What am I missing in Postfix setup?

When sending from one client on the network to anothre client on the 
same network, Postfix sends the following error:

Final-Recipient: rfc822; sewrenn at wrennest.com
Action: failed
Status: 5.0.0
Diagnostic-Code: X-Postfix; Name service error for name=localhost 
type=A: Host
     not found

When receiving mail from the Internet, /var/log/mail spits out the 
following:

The common thread here is localhost. What am I missing?

<rant>
Is there some where a simple check list for how to set up Postfix as a 
mail server to handle a small network? The last time I did this (five 
years ago) I went through the same sort of nonsense.
