help for the rationale of using a punctuation mark in a letter?
In a business letter, it starts with Gentlemen:
Why is it that colon is used not comma?

Salutations in a formal or business letter end with a colon instead of the traditional comma... it's not required, but it's appropriate etiquette.
So, where one might write:
"Dear Tom and Linda," if they were being informal. They would write, "Dear Mr. and Mrs. Smith:" in a formal address. (They almost might leave out the "dear.")
