ITRV receiving confirmation

I have recently sent the ITRV to Bengaluru....but in ITRV Status in income tax efiling website shows that ITRV is not received.... although according to speed post India website it shows that it has delivered the ITRV on the evening of 12 sept to IT department.
In how many days after delivering by speed post...ITRV Status shows received by Department? and when one will get the SMS and email by Department regarding ITRV receiving confirmation?
