Wont that be called false charge of defamation?India,see details?

Suppose some man 'R' sends an insulting letter containing unfair comments ; to some coworker 'S' at his home.
S gets hurt after reading that %26 HIMSELF shows that letter to his whole family %26 a group of people.
Now can S prosecute R under provision of defamation in India??
Answer:
Definitely he can prosecute R for the offence of defamation under section 500 of the Indian Penal Code as here a letter was written containing unfair comments that amounts to defamation as provided under section 499 of IPC as Whoever by words either spoken or intended to
be read, or by signs or by visible representations, makes or publishes
any imputation concerning any person intending to harm, or knowing or
having reason to believe that such imputation will harm, the
reputation of such person, is said, except in the cases hereinafter
excepted, to defame that person.
Now in this case this letter was read by his whole family %26 a group of people before whom his reputation was harmed by such imputation, hence it amounts to defamation.
