同一封电子邮件对于一个用户被评估为垃圾邮件，而对于另一个用户则被评估为常规邮件

Question

我有邮件服务器，安装了 spamassassin 来过滤垃圾邮件。

我面临的问题是，在 02h 第一个用户收到的电子邮件被视为垃圾邮件（并且是真正的垃圾邮件，已移至垃圾邮件文件夹，没关系）。

但在 07 点，另一位用户收到了同一封电子邮件，但并未将其视为垃圾邮件。

你能告诉我为什么会发生这种情况以及为什么第二封电子邮件不被视为垃圾邮件吗？

Answer 1

由于您提供的信息有限，否。

但是您有不同的个人用户偏好和可能的个人贝叶斯数据库吗？

您确实知道 SpamAssassin 添加带有触发规则的标头和产生的垃圾邮件分数，例如比较常规邮件：

X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on ...
X-Spam-Level: 
X-Spam-Status: No, score=-2.0 required=5.0 tests=BAYES_00,FREEMAIL_FROM,
    HTML_MESSAGE,RP_MATCHES_RCVD autolearn=ham version=3.3.1

垃圾邮件的冗长垃圾邮件报告：
