    • A trust network database has any number of nodes, each node representing a user e-mail address. Links between nodes represent whether one user trusts another. Trust (that the recipient is trusted) is established when a sender sends an e-mail message to a recipient. The recipient is effectively placed on the white list for the sender. A legitimate e-mail address creates a strong trust link, otherwise it is weak. A spam count tracks by an amount of spam sent by each node. Outgoing e-mail messages are screened to make a determination that the sender trusts the recipient and that information is added to a local or remote trust network. Incoming e-mail messages are first screened to determine that the sender is legitimate. Then, the sender and recipient e-mail addresses are forwarded to the trust network to make a determination as to whether the recipient trusts the sender. A score (based upon number and type of links into or out of a node, the spam count for the node, etc.) for the sender is returned indicating whether or not the e-mail message is likely to be spam. An anti-spam engine is bypassed, used normally, or used aggressively based upon the score.
    • 信任网络数据库具有任意数量的节点,每个节点表示用户电子邮件地址。 节点之间的链接表示一个用户是否信任另一个用户。 当发件人向收件人发送电子邮件消息时,建立信任(收件人信任)。 收件人有效地放在发件人的白名单上。 一个合法的电子邮件地址创建一个强大的信任链接,否则它是弱的。 垃圾邮件数量跟踪每个节点发送的垃圾邮件数量。 筛选出外发电子邮件以确定发件人信任收件人,并将该信息添加到本地或远程信任网络。 首先对接收的电子邮件进行筛选,以确定发件人是否合法。 然后,将发送方和收件人电子邮件地址转发到信任网络,以确定收件人是否信任发件人。 返回发送方的分数(基于进入或退出节点的数量和类型,节点的垃圾邮件计数等),指示电子邮件消息是否可能是垃圾邮件。 基于分数,反垃圾邮件引擎被绕过,正常使用或积极使用。
