Add NGINX & Certbot installs for SSL solution?

[adamzea]

Would it make sense to add an NGINX web server install, server block config for mail.yourdomain.com, super basic index.html, certbot install, and config to the script to make it even easier to deploy on a fresh server? Or would that cause other problems?

(BTW, used your script yesterday to make a server intended for use with Delta Chat and it worked beautifully! Thanks!!)
