I recently asked the vendor of an email filtering product about
greylisting. They don't have any intention of using it because of
software like "123hiddensender" - a bulk email sender which "retries"
delivery. The reason for not supporting "greylisting" was to avoid a
possible DDOS where the spammer just keeps trying.
