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.
