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.

Install msmtp

Delonghi Dedica 680 Rancilio Silvia wand modification (originally created by Chris Faulds)

This very detailed guide was originally written by Chris Faulds and used to be available at cfdesign.work/derancilio. Unfortunately, his website is no longer online. Thanks to the Wayback Machine the article is still readable. But since the presentation is a bit wonky, I decided to mirror his awesome tutorial is this gist.

Chris has spent a huge amount of time writing an in-depth instruction on how to take the machine apart, which may also come in handy for other repairs for the Dedica 680/685. Again all credits go to him. Thanks a lot for the great work!
