Question

使用电子邮件工具向测试用户发送电子邮件，即isemailu5@slc00bly.us.oracle.com，电子邮件服务器为slc00bly.us.oracle.com。并得到以下问题，我认为这应该是一些postfix配置问题，我应该如何解决它？：

ERROR:

Answer 1

此问题可能是由您的DNS服务器引起的;

编辑“/etc/resolv.conf”并尝试：

nameserver 8.8.8.8
nameserver 4.2.2.4
nameserver 192.168.1.1
nameserver 127.0.0.1

或您的其他DNS服务器。

Answer 2

在/etc/resolv.conf更改后，这件事发生在我身上一次，后缀卡住了。一个简单的后缀重新加载解决了该问题。

注意：但是在重新加载之前，请确保/etc/resolv.conf中的名称服务器正确。

Answer 3

重新启动NetworkManager后，我的案件status=deferred (delivery temporarily suspended: Host or domain name not found. Name service error for name=email-smtp.eu-west-1.amazonaws.com type=A: Host not found, try again)错误已解决

sudo systemctl restart NetworkManager

暂停交付：找不到主机或域名。 name = localdomain type = A：找不到主机的名称服务错误
