esackbauer So, what to do now to publish records for info.viveksahu26.com.

What is now the correct hostname for your server? info.viveksahu26.com or mail.viveksahu26.com.
And what is your mail domain? viveksahu26.com or info.viveksahu26.com?
And why don’t you post the results of the test sites?
And what do the postfix log say when you try to send to gmail?

hostname od server: ip-172-31-3-89 (Do we need to set hostname of server too ?)
mail domain name: mail.viveksahu26.com
domain name of server: viveksahu26.com
email: info.viveksahu26.com

On sending mail from gmail to info.viveksahu26.com, I got this in reply to my gmail

Postfix logs are:
`

vivek There is so much wrong, that I don’t know where to start…
Are you sure you have a basic knowledge of SMTP? Email adresses are written with @, not with dot. And then you can’t even write your own email address in Gmail properly? You missed a “k”…
And then you mix up “mail domain name” and “domain name of server”.
You cleary lack understanding of the DNS system. And the difference between private and public IP addresses.

I would recommend you start all over by reading this page:
https://docs.mailcow.email/prerequisite/prerequisite-dns/
And please follow all links on that page which explain more.
