垃圾邮件对电子邮件用户来说是一个日益严重的问题。许多反垃圾邮件方案已经被提出和部署，但这个问题还没有得到很好的解决。其中一种方案是挑战-响应，其中挑战是强加给电子邮件发件人的。然而，这样的方案给用户带来了新的问题，例如，服务延迟和拒绝服务攻击。在本文中，我们介绍了避免这些问题的前挑战计划。它假设每个用户都有一个由用户自己定义并与他/她的电子邮件地址相关联的挑战，以这种方式，电子邮件发送者可以在第一次联系中发送电子邮件之前同时检索新接收者的电子邮件地址和挑战。采用了一些新的机制，以达到对垃圾邮件的安全性和方便电子邮件用户之间的良好平衡。
Spamturns out to be an increasingly serious problem to email users. A number of anti-spam schemes have been proposed and deployed, but the problem has yet been well addressed. One of those schemes is challenge-response, in which a challenge is imposed on an email sender. However, such a scheme introduces new problems for the users, e.g., delay of service and denial of service attacks. In this paper, we introduce apre-challengescheme that avoids those problems. It assumes each user has a challenge that is defined by the user himself/herself and associated with his/her email address, in such a way that an email sender can simultaneously retrieve a new receiver’s email address and challenge before sending an email in the first contact. Some new mechanisms are employed to reach a good balance between security against spam and convenience to email users.
