I think you will find that people who want to reject the spam but don't want to accidentally reject real mail will sometimes use 45x instead of 55x error codes. I know when i was rejecting spam at the SMTP layer I first started rejecting with 45x and watched my logs for those pesky false positives. there might be some thought about punish the disk space of those that are trying to deliver the spam to you ... - Jared On Mon, Dec 01, 2003 at 10:10:43AM -0800, Randy Bush wrote:
