To Whom It May Concern:
Dear Mr. President is a salutation of a business letter. The salutation goes at the beginning, thus that's how you got Dear.
That part of the letter is called the salutation or greeting.
The reference line on a business letter is placed one space below the inside address and one space above the salutation; at the left margin on a block style or modified block style format, and center tab on a standard indented letter.
Using junior or senior in a salutation letter should only be done if these two words are a part of your name and you use it daily. The same rule goes for who the letter is for.
Business documents should be grammatically correct, and use proper spelling and punctuation. A business letter should also be clear and to the point.
After the salutation of a business letter, the correct punctuation to use is a colon.

Re:
In a business letter =P
A salutation is an addressing to the person that the letter is addressed to and in a business letter you should always start with "Dear" and then add something like "Sir" or "Madam" immediately after it.
