Sorry Tom, bogofilter doesn't check the contents of X-Bogosity: when
registering messages.  There's no way to tell if the X-Bogosity line is
legit or spoofed.  With a low thresh_update value like 0.01, which
excludes messages scoring 0.01 and below or scoring 0.99 and above, the
need to correct is really, really low.
