David, if I may be so presumptuous as to interpret, I think he means 
headers which are not visible to the recipient (i.e. not displayed in 
common mail clients) and also serve no functional purpose for routing or 
display.  Thus they are an opportunity for a spammer to put whatever 
text they want (presumably tested as hammy) in order to influence 
statistical filters and not impact their "visible" message.

Dmitry, whether spamitarium does it (or egrep as David suggested), or if 
it's built into bogofilter, it's still the same amount of work being 
done.  I'm perfectly happy not submitting bogofilter to feature creep 
and instead employing the *nix philosophy of building tools for a narrow 
purpose and stringing them together to do more complex tasks.
