Well, I think everyone's got the same point, but Sandy probably says it best. We have a single MX record for the host "mail" in that zone. We do not have an MX record for a root host (one that does not have a name) for the same zone. So when we do a lookup on the mail MX record, we see it. However, apparently DNS Report only looks for the root record, which doesn't exist in this case. Sandy calls this a "restriction", I would call it a bug.
I am not (not even close to being) a DNS expert, but some of the other replies posted do not fit with my understanding of the DNS setup. The host "mail" is not a subdomain, it's a host. And the record that has 'no name' is a "root" host, but it's still a host, and not a subdomain. There is only one domain/zone, and that's salemradiology.com. The rest are records for hosts within that domain. At leat, I always considered hosts and subdomains to be different animals. So I expected that DNS Report would look through all the records in this zone, looking for any MX records, and identifying those as mail servers; instead, it only looked for a "root" host mail server. It's kind of like assuming that a web site name must start with a "www."; that's the common usage, but it is not required. If I'm wrong in this understand, I'd love to hear it. And thanks for all of the replies; all let our clients know that the best way to fix this is to simply add that root MX record.
