我已经在我的服务器中配置了Postfix和Dovecot(在这个服务器中我是我的网站和我的邮件服务器),但如果我发送电子邮件,它会被标记为垃圾邮件!我也配置了DKIM !!

所以,这里有一些信息:

$ host MYDOMAIN.COM
MYDOMAIN.COM has address 178.62.48.51
MYDOMAIN.COM mail is handled by 50 mail.MYDOMAIN.COM.

我的posfix main.cf:

我无法解释为什么电子邮件会收到垃圾邮件,有什么建议吗?

我强调在代码中我使用了我的真实域名。我还强调在某些文件(如主机名)中我使用了域名,但是我不知道它是否正确(例如:我使用DOMAIN而不是DOMAIN.COM)。

1 个答案:

答案 0 :(得分:0)

您在评论中提供的IP地址,确实由DigitalOcean拥有,对我来说确实看起来很干净w.r.t. DNSBLsSpamHausSenderBase等IP信誉网站。也就是说,DigitalOcean在控制其客户时肯定有bad reputation。对于广泛的DigitalOcean IP范围,出站垃圾邮件和某些过滤器可能过于激进。

我注意到您的IP rDNS中的域恰好缺少MX记录。在这种情况下,许多反垃圾邮件系统会拒绝您的邮件,特别是如果这是您实际发送的域名。您似乎覆盖了FCrDNS的其余部分,我认为这也是您的HELO所反映的。

(如果您想从您的问题中撤回IP,我已经省略了对您的实际IP或域的引用。)
