You may have read in the news that "spam is under control", etc etc. Which is a misnomer. It should read: "Botnet spam is on the decline, but snowshoe spam and spear phishing is on the rise!". The botnet spam that greylisting was originally intended to deal with is becoming a lesser used vector, but you're probably seeing plenty of mail coming from places like romanian VIP hosting facilities that are plenty happy to rent out a /24 to a single machine for SMTP proxying.
