Welcome to the forum, jainaa. Please follow the standard practice of beginning sentences and writing the first person pronoun 'I' with a capital letter and ending sentences with a single full stop (period) or question mark.

Dear Sir, It would be better to address him by name.
this abc, secretary of the organization. i got your reference from my senior xyz.....
Your name has been given to me by Peter Postule, with whom you worked five years ago.
He wants to know how you know him more than who you are. He can find that out by looking at the information below your signature:

Peter Postule
Company Secretary

I am a little puzzled about why you should ask for advice, and then ignore every word of it. Still, it's your letter; do exactly what you want.

I am sorry for repeating the mistake. I wasnt following the standard rules for the whole post.

Dear Rtn.Anirudh,

It gives me pleasure to get a the chance to get in touch with you. This isI am writing/emailing in relation to the management-based event that we are going to conduct this year at Rotaract Club.

I hope it is fine in the context I told you before.

See above.

Please remember to capitalise the word "I".
One full stop is sufficient at the end of a sentence.
There was no need for a capital letter at the beginning of the word "help".
