雅虎的電子郵件暫時被暫停，而雅虎根本不在乎

我的郵件隊列中有 4000 封等待發送給雅虎的電子郵件，如下所示：

這個錯誤絕不是暫時的！我已經有很多年了，只是雅虎遇到了問題，這是我的郵件伺服器向 gmail 發送電子郵件時的日誌範例：

其他所有電子郵件服務都可以使用我的電子郵件，這只是雅虎。

這是雅虎的回答：

他們根本不在乎。我已經註冊了雅虎投訴回饋循環，沒有收到任何投訴。

我還檢查了 mxtoolbox.com，絕對沒有報告任何問題，並且所有檢查都通過了。我有 DKIM、DMARC 和 SPF，它們都“通過”。電子郵件使用正確的 SSL 加密。

有人知道如何解決這個問題嗎？這對我和我的使用者來說真的很煩人，他們必須等待 24 小時才能從我的電子郵件伺服器接收他們的電子郵件。

您需要為所有 Yahoo 域配置 Postfix 的傳出速率限制，因為顯然 Yahoo 不喜歡您的速度/並發級別，並且您的 MTA 總是因此觸發某種類型的反垃圾郵件防禦機制。

看看這個作者遇到同樣問題的部落格文章，它可能會有所幫助：

https://www.stevejenkins.com/blog/2012/08/how-to-postfix-configuration-to-reduce-yahoo-deferrals-using-transport-maps/

可以在這裡找到更簡單的描述：https ://wiki.deimos.fr/Postfix:_limit_outgoing_mail_throttling.html#Limit_by_domain

如果速率限制沒有像預期的那樣起作用，您還有兩個選擇：要麼完全忘記向 Yahoo 發送電子郵件，要麼使用在 Yahoo 有良好信譽的商業郵件傳遞提供商來完成該任務。
