Question

我遇到了在我们的网络服务器上发送邮件的问题。一些邮件发送和发送没有任何问题（例如Gmail），而其他邮件推迟“发件人地址被拒绝：未找到域名”

据我所知，这是一种垃圾邮件保护措施，可以在发送域上进行查询，但我们的域名包含MX记录：

Server:     8.8.8.8
Address:    8.8.8.8#53

Non-authoritative answer:
premiumconnect.co.za    mail exchanger = 10 za-smtp-2.mimecast.co.za.
premiumconnect.co.za    mail exchanger = 10 za-smtp-1.mimecast.co.za.

Authoritative answers can be found from:

（顺便说一句，为什么我们没有权威的答案？这可能是问题吗？）

以及A记录：

Server:     8.8.8.8
Address:    8.8.8.8#53

Non-authoritative answer:
Name:   premiumconnect.co.za
Address: 196.28.97.202

以下是尝试发送的特定邮件的日志：

我对Sendmail（或一般的MTA）没什么经验，不确定其他哪些信息可能有用。

编辑：我意识到这可能更适合SeverFault，会在那里重新创建。

此错误不是由您引起的问题，而是与电子邮件地址相关的问题您正试图发送：bookings@debian70.vm

如果你使用'whois'或其他dns查询工具查找debian70.vm，你会发现域名“debian70.vm”不存在。

有时您只会获得smtp错误代码，而不是单个单词，我会使用本指南查看它：http://www.greenend.org.uk/rjk/tech/smtpreplies.html

Sendmail：发件人地址被拒绝（未找到域名）
