服务器电子邮件仅被Gmail视为垃圾邮件

我正在开发一项服务,让用户通过电子邮件将我们的内容发送给他们的朋友。 问题是这些电子邮件通常以垃圾邮件结束。 所以我经历了所有的东西,使我的服务器发送正确的头(SPF,DKIM,rDNS等)的好电子邮件。

现在,电子邮件的标题已经很干净了,而且正在通过hotmail或yahoo收到,但在Gmail中仍然被标记为垃圾邮件! 我完全疯了,因为我无法弄清楚我做错了什么。 用户订阅时的欢迎消息具有几乎相同的模板,但不被视为垃圾邮件…

这是一个标题(我隐藏的IP和域)的示例:

Delivered-To: [email protected] Received: by 10.68.217.163 with SMTP id oz3csp61408pbc; Thu, 17 Jan 2013 05:07:39 -0800 (PST) X-Received: by 10.194.172.228 with SMTP id bf4mr8314430wjc.38.1358428059148; Thu, 17 Jan 2013 05:07:39 -0800 (PST) Return-Path: <[email protected]> Received: from mail.mydomain.com (mail.mydomain.com.

有任何想法吗 ? 提前感谢!

PS:

我在html中使用2个图像,2个指向mydomain.com的链接,2个社交链接和一些文本。 我使用了http://www.zurb.com/playground/responsive-email-templates上的模板
