Create linux install script for a fully working Web- and Mailserver (Ubuntu 16.04)

I want an [login to view URL] script for Ubuntu 16.04 It should install and configure some Application to run a fully functional Web- and Mailserver with following Applications. Webserver ----------------- Apache2 with ready configured virtual hosts for two sub-domains MySQL php 5.6 phpmyadmin certbot for SSL support (letsencrypt ) Mailserver ----------------- Postfix - SPF, DKIM and DMARC (I'll set the records on my own) opendkim Dovecot for IMAP and POP3 support Webmail client like roundcube smtp server should work with authentication and must support TLS/SSL Other Applications ----------------- vsftp and an extra user ready configured to access web root folder vnc4server on port :1 Thats pretty much It. All configuration should make by yourself I'll not specify examples. For testing purposes I can provide a fresh installed Linux Ubuntu 16.04 server.
