我已经花了 2 个小时试图解决这个问题，现在我打算放弃并去睡觉了。我一直遇到 Gmail 拒绝来自我的 VPS 服务器的电子邮件的问题，因为错误的垃圾邮件警报（可能是由于 lfd 发送了太多电子邮件造成的）。
因此，我更改了 Exim 配置，从不同的 IP 发送电子邮件（我的 VPS 附带 3 个 IP），这解决了该问题。我还在我的域上启用了 DKIM 和 SPF 以增加措施。但现在，我的所有电子邮件都显示为（“发件人：发件人姓名 via server.domain1.com”），其中 server.domain1.com 是我的 VPS 主机名。我以前在 Outlook 中遇到过同样的问题，关闭“设置 SMTP 发件人：标头”解决了该问题。但我相信添加 DKIM 和 SPF 现在会让 Gmail 将“via server.domain1.com”添加到我的邮件中。我该如何解决这个问题？
这是邮件的典型标题（如在 Gmail 中显示的一样）：

我在这里找到了答案： http://blog.tekipad.com/2009/11/exim-and-multiple-domains-php-mail-function-and-junk-mail-issue/
基本上，您需要在 PHP mail() 调用中添加第五个标头，内容如下：“-f[from_email_address]”
并且还向您的 exim 配置中添加一个新变量：trusted_users = [可以修改发送地址的用户 ID 列表（以冒号分隔）]
做到这两点就成功了。:)
