同一封电子邮件对于一个用户来说被评估为垃圾邮件，而对于另一个用户来说则被评估为普通邮件

我有邮件服务器，安装了 spamassassin 来过滤垃圾邮件。

我遇到的问题是，在 02h 时第一个用户收到的电子邮件被视为垃圾邮件（并且它是真正的垃圾邮件，被移至垃圾邮件文件夹，没问题）。

但 07 点，另一个用户收到了同样的电子邮件，但它并未被视为垃圾邮件。

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没有被视为垃圾邮件吗？

根据您提供的信息有限，答案是“否”。

但是您有不同的个人用户偏好和可能不同的个人贝叶斯数据库？

您确实知道 SpamAssassin 会添加带有触发的规则的标头以及由此产生的垃圾邮件分数，例如比较常规消息：

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

对于垃圾邮件的冗长的垃圾邮件报告：
