我有几台 RHEL 6 服务器，我已配置 yum-cron 在这些服务器上运行。我已将它们配置为将电子邮件输出发送到我的地址。问题是，除了一台服务器之外，其他所有服务器仍在向 root 发送邮件。我肯定我漏掉了一些简单的东西，但我还是想找出是什么。有什么建议吗？
在下面的配置和日志中，ServerOne 将消息传递到正确的地址，而 ServerTwo 则没有。
以下是来自 ServerOne 的邮件日志：

最后，来自 ServerOne 的 Postfix 规范文件：
[email protected] [email protected]

以及来自 ServerTwo 的 postfix/canonical：

@something.com [email protected]

答案1
找到问题了。从 yum-cron 文件中：
如果设置了 MAILTO并且邮件命令可用，mail 命令用于传递 yum 输出
在这种情况下，我必须安装 mailx yum 包。
