在过去的两天里，我在收件箱中看到了一些神秘的电子邮件“反弹”通知。 下面粘贴的是其中一个的原始内容。 请注意，我审查了我自己的个人信息。 所有这些消息的地址是[email protected]。
有问题的服务器是运行Apache，Caucho，Resin和一些其他与电子邮件无关的其他进程的Ubuntu 9.10盒子。 据我所知，它没有安装后缀（ which postfix什么都不返回）。
我可以采取哪些措施来正确诊断和解决问题？

垃圾邮件发送者的正常做法是使用其他人的电子邮件地址作为发件人。 这些地址以与目标地址相同的方式收获。 除了validation消息不是真的从你的系统发送，你无能为力。
如果消息是从你的系统发送的，那么你需要找出发送者是谁或做什么，并采取适当的行动。
如果消息正在通过您的系统中继，请确保中继function被立即禁用。
