I'm trying to fix our flawed DNS record which lacks a reverse lookup. We do our own DNS with Microsoft DNS on NT 4 (Yes I know it's not a great DNS product). The intent here is to head off potential mail delivery problems, since some servers won't accept email if there is no reverse lookup. I read several docs (including http://www.stamey.nu/DNS/DNS-MSReverseLookups.asp) on how to create the record. Followed their directions then updated the server records and also stopped/started the MS DNS service. Yet when I run a test at dnsreport.com I not only keep flunking, but they ask for a DNS record using a name format which I was told was illegal, one which uses four octets instead of three. Here's the message from dnsreport, followed by my format (name only, does not show PTR contents). Can someone help?
ERROR: One of more of your mail server(s) have no reverse DNS (PTR) entries (if you see "Timeout" below, it may mean that your DNS servers did not respond fast enough). RFC1912 2.1 says you should have a reverse DNS for all your mail servers. It is strongly urged that you have them, as many mailservers will not accept mail from mailservers with no reverse DNS entry. The problem MX records are: 10.42.116.65.in-addr.arpa [No reverse DNS entry (rcode: 3 ancount: 0)] 42.116.65.in-addr.arpa Keith Purtell, Web/Network Administrator VantageMed Operations (Kansas City) Email: [EMAIL PROTECTED] CONFIDENTIALITY NOTICE: This email message, including any attachments, is for the sole use of the intended recipient(s) and may contain confidential and privileged information.
