Configuring exim4 for local network

I have a linux server running exim4 and is on a network of PC's running
email clients. When trying to send a message I'm getting the error
"relay not permitted". I understand why this happens but I can't find a
setting that works. The documentation has been informative but not
helpful to fix the problem. I'm sure this a very common setup and I'm
missing something. I have discovered that setting dc_relay_domains='*'
does make it work but I'm sure that isn't advisable. The network is
behind a router with the typical 192.168.0.* addressing. What is the
recomended setup for this arrangement? Any help would be appreciated.

For relaying control you just need (with sample values):

hostlist relay_from_hosts = 127.0.0.1:192.168.10.0/24

To actually deliver the messages, you don't say if you want to use a
"smart host" or just deliver, the later is the default configuration,
the former is done with something like:

smart_route:
driver = manualroute
transport = remote_smtp
route_list = * your-isp-smtp.server.com

that part goes in the routers section, Exim will try all the routes in
order.
