电子邮件故障传递

Question

我已经知道了我的问题的答案，但我需要指出一个有信誉的来源来支持我的说法，所以我想请你简单地描述一下你对情况的看法。

我的具体问题不是交付失败的原因，而是info@xxxx.xx和association@yyyyyyy.yy之间的关系。

情况就是这样：

几天后向info@xxxx.xx发送电子邮件时，您将收到一封内容如下的电子邮件：

This is the mail system at host mail.xxxx.xx.

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

                   The mail system

<association@yyyyyyy.yy> (expanded from <info@xxxx.xx>): host
    mailstore1.europe.secureserver.net[68.178.213.243] refused to talk to me:

Answer 1

用于发送电子邮件的电子邮件服务器丢失了正确的反向DNS记录(IP地址到域名映射)。

您需要与电子邮件服务器的托管提供商联系，并添加一个与前向DNS条目(域名到IP地址映射)匹配的适当反向DNS条目。
