As always it would be helpful if you provided Postfix logging of these rejections so we can see what is actually happening. At this point we don't know if it's the postscreen bot detection that's causing the rejections, or the dnsbls you have configured in postscreen that are causing the rejections. The proper fix to your problem may be different depending on the which is causing the rejections. -- Stan
