envelope sender has no MX or A DNS records I do block the envelope-from domain in postfix if it can't be resolved therefore I don't see any hits on that rule. http://www.postfix.org/postconf.5.html#reject_unknown_sender_domain Dave
