问题描述
这个问题与编程没有直接关系，但我需要我的服务器通过垃圾邮件过滤器才能让我的应用程序正常工作.我和我的 ISP 讨论了 rDNS，技术支持人员告诉我，如果我写一封电子邮件，说明他们应该添加到我的 DNS 记录中的内容，他们会这样做.我的问题:
This question is not directly programming related but I need my Server to pass Spam filters for my app to work properly. I talked to my ISP about rDNS and the guy from tech-support told me if I write an email with what they should add to my DNS record they would do that. My question:
如果我的主机名是http://niklasfi.de"，我应该告诉他添加什么?78.31.67.216?
What should I tell him to add if my hostname is "http://niklasfi.de" and my is 78.31.67.216?
感谢您的回答.我尝试在网络上搜索，但我只搜索了有关单个 ISP 的非常具体的答案.
Thanks für the answers. I tried searching on the Web but i only very specific anwers concerning a single ISP.
推荐答案
反向 DNS 只是一个记录，其中查找是从您的 IP 地址中找到您的主机名.所以你应该让他用你的主机名为 78.31.67.216 添加一个反向 IN-ADDR 条目.
reverse DNS is simply a record where the lookup is to find your host name from your IP address. So you should ask him to add a reverse IN-ADDR entry for 78.31.67.216 with your hostname.
这将是:216.67.31.78.in-addr.arpa niklasfi.de
this would be: 216.67.31.78.in-addr.arpa niklasfi.de
这些也称为 PTR 记录.
These are also known as PTR records.
