cPanel 服务器电子邮件到 Gmail 标记为垃圾邮件、SPF、DKIM 和 rDNS 通过

在托管多个域的 cPanel 服务器 11.34.1 上出现此问题。来自 sendingdomain.com 地址上的此邮箱的电子邮件被 Gmail 标记为垃圾邮件。我已经实施了 SPF 和 DKIM,它们都传递到下面的电子邮件标头中。发送 IP 未打开,黑名单和 rDNS 已设置并正确解析。我不知道还能尝试什么来解决这个问题。

答案1

Google(或任何其他 ISP)的垃圾邮件检测系统很大一部分基于您服务器的 IP 信誉。如果您的 IP 信誉较低,那么无论 DKIM/SPF 是否通过,它都会被标记为垃圾邮件。

您需要检查您的声誉http://www.senderscore.org/

对于 WHM,您可能希望根据站点的 IP 路由电子邮件。如果您有多个 IP,这可以减少跨站点影响,或者允许您绕过继承的不良 IP。

答案2

按照此处的 Google 批量发送指南操作,如果你已经收到邮件,但仍被标记为垃圾邮件,可以快速“进一步故障排除”页面,最终批量电子邮件支持团队的联系链接

他们应该能够提供比这里任何人都更好的帮助。

答案3

根据我的经验,gmail 会将所有通过 PHP mail() 函数发送的电子邮件发送到垃圾邮件。roundcube 等 CPanel 网络邮件解决方案使用它。

我发现避免被发送到垃圾邮件的最好方法是从 SMTP 服务器发送电子邮件。它可以是自己的服务器的邮件服务器。重要的是发件人经过身份验证。

我希望 roundcube 开发人员能尽快找到使用 SMTP 的方法。

Wordpress 也使用相同的 PHP mail() 函数,有一些插件可以让你使用 SMTP 并使你的电子邮件正确传递,例如WP 邮件 SMTP
