Sendmail無法發送到Gmail帳戶

Question

我正在vps上運行小型IRCd。 沒有防火牆。 當用戶注冊昵稱時， Sendmail會向他們發送一個確認電子郵件，發送到他們在注冊過程中輸入的電子郵件地址。 除Gmail用戶外，所有用戶均會收到電子郵件。 我發現了這一點，並使用我的IP地址創建了一個spf記錄，並將其放置在MX記錄中：

"v=spf1 ip4:168.235.75.84 include:_spf.google.com ~all"

但是仍然沒有收到Gmail電子郵件。 這是/var/mail/root的一些文本

對於它的價值，我為我的域設置了一個IPv6地址。

我在這方面不在聯盟之列，不知道我在做什么錯嗎？ 如果我需要發布更多信息，請提出建議。 謝謝。

Answer 1

您的SPF記錄應包括您的IPv6地址。

"v=spf1 ip4:168.235.75.84 ip6:2604:180:3:284::8c64 include:_spf.google.com ~all"
