Assuming a directory with one message per file, you could run a script
something like:

   bogofilter -T -B $DIRECTORY | while read FN TYPE SCORE ; do
      case $TYPE in
          H)
            mv $FN Ham
          ;;
          S)
             mv $FN Spam
          ;;
          U)
             mv $FN Unsure
          ;;
      esac
   done

HTH,
