Service of notice expanded to include electronic mail, fax, courier and newspaper publication where affixation is impracticable. Amendment expands service of notice to include fax, electronic mail, courier and speed post with acknowledgement; fax must note transmission and page count for annexures; electronic mail must be digitally signed and bouncing will not amount to valid service. If notice cannot be affixed on the outer door, service may be effected by publishing the notice in at least two newspapers: an English national daily and a widely circulated regional language newspaper where the person was last known to reside, carry on business or personally work for gain.
