    ==============HELP HELP HELP==============
    I did everything as mentioned in this video
    But still unable to send email.
    Also not showing any kind of error message.

    I have a questions to ask
    1. I have created fresh ec2 instance and start using the steps as mentioned in this videos. Do I need to have anything else more to configure in this VM.

    2. I used sudo apt install postfix > it shows already install. But when running this command "postfix –version" it doesn't show anything | same with mailx command | ==============What's the issue do you think?
