On my personal corpus, which is around 10k ham and 700 spam now, I'm
actually seeing the full headers causing harm, not benefit. Analyzing
it some, it looks like the problem is that _most_ of my spam is delivered
directly to me, while most ham is via mailing lists. This means that the
occasional spam via mailing lists nearly always gets fn'd.
More on that later - I'm currently processing the scheme-deathmatch.
