Set up msmtp to send emails emails from Ubuntu/Debian Servers

Setting up email with SMTP on Ubuntu/Debian Servers

I used to sift trough my shell history and bookmarks every time I set up a new testing server in order to be able to send mails. So this should help...

Be aware don't use ssmtp anymore. It's unmaintained and has been removed from Debian and Ubuntu will most definitely follow suit.

Shadow DOM

Heads Up! It's all about the V1 Spec.

In a nutshell, Shadow DOM enables local scoping for HTML & CSS.
