GMail 将邮件检测为垃圾邮件

我一直在努力让公司的邮件服务器发送能够被 GMail 垃圾邮件过滤器接受的邮件。我已成功让它适用于 Yahoo Mail 和 Hotmail，但遗憾的是 GMail 仍将我们的邮件标记为垃圾邮件。

我已经配置了 DKIM、SPF、DMARC，并根据黑名单验证了我们的邮件服务器 IP 地址。我还在此处粘贴了我们发送邮件时 GMail 收到的标头。

多谢！

答案1

我在其他场合也看到过这种情况，当收到的消息被报告为本地主机时，IP 地址为 127.0.0.1。

事实上，这与您的 DNS 记录不匹配，肯定会将您的电子邮件标记为垃圾邮件。

您应该检查 DNS 记录（A 和 MX）以及您在 SMTP 服务器中发送的标头。您的服务器正在发送它认为是其 IP 地址的内容，因此您需要配置 /etc/hosts 以让您的服务器知道您的服务器的外部 IP 地址是什么。

答案2

如果您要向多个收件人发送几乎相同的邮件，那么处理 GMail 时最重要的两个标头是：

Precedence: bulk

和

List-Unsubscribe: http://your-site.com/[email protected]

当然，指向一个真实且有效的取消订阅页面，谷歌的取消订阅机器人可以轻松点击取消订阅，而不会受到奇怪的 javascript 或验证码或类似内容的困扰。
