Dear bogofilter maintainers,

May I ask again to make a config option "do not process invisible 
headers"? It is so obvious that ommiting invisible headers improves 
bogofilter accuracy in spite of what theory says. Why do we need another 
tool like spamitarium just to remove additional work instead of not 
doing that work at all?
