Is tds return compulsory for no tds deduction in quarter?

I have received following e-mail from CPC (TDS)

Dear Deductor,

As per the records of the Centralized Processing Cell (TDS), TDS Statements have been filed for Q2, FY 2013-14, however, no TDS Statements have been filed for Q3, FY 2013-14 as yet. In this regard, your urgent attention is invited to relevant CBDT Circulars and provisions of the Income Tax Act, mandating filing of TDS Statements and Issuance of TDS Certificates downloaded from TRACES.

You are advised to refer to Section 200(3) of the Act, read with Rule 31A, which reads as follows:

===============================

Now there was no TDS deduction by us in last quarter. AFAIK, if there is no  deduction, then there is no need to file return.

So above email has confused me. Is there any rule change? Is it ok if I dont file a TDS return for the quarter?

Do I need to reply to above e-mail or I can simply ignore it?

Thanks in advance.
