You are right.....I also did not get the automated reply when I submitted CSE to NDVO. FOr the same matter I also wrote to their e-mail address & they replied(automatic) as belownavigogana said:I had raised the CSE to NDVO, I thing that's why I didn't got any automated mail from NDVO.
"Your e-mail was received by the New Delhi visa office. We do not respond unless you have already submitted an application and we need additional information from you. If a response is justified, we will write within 30 days. We do not provide status updates on applications in process. We do not confirm receipt of documents or passports."
From above part of email, it seems NDVO does not generally replies to queries but only communicates if they have to ask for any documents/updates from applicant.
