I don't totally agree. The solution Mark Perkel explained is about the same in effect as greylisting but is much more simple to implement. The drawbacks of his solution are: -you cannot whitelist -you cannot control the minimum retry time -you must have more than one IP The good point is: -extremely simple to implement -very lightweight The comparison would be more like a strawberry cheesecake vs a chocolate cheesecake with strawberries on top. :D
