Got it guys , see Companies (Registration Offices and Fees) Rules, 2014, section 7 5th proviso. it mentions as below ;
"Provided also that any correspondences (physically or electronically) and documents to be filed by any person shall contain name, designation, address, membership number or Director Identification Number, as the case may be, of the person signing such document and make sure correctness thereof and in no case, correspondence, merely with signature and writing authorised signatory shall be acceptable"
