You are using SPF, but are you using "-all" in SPF, and if you are using includes in your SPF records, do all those includes end with "-all" also? Currently, SPF has quite a wide implementation in the email ecosystem and "-all" should stop dead in its tracks almost all backscatter spam. It works for me. Regards, J.
