What sorcery is this? Email notifications

[JLH1825]

So I received a couple of email notifications today about a SMART error and a backup completing. That's nice. But I don't remember EVER setting up email notifications (in fact, from what I've read, it seems beyond my experience as of yet). How could I be getting these emails?

Here's the message:

Subject: [EXT] SMART error (ErrorCount) detected on host: hitprox

This message was generated by the smartd daemon running on:

host name: hitprox

The following warning/error was logged by the smartd daemon:

Thanks!

You entered an e-mail address during installation of Proxmox? It can also be found in the Proxmox Datacetner Users administration. The installed smartmontools will e-mail root when it detects a problem. This is not uncommon on Linux systems. E-mails to root will be forwarded to the aforementioned e-mail address.
