This section contains four sample configurations. The first example, Example 2-2 illustrates the use of rewrite rules. The second example, Example 2-3, illustrates a configuration which may be used on a satellite cluster or node which routes all non-local mail to a hub. The third example, Example 2-4, shows a sample configuration for a site connected to the Internet. And the final example, Example 2-5, demonstrates the handling of a local network in which only one of the machines is running PMDF and the other machines are networked via DECnet.
