Putting a greylist in action like this has nearly cut our spam to our abuse@ address to just noise as compared to before when it was overwhelming. We can't filter on that address since legitimate complaints may contain stuff that scores high. You do have to be very careful with whitelisting certain places or you could end up with mail you can't deliver. For example, many sites use a sender verification call back, and if you defer that, then the outbound mail doesn't go through to that site. The next attempt to deliver it may contact a different server, etc. --Apple-Mail-33--125582665--
