    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.
