我的smtp服务器成功发送电子邮件,但它们始终标记为垃圾邮件... 我不知道该怎么做,因为我几乎尝试了所有我知道的事情!

以下是测试邮件的示例,该邮件被Gmail标记为垃圾邮件:

有什么我错过的吗?

谢谢。

答案 0 :(得分:2)

简而言之:

您需要在DNS上为您的域添加正确的SPF记录,我还建议您为发送电子邮件的ip添加反向DNS查找。

长: 1.确保您的mailsender具有您在示例中发送电子邮件的实际域名:mail.mydomain.com应指向服务器的externa ip-address。此外,ip-address应解析为mail.mydomain.com

2.在您的DNS中添加SPF记录 这是一个例子: mail.mydomain.com。 IN TXT“v = spf1 mx a ip4:1.2.3.4/24~all”

  1. 还要确保您的邮件服务器配置正确。在exim4中,如果你将它用作smarthosts,则重写sendaddress。
  2. 祝你好运
