These days, the sensible approach seems to be that *no-one* can relay *unless* they can also authenticate. Sometimes, though, you have a DMZ-style setup where you want to have the Courier system act as the externally aware gateway system, such that all mail generated inside the network is relayed through via Courier. Then you'd set up the relay IP address range, and go with that. This is how many dial-in ISPs *used* to work (and many may still do), until they realized that the extra authentication didn't hurt too much and, in these days of poorly-protected wireless connections, it avoids parasites leeching onto the "safe" network and using the mail resources. In other words, if you don't know that you want to permit arbitrary IP's to relay, don't permit them, and use the authenticated-users method (which is the default with Courier).
