The number of compromised customer hosts lately have been increasing. It's more likely that your spammers are using normal well configured MTAs (postfix/exim/etc) on compromised servers which are going to eventually get through the greylist. I do agree though -- there are too many getting whitelisted lately. If anyone has recommended greyscanner tweaks I'd love to hear them.
