I see the point. Our (company using Exim installation I talk about) policy is to accept mail even from those hosts that do not implement SPF/DKIM/whatever else, even in cases when mail is sent from an IP not verified by SPF and so on - we have too many legitimate mail that doesn't pass those checks. So currently I have 500 to 1000 of backscatter mail sitting in mail queue, since it can't be delivered to forged sender of spam sent to non-existing local addresses. Are there efficient ideas to reduce that number? I would appreciate any advice. Thanks.
