Hello all...
I have a domain, www.xyz.com, hosted on the internet. I have a server accesable as office.xyz.com.
The server is the server for a whole office, and has 2 network cards.
The external address coresponds to office.xyz.com. The internal is part of a 10.x.y.0/24 net...
My provider at www.xyz.com hosts my email accoutns. (He provides virus scanning, and Spam controll)
I also run a local email on office.xyz.com, since I don't want local email sent over the internet...
Now to my question.
What should the domain name of the office.xyz.com be? What should the doamin name of the machine in the office be?
What is the "correct" way to set this up, (instead of the way I got it working now)?

Presumably, email to you at xyz.com goes to you@xyz.com. Hence the domain you own is xyz.com, whereas I could surf to www.xyz.com, which is a host. Provided that aspect is working to your satisfaction, the external naming is working fine and the terminology of domain and host [ie machine] is sorted. Now, do you want the host office.xyz.com to be accessible from outside? Does it provide any service for which I or your ISP or any outsider might need to access it by name? If so, it should be <hostname>.xyz.com, where office is valid as <hostname>. If you don't want it visible outside by name, don't give it an xyz.com hostname. Just call it office or something, either in the hosts files, or your internal DNS. Or invent an internal domain, which is not a recognised toplevel [.us, .uk .com .edu etc], and do your own DNS
