The hard part here is to detect false assumptions from users. For example, some will say that a mail is a spam while it is not, it is just a mailing list from a shop where they bought a product and clicked on the "I want to receive your mailings". The reverse is also possible (think phishing). As strange as it may sound, "un-spam-educated" users are often less accurate than automated spam filters. > Then for each user in the sample, you know how many mails are accepted and > how many are rejected, hence you can calculate stuff like what percentage > of all spam your system is rejecting. > > c > -- 010100100110010101101110011000010111010101100100 010000010110110001101100011000010111001001100100
