我正在尝试从包中激活通知电子邮件unattended-upgrade。我将邮件地址放入配置中，mailx在 中安装并创建了 mailx 的配置/root/.mailrc。我已mailx使用成功测试.mailrc。
信息：无人值守升级配置中的邮件与里面的邮件不同.mailrc。
我运行了unattended-upgrade -v -d --dry-run，但没有收到邮件。也没有关于发送邮件的调试信息。
那么我做错了什么？我找不到有关此类设置的任何信息或工作配置。
任何帮助都将不胜感激！
更新：补丁（安全）已正确安装。因此，该工具正在运行。我刚刚检查了服务器上的日志文件。但我仍然没有收到系统发送的邮件。是的：下面的邮件地址不是我的真实邮件地址。
