Lets try another analogy set, ie  You run a gas station.  

open-relay:
	You give out free fuel to whoever turns up in a vehicle capable of
	accepting fuel from your bowser.

pop-before-smtp authentication:
	You require a valid corporate fleet card before handing out fuel.

full-anti-relay:
	You require payment before letting them near the bowser.

trusted-hosts or IP-based access lists:
	If their numberplate is in a certain range, give them free fuel.

> How about commercial anonymous re-mailers? 

Ah, this would be:

	You give out free fuel on sighting, but not verifying, a corporate
	fleet card, and give them a new car.
