Note

This walkthrough is part of the Cloning Gmail’s Architecture series. For better context, I suggest you to start from Part 1

In this tutorial, we will look how to configure a mail server (iRedMail) on the EC2, assign an Elastic IP (static public IP), enable port access for SMTP / IMAP communications and more, to replicate an actual email flow from server to server.

Pre-Requisites Link to heading

You have access to a linux environment where you want to configure iRedMail.
Network connection on that linux environment.
Privileges to run the commands as a super user.
A TLD domain to setup mail server’s hostname and configure settings.

Info

Make sure to replace example.com with the domain that you have registered with your DNS provider. Use of example.com is for merely demo purposes to showcase how DNS mapping is working.

So I was setting up this new VM and spent almost my whole day in copying my files from previous installation to this new one… Now, as for me… I am a little curious for trying up new things to see how they act out. Sometimes I don’t even see that I am using my actual machine to try those stuff out… And VMs end up crashing, as of me hindering with those config files at a regular intervals. So, I wanted there to be a system that whenever I install a new VM. I could easily just copy paste my previous machine state to my new state.
