Specifically, this doesn't sound right (from spamitarium's POD
documentation):

=====
Moreover, headers which do not directly influence the email in any
functional way, nor are visible to the end-user in a standard
graphical MUA, are highly likely to contain information which 
spammers think will detract from normal statistical filtering. It
is therefore desireable to remove these elements, specifically 
X-headers, prior to filtering.  Spamitarium removes all invisible,
non-functional header lines.
=====

Is it foolishly naïve of me to think that bogofilter knows much more
about my personal mail history than some spammer, and can judge those
bogus headers as is?
