當 hostname.domain.nl 位於“發件人:”電子郵件地址中時,電子郵件被拒絕
我有幾個 CentOS 5.3 系統,在所有這些系統上都有同樣的問題。當我向“root”(未指定域)發送電子郵件時,電子郵件被電子郵件提供商拒絕。有趣的是,我從郵件系統收到的電子郵件實際上是發送給同一使用者的,而我確實收到了該電子郵件。
這使得來自我的 cron 和星號的電子郵件首先被拒絕,然後我將它們作為附件從我的 mailerdeamon 獲取。
據我所知,這是因為“發件人”被歸類為“不存在”。我不明白“firewall.basjes.nl”主機名(= 連接到我的電纜調製解調器的系統)如何進入電子郵件驗證。
我的問題是:我必須更改什麼通用設置才能使所有程序(不僅僅是 cron 和星號)一次性使用?
我在下面放置了盡可能多的相關資訊。
(我用#$#替換了所有@以避免額外的垃圾郵件)
筆記:
- 我的 ISP 是 Ziggo,必須通過他們的傳出 smtp 中繼進行中繼。
- 我的郵件是通過Google應用程序託管的。
- 我有一個包含 LogFilesHobby#$#basjes.nl 的本地 /root/.forward

我找到了問題的真正原因。
此設置使所有使用者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
因為所有 cron 作業等都在 root 下執行,所以它們都保留了完整的主機名,然後執行到電子郵件提供商的檢查中。他們可能有這些檢查來減少垃圾郵件的負載。
解決方案:刪除 EXPOSED_USER(`root’)dnl
