当 hostname.domain.nl 位于“发件人：”电子邮件地址中时，电子邮件被拒绝

  • 772

我有几个 CentOS 5.3 系统，在所有这些系统上都有同样的问题。当我向“root”（未指定域）发送电子邮件时，电子邮件被电子邮件提供商拒绝。有趣的是，我从邮件系统收到的电子邮件实际上是发送给同一用户的，而我确实收到了该电子邮件。

这使得来自我的 cron 和星号的电子邮件首先被拒绝，然后我将它们作为附件从我的 mailerdeamon 获取。

据我所知，这是因为“发件人”被归类为“不存在”。我不明白“firewall.basjes.nl”主机名（= 连接到我的电缆调制解调器的系统）如何进入电子邮件验证。

我的问题是：我必须更改什么通用设置才能使所有程序（不仅仅是 cron 和星号）一次性使用？

我在下面放置了尽可能多的相关信息。

（我用#$#替换了所有@以避免额外的垃圾邮件）

笔记：

  • 我的 ISP 是 Ziggo，必须通过他们的传出 smtp 中继进行中继。
  • 我的邮件是通过谷歌应用程序托管的。
  • 我有一个包含 LogFilesHobby#$#basjes.nl 的本地 /root/.forward

创建此电子邮件的命令：

# mail -s TEST root

    我找到了问题的真正原因。

    此设置使所有用户都映射到我指定的域

    MASQUERADE_AS(`basjes.nl')dnl

    除了指定的那些

    EXPOSED_USER(`root')dnl

    因为所有 cron 作业等都在 root 下运行，所以它们都保留了完整的主机名，然后运行到电子邮件提供商的检查中。他们可能有这些检查来减少垃圾邮件的负载。

    解决方案：删除 EXPOSED_USER(`root')dnl
