Hi everyone,
I'm not sure if I'm missing something but I can't find out why my
body_checks doesn't catch all the backscatter I'm getting right now.
Oh yuck.
I've found that the best way to block backscatter is by using the
backscatter DNSRBL. Make sure you follow the instructions for setting
it up properly:

If used correctly it will only block DSNs from known backscatter sources.
