Over the last few days, my personal e-mail address has been being pounded by backscatter. There is apparently a spam operation under way that is using my e-mail address as the fake From:. As a result, I get all of the bounces from mail servers that are misconfigured and don't reject undeliverable mail up front during the SMTP connection.

Does anybody have any recommendations on how I can significantly cut down on the amount of backscatter I receive? Would SPF really help me much? I'm inclined to think not, since these mail servers are already misconfigured and sending out rejects as e-mails instead of as SMTP codes.

I need a solution that can plug into a Postfix/SpamAssassion setup.

Any pointers would be greatly appreciated. I'm being buried alive over here. And since I'm currently trying to work with banks, real estate agents, and so forth, I really don't want to miss any important mail.
