讓 Postfix 將「驗證結果」標頭新增至發送至本機網域的本機發起郵件？

如果我透過sendmailSubmissionS 用戶端向我的虛擬帳戶（我的網域是 example.org）寫一封郵件，我收到的郵件如下所示：

如果我將其傳送給外部收件人，則會新增「驗證結果」。

如何讓 Postfix 將此標頭新增至發送至我的本地網域 (example.org) 的外寄郵件？米爾特是 Rspamd。

在我的“main.cf”中我有

# [...]

non_smtpd_milters = $smtpd_milters
milter_default_action = accept

在我的“master.cf”中我有

smtp             inet  n       -       n       -       -       smtpd
 -o milter_macro_daemon_name=VERIFYING

submissions      inet  n       -       n       -       -       smtpd
 -o syslog_name=postfix/smtps
 -o smtpd_tls_wrappermode=yes
 -o smtpd_relay_restrictions=permit_sasl_authenticated,reject
 -o milter_macro_daemon_name=ORIGINATING

# [...]

這是因為您的 OpenDMARC 配置已將 IgnoreAuthenticatedClients 設為 true 這將忽略來自您本地域的電子郵件。

看起來您正在使用帶有 authres_status 插件的 Roundcube Webmail 用戶端，對我來說，解決方法是編輯 authres_status.php 並檢測 DKIM 簽名是否包含我的網域，然後偽造狀態以傳遞 xD
