电子邮件传递速度慢，软 spf 通知

Question

我们有一个服务器，可以保存电子邮件并将其转发到我自己的 Google 邮箱（[电子邮件保护]）。

这些邮件被延迟了，当查看邮件源时，我注意到了这个 spf 软失败：

(google.com: 正在转换的域名 [e-mail] 未将 176.31.117.132 指定为允许的发件人

我应该在哪里以及做什么来解决这个问题？我的 nowhow.be Google spf 记录？

Answer 1

该邮件似乎是由 mandrillapp.com 发送的[电子邮件保护]。而且似乎 textthebutler.be 的邮件服务器将邮件转发到[电子邮件保护]无需改变信封发件人。

由于 textthebutler.be (tesla.mdware.org) 的邮件服务器未列在 mandrillapp.com 的 SPF 记录中，因此您会遇到软失败，因为 Google 收到了来自 tesla.mdware.org 的邮件，其信封发件人为 *@mandrillapp.com

所以我认为问题出在转发邮件服务器 (tesla.mdware.org) 上。此服务器需要实施某种重写方案 (例如 SRS)，以使邮件不会通过 SPF 检查。
