我想确认邮件失败通知的含义。这是消息
Hi. This is the qmail-send program at mydomain.com
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
<[email protected]>:
1.2.3.4 does not like recipient.
Remote host said: 554 <[email protected]>: Relay access denied
Giving up on 1.2.3.4
我的理解是，没有设置 1.2.3.4 来接收该域的邮件。
挖掘 domain.com MX 节目
;; ANSWER SECTION:
domain.com. 6245 IN MX 10 mail.domain.com.
domain.com. 6245 IN MX 20 mx.anotherdomain.com.
（1.2.3.4 是 mx.anotherdomain.com。）。
令人费解的部分是我报告说从 gmail 发送的邮件会发送到此地址。
PS这是serverfault的正确问题吗？
这意味着传递邮件 1.2.3.4 必须将其传递到另一个邮件服务器（因为 1.2.3.4 不是最终目的地）并且它不想这样做。
