What "legitimate business purposes" necessitate leaving SMTP relays open to the world?
How about running a commercial email gateway?
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. --==-- Bruce. Peregrinus expectavi pedes meos in cymbalis est.
