Hi there. I tried setting up a Mail in a box SMTP server on my DIgital Ocean droplet: https://www.digitalocean.com/community/tutorials/how-to-run-your-own-mail-server-with-mail-in-a-box-on-ubuntu-14-04

Unfortunately though this tutorial is out of date now, and when I try to install Mail in a box, I get the following error:

“Mail-in-a-box only supports being installed on Ubuntu 14.04, sorry. You are running: Ubuntu 16.04.3 LTS

We can’t write scripts that run on every possible setup, sorry.”
