"Server Admin" is an error. The article refers to the Server application.

OK, so if the Advanced Administration guide doesn't document how I can do this with 10.8.2/server 2.2 how can I do it?

Just read "Server" for "Server Admin."

So in the advanced admin guide at this page http://help.apple.com/advancedserveradmin/mac/10.8/#apdB3F8B86B-1839-4692-85FD-0 07FC7222B78
I can't do what it directs with the server app (replace server admin with server)?
There is no Settings -> Relay?

They've removed that setting from the GUI. By default, Postfix is configured to accept mail only from the local subnet. If that's what you want it to do, you don't have to change anything. Otherwise, you'll have to edit the directives in the section "TRUST AND RELAY CONTROL" in the file

As Linc noted above, you don't need to do anything special to prevent your system from being an open relay.
If you're a belt-and-suspenders guy, you can double-check your installation with this nifty tool from MXToolbox: http://www.mxtoolbox.com/diagnostic.aspx. Just type your server's address into the box and hit "Test Email Server". It'll run for a few moments and check a few settings on your machine. OS X Server should pass all tests with a default installation.
This tool is also handy for periodically checking to make sure your IP address isn't on a realtime blacklist (RBL).

MXToolbox was a really helpful confirmation step - thanks.
