Postfix/OpenDKIM 未簽名 PHP 發送的電子郵件

我們為電子郵件安全/可驗證性安裝了 SPF、DKIM 和 DMARC 記錄。

當通過控制台或郵件客戶端（如 Outlook 或 Mac 的 Mail）發送時，它會完全處理並通過所有三個通道。

當通過 Zend Framework 1.12 的 SendMail 函式發送它失敗 (php)。

我們是否在某些時候錯過了配置 php 電子郵件的簽名？我們要查看什麼文件？還是必須有不同的安裝/附加組件？

我們在 Cent OS 6 上使用 OpenDKIM 和 Postfix

後綴 -n 結果：

這是我從 Port25 電子郵件檢查器得到的結果。除了 zend 時缺少 DKIM 之外，一切都是一樣的。

非 Zend 正常標頭： DKIM 簽名

當通過控制台或郵件客戶端（如 Outlook 或 Mac 的 Mail）發送時，它會完全處理並通過所有三個通道。

此行為是預期的，因為您將此配置放置在main.cf

smtpd_milters = inet:localhost:8891

當通過 Zend Framework 1.12 的 SendMail 函式發送它失敗 (php)。

這種行為也是意料之中的，因為您將此配置放置在main.cf

non_smtpd_milters =

解釋

預設情況下，OpenDKIM 通過milter與 postfix 結合使用。啟用/禁用 milter 應用程序由smtpd_milters和non_smtpd_milters參數控制。對於通過 smtpd 發送郵件的應用，對應參數為smtpd_milters，對於 sendmail，對應參數為non_smtpd_milters

解決方案

替換non_smtpd_milters =為

non_smtpd_milters = inet:localhost:8891
