This is totally bullshit IMHO. You can trace the any e-mail back to the
original SMTP server using the headers. Fake headers are usually easy to
spot. When in doubt I use telnet to get into the SMPTP servers one at a
time, up the sendmail stream, and then e-mail myself to see how a real
header from that server looks like.
Yes, you can 'try' to trace these clowns with the headers, but more often
than not it gets you nowhere. I have seen too many where the originating
host is on a subnet that is firewalled, the host does not run an smtp daemon,
or the host 'conveniently' claims all responses are to user unknown. And with
so many picking arbitrary hosts as mailer relays, and then disappearing,
where do you go? I have also seen too many using fictitious domain names,
as well as using the private address spaces to further compound the problems.
