Postfix
使用 gmail 在我自己的域中驗證電子郵件地址
我需要能夠使用 gmail 的 Web 界面發送電子郵件，但要讓它們看起來來自我自己的域，而不是來自 gmail 地址。為此，gmail 會詢問我的 smtp 伺服器的資訊（url、帳戶等）並繼續驗證，確實，我被允許使用我自己的 smtp 伺服器（postfix，託管在我的利諾德）。
Gmail 的響應是“您的其他電子郵件提供商響應速度太慢。請稍後再試，或聯繫您其他域的管理員以獲取更多資訊。” - 無法從他們那裡得到更多的細節。
我根據Linode 的 Centos 7 教程為 Centos 7設置 Postfix、Dovecot、MariaDB並嘗試適應我的需要，在 Chuan Ji 題為“使用 postfix 和 gmail 的自定義域電子郵件”的教程中找到了一些說明（即我根據那裡的建議生成了一個 .pem 文件，包括我的 smtp 伺服器的名稱作為通用名稱 - 證書中的 mail.tcs-usa.com 以使 gmail 滿意）。
我可以使用後綴作為我的 smtp 伺服器使用 Thunderbird 發送電子郵件，並且我已將後綴配置為將發送到我域中任何地址的傳入電子郵件轉發到我的 gmail 帳戶。這工作得很好。我還使用 mxtoolbox.com 檢查了我的 smtp 伺服器，它還按順序找到了所有內容。
我在下麵包含了 postfix 日誌的摘錄。唯一讓我想到的是第 11 行的“match_list_match: mail-yk0-f169.google.com: no match”和第 12 行的另一個。
如果我包含太多資訊，請提前感謝您的所有幫助和道歉，但我已經在這兩天了，但沒有得到任何地方。

正如所承諾的，我現在發布了一個解決方案，因為我找到了它：而不是使用伺服器 smtp.mydomain.com 的名稱，只要我使用伺服器的 IP 地址，問題就消失了。Google 能夠驗證，現在我可以從我的 gmail 帳戶發送電子郵件，而不會在 from: 或 sender: 欄位中顯示 gmail 或 google。
很可能，這與我的 dns 記錄的設置方式有關，但我想我會推遲嘗試弄清楚它現在正在工作。
