Do you know what the latency delays are? For example, if you implemented greylisting and enforced a minimum 30 minute delay before you allowed them to get through the greylist, for what percentage of these messages would that 30 minute delay have been enough for them to show up on the BLs?

Have you incorporated tools like DCC or Razor into your methodology? Do you know how greylisting with a minimum delay time (e.g., 30 minutes) would effect DCC and/or Razor, in terms of their efficiency?
