Стоит FreeBSD 9.0-RELEASE на которой dspam-3.9.0_2

dspam работает и никаких ошибок не выдаёт.
Обучен на большом количестве писем.

Но 100% писем, проходящих через него имеют такие хеадеры:

    X-DSPAM-Result: Innocent
    X-DSPAM-Processed: Fri Nov 30 00:45:12 2012
    X-DSPAM-Confidence: 0.9899
    X-DSPAM-Probability: 0.0000
    X-DSPAM-Signature: 50b7c958575206899212605

Как следствие весь спам валится в общую кучу.

Что я делаю не так? Крутил его уже во все стороны - результат один и тот же.

Если обучать заново - он спам-письма нормально учит как спам. Но результата всё равно никакого.
