Well, only very stupid bots don't behave correctly and start sending before they get the correct greeting. So in my experience greylisting still is very effective, especially if you use it in conjunction with using whitelists of known good mailservers like dnswl.org and not greylisting when SPF matches. This allows of fast delivery of almost all legit emails.
