I use a similar technique in my personal spam filter. All mail I send has my name in the "from:" RFC822 header. When I receive a bounce message, I look at the from: header of the bounced message and if it doesn't have my name, I know it's a bounce of something I didn't send. (Actually, I think I just do a string search of the entire bounce message for my name).

But I note that in the past two days, only 1 of the 900 spams addressed to my userid was a backscatter bounce. I know it used to be more.
