When I was young and installed my first Linux, I actually searched around as root if this was stored anywhere. But I never found it.

TL;DR: it's supposed to send email to an administrator, but by default on some distros (including Ubuntu), it isn't actually sent anywhere.
omg I totally accidentally enabled this
I'd bother removing it but it's kinda funny to get an email reprimanding me when I ctrl+c out of a sudo command I mistyped, and maybe it will serve as a warning if it gets compromised :p
I thought it's just a joke because I only had it on local PCs. Imagine my reaction when I actually got an email by an admin when using sudo on a network...
Distro-agnostic: /var/spool/mail or /var/mail; but both directories are empty on my system, and untouched since installation.
I'm sure one could make the incident report go there by installing one or two softwares. Would actually be interesting to see what it reads, since this message has caused many Linux newbs anguish.
$ sudo touch /root/beer# deluser SigHunter sudoNo touching!
