国外邮局大面积退信……

上星期起，发到国外的邮箱大面积的退信，而且很多之前都是能发送成功的。退信的内容大致上就分3种：

1.
I'm afraid I wasn't able to deliver your message to the following address.
This is a permanent error; I've given up. I am sorry for this inconvenience.
无法将您的邮件投递至以下指定地址:
[email=*****@vpc.co.uk]*****@vpc.co.uk[/email] : DNS lookup failed.

2.
I'm afraid I wasn't able to deliver your message to the following address.

无法将您的邮件投递至以下指定地址:
[email=******@kmg.com]******@kmg.com[/email] : Service unavailable.

3.

我测试过其中的大部分域名，都是可以解析到的。
请问各位是什么问题阿。
