Gmail SPF失败,基于客户端IP
Gmail无法通过基于客户端IP的SPF检查。这些是相关的标头: Received-SPF: fail (google.com: domain of johndoe@example.com does not designate 164.77.240.58 as permitted sender) client-ip=164.77.240.58; Received: from johndoe (unknown [164.77.240.58]) by mail.example.com (Postfix) with ESMTP id 993643FE2D 客户端IP(164.77.240.58)是johndoe计算机的IP。SPF记录中包含发件人IP(mail.example.com的IP)。 为什么Gmail失败基于客户端IP而不是发件人IP?SPF应该是这样工作的吗?
