由於 DMARC 失敗，來自 Teams 的郵件轉發到 Gmail 被標記為垃圾郵件
當我在 Microsoft Teams 中編寫聊天消息時，接收者在 Teams 中離線時會在其 Office 365 帳戶 (receiver@htlvb.at) 上收到電子郵件通知。收件人進行了設置，以便將她的所有郵件轉發到她的個人 Gmail 帳戶 (receiver@gmail.com)。對於發送到receiver@htlvb.at 的普通郵件，這可以按預期工作。但所有 Teams 通知都被標記為垃圾郵件。Google表示 DMARC 失敗（見下文）。
我們有一個帶有以下 TXT 記錄的自定義 DNS 伺服器：
Google 顯示收到的郵件的以下詳細資訊：
以及以下消息來源：

我會假設它的微軟錯誤打破了他們的簽名。標題清楚地表明簽名在轉發之前是好的，然後在Google收到時被破壞。檢查簽名的標題，一個突出：

請檢查
X-MS-Exchange-SenderADCheck送出時郵件上的值（例如，在非轉發收件人收到的類似郵件中）。如果我是正確的，並且 Microsoft 在轉發時更改了該特定標頭，這會在將其移交給 Google 之前破壞其原始 DKIM 簽名，然後查閱 o365/exchange 文件或向 Microsoft 詢問此欄位的用途以及在轉發之前更改它的原因簽名郵件。
