You really need to be reading the documentation. There are several ways to
selectively enable relaying - all are described in the docs or in the
default config file.

Here are 2 things to start with:

1. Put the IP address or range you want to enable for relay in the
relay_from_hosts hostlist - that's the IPs of the sending hosts (easy)

or

2. Enable SMTP authentication for the group of users you want to be able
to relay (more difficult, especially if you don't understand the concepts)
