Since the number of (extensive) Ansible examples are still sparse, I decided to clean up the ones I have been writing and release them, for reuse and educational purposes. I know I would've benefited greatly from them when I started out, and hope they will help others now. I have a couple more of them, but they need some additional clean-up before I will add them to the repo.
Inspired by the "NSA-proof your e-mail in 2 hours" article, I created a similarly complete setup for a personal (mail/web/...)server on a VPS as al3x did a couple of weeks ago using the scripts I had, and wrote an idiot-proof tutorial on how to set it up (https://github.com/pjan/the-ansibles/blob/master/docs/cloudbox.md). Manual steps are minimal, and "It just works" - start to finish should take you less than an hour.
If you haven't tried Ansible before, there's no more excuse not to now.
Enjoy.
