I disagree here.

If only a few of us would use greylisting no spammer would think about
implementing queues.
But if the majority would use it and they (the spammers) implement
queues, it could end in a disaster for them. Or how would you call
a queue with millions of messages waiting?
And now for the warriors among us: At that point you could play with
the time window perhaps using random shifts to at least knock them out.
I'm using mimedefang as my 'aircraft-carrier' for such games. ;)
You are able to react very fast with that tool if the situation
would change!
