电子邮件标头中显示的主机名

我使用 Postfix 作为 SMTP 服务器，并且我不希望我的服务器主机名出现在电子邮件标头中，我应该做哪些更改？

正如您在下面的代码中看到的，这是主机名：server1.example.com

以下是完整标题：

答案1

您可以更改 helo_name 设置，但正如 DandyPandy 所指出的，接收 SMTP 服务器仍会反向查找您的 MTA 的 IP 地址并记录下来。

答案2

您对此无能为力。您所能做的就是配置您的服务器以宣传另一个名称。有时，请使用白标域名，这些域名不会明确表明它们来自谁。但这是标准，并且标头的这一部分是由接收服务器 (gmail) 放置在那里的。
