我现在正在做一个项目，发送电子邮件作为购买确认。有些电子邮件仍然被当作垃圾邮件接收。我已经注册了 google apps for business 的域名，并使用 PHPMailer 代码库（用于 sugarCRM、drupal 等）通过 google 服务器使用 smtps 发送电子邮件。我意识到邮件本身的正文内容可能是罪魁祸首。
然而，我很难理解的是标头。域名 ourgreatmovie.com 出现在标头的许多部分。这原本是我们使用的域名，直到我们更改为turnofthiscentury.com。我认为这可能是由于我为旧域名设置的反向 DNS 指针 - 但是我已让我的托管服务提供商将其更改为新域名并已验证了更改。
此外，我已经检查过/etc/hosts file；那里什么也没有 - 对于/etc/sysconfig/network（CentOS 6）也是一样；不再确定这个域名来自哪里；目的地收到的标头示例副本如下：提前致谢！

看起来它是邮件服务器程序正在发送的，因为它是 HELO/EHLO。
检查您的邮件系统中的此设置：[email protected]以及服务器在 SMTP 设置/通信期间如何识别自身的任何设置。
