as I read this (thanks for the link) there is no real solution to the
problem. Under "Reducing the problem" it says:
Checking bounce recipients
Mail servers sending email bounce messages can use a range of measures
to judge whether a return address has been forged.
Which "range of measures" is this referring to?!
It is possible to mitigate the backscatter problem. There are
various heuristics used. RFC 5321 discusses about the unwanted
messages problem. Instead of trying to fix the backscatter problem
it would be easier to find out what configuration options could be useful.
