【问题描述】：
最近决定放弃谷歌邮件服务并建立私人邮件服务器。我想到的是从me@example.com 发送到inbox@gmail.com 和spam@gmail.com 的电子邮件相应地放在Inbox 和Spam 文件夹中。
问题
为什么邮件会分到不同的文件夹？邮件目标文件夹（*@gmail.com）是否依赖于
- 帐户设置 - 当我的
gmail帐户中标记为非垃圾邮件时，我能够从me@example.com接收到Inbox的邮件？ - 服务设置 -
gmail的一些特定要求，例如，Received-SPF、DKIM-Signature等标头？ - 全局设置 - 超类、其他服务（yahoo、hotmail、outlook）、更多/更少标题？
留言
检查了某些标题字段中的pass'es。恕我直言，这似乎也很好。相应的 IP 是隐藏的。
