I know that there are valid reasons (I have a friend who uses bcc's for all of her mass-emails-to-friends stuff), but isn't that the point of using a scoring system? I get WAY more undisclosed.recipients@ messages from spammers than I do from mailing lists (most of which either just don't have a To field, or include the list address, or some generic list name) or friends... anyway, just a suggestion. It's a "check" on a variety of other spam filters that I've seen, so I thought I'd mention it. -Chris _______________________________________________________________ Have big pipes?
