For an IP you need to lookup the PTR in reverse notation (1.0.0.127.in-addr.arpa) vs an A record which is name to IP. PTR is IP to Name.
Oops... Hit reply rather than reply-all... Resending via reply-all... _______ If I understand correctly, you're asking about this... dig 1.0.0.127.in-addr.arpa which returns the same on machines where qpsmtpd-async is working and the one machine where it's broken... ;; AUTHORITY SECTION: 127.in-addr.arpa. 604800 IN SOA localhost. root.localhost. 1 604800 86400 2419200 604800 If you're referring to something else, give me an exact command + what I should be looking for. Thanks.
