These instructions will allow root to send email from the
system through a dedicated gmail account, as for example for
smartd monitoring.

Props to https://tecadmin.net/send-email-smtp-server-linux-command-line-ssmtp/
for the starting point for this information.

Sign up for a dedicated gmail account.

Turn on "allow less secure apps".

In /etc/smartd.conf, add a line like this before the line with DEVICESCAN in it:

/dev/sda -m your_email@domain.com -M test

The "-M test" says to send an email when smartd starts (in order to test the
email channel).

After reading a lot of pages about Promises, this page finally started making sense for me. It's a looong read and quite advanced but there are some good nuggets that help clarify things:

        https://pouchdb.com/2015/05/18/we-have-a-problem-with-promises.html

#. Always end a promise compose chain with

        catch(console.log.bind(console))

#. Inside a .then() ALWAYS RETURN OR THROW never let it be 'undefined'
