Quick-n-dirty Postfix and Dovecot setup for an internal notification server

Two of my least-favorite open source products are Postfix and anything that interfaces with it. I use Postfix and Dovecot extensively and still find new annoyances with both of them. My major gripe is the lack of a simple package in Ubuntu that simply asks questions and then automatically does stuff based on the answers to set up a working mail server.

The objective of this post is to show a simple setup of Postfix and Dovecot for Ubuntu 14.04 LTS to enable command-line scripts on a box on a local network to send e-mail to itself and then retrieve those e-mails over POP3 using a normal e-mail client.

The code review is about ego boosting/ego crushing disguised as a quality assurance practice. Well, that's what happens in a lot of code reviews and, when it happens, it is a form of bullying.

Also, the code review involves not only judgment but the peers are the jury and executioner in some sort of twisted intervention:

Intervention: "an occasion on which a person with an addiction or other behavioral problem is confronted by…
