I'm trying to setup two CentOS7 systems with automatic security updates to run as my kubernetes nodes. I've also centralized all my outgoing mail through my mailgun service, so I've been using the cli tool "mailx", which I have configured with my credentials. Coming from Fedora32 and CentOS7, dnf-automatic had a helpful emission target that was "email_command". By default it sent notifications using this command. With yum-cron, all I see is "email", which doesn't appear to use the "mail" command. I would like to set up something myself to send the daily yum activity, but it's not clear at all where I should expect the yum-cron "stdio" output to end up at. I "started" the service, which is really just creates sentincal file to allow the yum.daily cron entry to run. However, when I look at /var/log/yum, there's nothing there of interest. I can see that it claims to have run, but I have no idea what it did. Is there another place I should be looking for what this actually did? Separately, I'm looking for a way to confirm its behavior. I was able to do this on my dnf systems by downgrading a package, but if I use `yum downgrade X` on this CentOS7 system...it just reports success and does nothing. Any ideas about that one? -GN

I've written a little blog article on how to configure everything: https://blog.microlinux.fr/yum-cron-centos-7/ Cheers, Niki -- Microlinux - Solutions informatiques durables 7, place de l'?glise - 30730 Montpezat Site : https://www.microlinux.fr Blog : https://blog.microlinux.fr Mail : info at microlinux.fr T?l. : 04 66 63 10 32 Mob. : 06 51 80 12 12

I'm asking where the results of the yum-cron job are actually written to so I can see what it did. I want this because I want the `email_command` type functionality that's found in dnf-automatic with future OS versions, but is not present in yum-cron. -GN

Here's the content of an email sent by Yum-Cron.
