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
