I'm pretty sure it's installed as default on some debian machines, all depending on your selections during installation. And if it's a VPS they prob. use a standard mirror with sendmail as a standard package.
That most certainly seems to have been the case here.
Thank you! I seem to be turning blind. I missed that line in grep!
Removed sendmail, updated i-mscp, and now smtp service is running. So we're back to the initial issue. Mail sent from the server goes through fine. But the server cant receive mail.
Code
- Delivery to the following recipient failed permanently: [email protected] details of permanent failure:Google tried to deliver your message, but it was rejected by the server for the recipient domain joel.co.in by r2d2.joel.co.in. [50.7.228.37].The error that the other server returned was:550 5.1.1 <[email protected]>: Recipient address rejected: User unknown in local recipient table
Dig of my MX record yields this:
The FQDN of my server as set on the VPD panel is r2d2.droidzone.in. Is this what is supposed to be set up?
Other records are as follows:

Is there a mistake somewhere?
Latest mail logs are again uploaded. I've got to solve this somehow. 
Are PTR records essential? I've submitted a request to my VPS host to turn on rDNS for me, but apparently the request needs to be sent through their main data centre to get activated.
My postfix config:
