Need step by step instructions for a linux mail server

I am looking for someone to put together a document that explains in step by step detail how to set up a mail server on an Ubuntu linux machine (using the latest Ubuntu).

The document must have every step including: installing the necessary packages, installing a certificate, setting up the mail domain, setting up an smtp server and pop3 server.

The setup must also include configuring the mail server’s domain through cloudflare.

The final document must be a Microsoft Word document with steps and screen shots when necessary.

Once I receive the finished document, I will use a virtual server to setup the mail server with the instructions provided. I will test the mail server with various Windows mail software to send and receive mail.
