邮件传递失败

Question

我得到了这个反弹。它是什么意思，我该如何解决？感谢。

MailEnable: Message Delivery Failure.
Reason: ME-E0193: [B7C2FA717C634859B59BCACF7D8C38A8.MAI] Message Delivery Failure.

Your message addressed to the target domain could not be delivered because
the mail server responsible for this domain returned a permanent error.

The server returned: 554 5.7.1 Delivery not authorized

Answer 1

这可能意味着垃圾邮件过滤器阻止了邮件。

尝试从电子邮件网络服务发送相同的邮件，看看是否遇到同样的错误。
