Nigel,

Did you forget the example?  'Twould be best to put it in a zip file
and attach it.

Tokens in the "Subject", "To", and "From" lines get special treatment,
i.e. a prefix.  This allows bogofilter to score tokens in these lines
differently from the same word in the body of the message.  Bogofilter
can do its job without these lines (and their tokens).  As with all
things bayesian, extra tokens are helpful but the algorithm will work
even without the extras.

Summary:  Keep training!  Bogofilter will eventually recognize the
messages -- even lacking header lines.  I don't think there's anything I
can do to help.

Regards,

David
