我正在尝试使用 postfix 和 opendkim 设置自己的 smtp 服务器。我已经发布了 spf/dmarc/dkim 记录，设置了 ptr。但目前，我所有带有文本的邮件都会进入 gmail 垃圾邮件文件夹。我查找了电子邮件来源，发现了这样的日志（我从[电子邮件保护]在我的账户上[电子邮件保护])：

正如您所看到的，我遇到了这个错误：
(google.com: domain of transitioning [email protected] does not designate 2a07:5741:0:eb4::1 as permitted sender) [email protected];
但是我的 spf 记录中有这个 ipv6，它看起来像这样：
"v=spf1 include:_spf.google.com ip4:94.156.35.221 ip6:2a07:5741:0:eb4:0:0:0:1 ip6:2a07:5741:0:eb4::1 ~all"
由于某种原因仍然软失败，我认为这是邮件最终成为垃圾邮件的主要原因。
