Linux 现在正在向我发送垃圾邮件（anacron）

大约一年前以来，linux Debian 一直向我发送垃圾邮件，如下所示：

Subject: Anacron job 'cron.daily' on mymachine
Content-Type: text/plain; charset=UTF-8
Date: Mon,  3 Apr 2017 07:35:04 -0400 (EDT)

/etc/cron.daily/logrotate:
reading config file /etc/logrotate.conf
including /etc/logrotate.d
reading config file apt
reading config file aptitude
reading config file consolekit

(1) 有没有办法通过单一设置来阻止这种情况，或者我是否需要单独找到每种垃圾邮件类型的动机并单独解决？

（2）如果我需要解决这个问题，一次一封垃圾邮件，我该如何处理上面粘贴的anacron问题？

（3）为什么现在会出现这种情况？我的 Debian 机器已经使用了至少 6 年，大约一年左右我才开始收到垃圾邮件，现在我的邮箱中有 577 封此类邮件。

如果您以 root 身份登录并运行

/usr/sbin/logrotate -v /etc/logrotate.conf

您将在屏幕上看到该输出。问题是-v你必须删除它。你会-v在这里找到：

$ grep -r logrotate /etc/cron*

输出示例：

/etc/cron.daily/logrotate:test -x /usr/sbin/logrotate || exit 0
/etc/cron.daily/logrotate:/usr/sbin/logrotate -v /etc/logrotate.conf

当cron获得一些输出时，默认情况下它会被邮寄给 user root。
