Qatar will want to see the email confirmation. If you are a making a direct connection at Doha it's likely your visa eligibility will most likely be checked at your originating airport, where the DOH MAA boarding pass can be issued.
That should hold even if the Chennai sector is on Indigo, but the Qatar-Indigo interface can be a bit clunky when it comes to the finer details such as seat allocation.
