尽管发件人已列入白名单，SpamAssassin 仍将合法电子邮件发送到垃圾邮件箱

我无论如何也想不通为什么来自“白名单”发件人的电子邮件仍然会从 SpamAssassin 获得很高的分数，但却无法投递。

Sendmail 正在做什么

答案1

所以分数是 -107.9（负一百零七点九）。这非常非常，非常低，肯定低于垃圾邮件的 5.0 阈值。我猜这些星号是你加的。

答案2

找出邮件无法送达的原因的方法是检查邮件在经过 MTA、反垃圾邮件、防病毒等程序时的整个生命周期，而不是只关注反垃圾邮件方面。这涉及/var/log/maillog从邮件的接收到最终送达的整个过程。

原作者的邮件日志显示，Sendmail 已收到邮件 q3PHqPpR019683，然后将其传递给spamdSpamAssassin 进行评分。SpamAssassin 为其分配了一个非常低的分数，这对于白名单发件人来说是意料之中的。然后，该邮件返回到 Sendmail 进行进一步处理。Sendmail 随后成功将邮件（带有“stat=Sent”）交给 shell 脚本：。从 Sendmail（和 SpamAssassin）的角度来看，该邮件已成功接受、评分并移交给流程的下一阶段，因此问题不在于 SpamAssassin。to="|/etc/mail/jprocess [email protected]"

原始发件人对/etc/mail/jprocess脚本的检查表明，在将邮件传递给 MDA 之前，脚本处理标记邮件的方式可能存在问题。修改该脚本后，测试邮件便可成功传递。

请注意，jprocess 脚本似乎是非标准的。更“可接受”的方法是使用 Amavis-ng 或 Sendmail 邮件过滤器之类的东西。OP 可能想要调查这些选项。
