I set up a beacon that tracks disk usage on all the Ubuntu Server 16.04 minions on Ubuntu Server 16.04. We wanted a reactor that emails us when disk space reaches a certain point. This question focuses on the master's ability to send an email. When I run the following command on the salt-master:
sudo salt-call smtp.send_msg '[email protected]' 'Test message 3' subject='Test subject 3' profile='smtp-default'
I get the following result:
[ERROR ] An un-handled exception was caught by salt's global exception handler:

I have uninstalled and reinstalled the salt-master and salt-minion and I have updated Python and the salt-master. I also created another salt-master and it ran into the same problem. What is the fix or solution to this?
I have discovered that the error has nothing to do with the installed Python libraries or if my system is updated or not. I found that I did not have an SMTP server set up and that I need to create an SMTP mail server or have an accessible SMTP mail server in order to send emails as notifications of the reactor system. I discovered that the solution was to set up an SMTP mail server and then create a .conf file in the /etc/salt/minion.d directory that referenced an SMTP mail server like so:
smtp-default:
smtp.sender: [email protected]
smtp.server: 0.0.0.0
smtp.tls: false
After creating a .conf file similar to the one above and the profile of the salt-call command referring to the function declaration of the state file, I was able to send emails to the desired address.
