If you use the AWL, you have the list ready. Just scan the AWL DB for domain names. AWL has even more precise data than you want to gather. We could use it as well. If we assume we trust a new sender less than a sender we've already seen, then just score any message that has a sender not contained in the AWL DB (eg +1.0). -- Paweł Sasin "WIRTUALNA POLSKA" Spolka Akcyjna z siedziba w Gdansku przy ul.
