Provided that if the authority issuing the notice is satisfied that an attempt has been made for service of notice by anyone of the abovementioned methods and the addressee is avoiding service or that for any other reason the notice cannot be served by any of the abovementioned methods, the said authority may, after recording his reason for so doing, cause such notice to be served by affixing a copy thereof in some conspicuous place in his office and of the last notified place of work and a notice so served shall be deemed to have been duly served:

Provided further that where the notice is served in accordance with the method stated in clause (iia), the provision of the first proviso shall not be applicable. 

(2)When a notice is sent by registered post, by speed post, it shall be deemed to have been received by the addressee on the expiry of the period normally taken by a registered letter in transit unless the contrary is proved.

(3) Where a notice is required to be issued by any authority electronically under any of the provisions of the Act or the rules made thereunder, such notice shall be issued under the digital signature within the meaning of Information Technology Act, 2000 (21 of 2000), of such authority, as may be authorized by the Commissioner for the purpose.
