I'm a computer security consultant. I have a friend that runs a large ISP and tracks spammers for a living. It is trivial to spoof those headers. If you're relying on headers then you're getting bad information...guaranteed.

I've used headers to track and kill sources of spam - so don't tell me it can't be done, becuase I know otherwise.
