我正在开发一个Web应用程序。
所有外发电子邮件都被标记为垃圾邮件，或被接收者的电子邮件提供商完全拒绝
这可以防止我们向注册用户发送欢迎电子邮件，激活码或其他任何内容。
我用isnotspam.com测试了我的电子邮件发送，问题似乎是BAYES_99和BAYES_999指标。无论电子邮件内容如何都会发生这种情况。
有人能告诉我为什么会这样吗？ 有没有办法通过垃圾邮件过滤器将外发电子邮件标记为垃圾邮件？
这是isnotspam.com测试结果的结果（我为隐私修改了一些参数）。

我完全恐慌地发布了这个问题，我们公司在推出新产品时遇到了麻烦，客户不满意我们正在努力寻找问题所在。
最后，我们收到的电子邮件不是因为垃圾邮件检测，而是因为我们的服务器配置错误。有些条件导致电子邮件根本无法发送。
这个故事的主要内容是：如果您在发送电子邮件时遇到问题，请确认您是否发送了有效的HTML（例如通过validator.w3.org），并在考虑垃圾邮件之前检查您的服务器配置。
