您的 Outlook 郵件客戶端，如圖所示：
未設置為使用SASL 身份驗證。Outlook 的“發件伺服器”對話框可能不是一目了然：“在發送郵件之前登錄到收件伺服器”表示不進行SASL 身份驗證，而是先進行 POP 驗證。但是，您的 Postfix 設置需要 SASL：
smtpd_client_restrictions = permit_sasl_authenticated從你的問題中不清楚你想做什麼。如果您真的想要 POP-before-SMTP，則需要執行諸如 pop-before-smtp 之類的守護程序來讀取您的郵件日誌並將 IP 地址添加到 postfix/smtpd 讀取的 db 文件中，如下所示：
smtpd_client_restrictions = permit_sasl_authenticated, check_client_access hash:/var/lib/pop-before-smtp/pop.db否則，只需在郵件客戶端中選擇“使用相同的設置…”作為身份驗證方法並使用 SASL。
