I really must get a Real Life if this is how I spend Friday evening on the Fourth of July weekend... I don't think the first name in an FQDN must be a domain name; I think it can also be a host. For example, www.ebay.com is a FQDN, but the www refers to a host. Similarly, in an internal LAN, you can refer to server.domainname, and that is a FQDN. So mail.salemradiology.com could refer to a subdomain or to a record in the domain (such as an MX record). Unless I give you context, you have no way of telling which.
Ah, well, I'm sorry to drag you all into this. Thank you very much, and may this be the best of 4ths for you all.
