电子邮件发送失败

我已经知道我的问题的答案，但我需要指出一个可靠的来源来支持我的说法，所以我请你用简单的术语描述你对这种情况的看法。

我具体的问题不是为什么交付失败，而是两者之间的关系[电子邮件保护]和[电子邮件保护]

情况是这样的：

发送电子邮件至[电子邮件保护]几天后，您会收到一封电子邮件，内容如下：

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

<[email protected]> (expanded from <[email protected]>): host
    mailstore1.europe.secureserver.net[68.178.213.243] refused to talk to me:
    421 p3plibsmtp02-12.prod.phx3.secureserver.net CMGW Temporarily rejected.
    Reverse DNS for ZZZ.ZZZ.ZZZ.ZZ failed. IB108  <http://x.co/srbounce>

答案1

您用于发送电子邮件的电子邮件服务器缺少正确的反向 DNS 记录（IP 地址到域名映射）。

您需要联系电子邮件服务器的托管服务提供商，并添加与正向 DNS 条目（域名到 IP 地址映射）匹配的适当的反向 DNS 条目。
