摘要： The invention is directed to a system and method for determining if a “spam” message is originating from a messaging account by challenging a particular client's outbound email usage with a test that requires verification of content that is easily understood by a human being, not an automated computer program such as those used by “spammers.” If a limit on the number of recipients for outbound messages has been exceeded, a test is presented the next time a client attempts to send a message. The client must successfully answer the test within a relatively short period of time or else the ability to send messages will be disabled. Once disabled, the client can reinstate the ability to send messages by contacting a representative of the message system out of band, e.g., a telephone call to confirm legitimate outbound email use.

摘要翻译： 本发明涉及一种用于确定“垃圾邮件”消息是否源于消息账户的系统和方法，其通过对需要对人容易理解的内容进行验证的测试来挑战特定客户端的出站电子邮件使用，而不是 自动化计算机程序，例如“垃圾邮件发送者”使用的计算机程序。如果超出了出站邮件的收件人数量限制，则下次客户端尝试发送邮件时会显示一个测试。 客户端必须在相对较短的时间内成功应答测试，否则发送消息的能力将被禁用。 一旦禁用，客户端可以通过联系消息系统的代表（例如，呼叫来确认合法的出站电子邮件使用）来恢复发送消息的能力。
