Likely the database isn't sufficient (lacks registrations of ham and spam)
or inaccessible to Postfix and bogofilter aborts early, omitting headers -
but that's only a symptom.

The real problem is that your way of integrating bogofilter does zero error
checking and will happily pretend success. There's a better way: bogofilter
ships with an integrating-with-postfix document (check the doc/) directory,
which please see. The most current version is in Subversion (not yet in a
release), see
<https://bogofilter.svn.sourceforge.net/svnroot/bogofilter/trunk/bogofilter/doc/integrating-with-postfix>

Alternatively, you can use maildrop <http://www.courier-mta.org/maildrop/>
to integrate bogofilter - that may be preferable if it's a single-user
install or you can otherwise benefit from adding a more sophisticated
filtering engine.
