To whom was the letter addressed?
Who was the letter addressed to?
A strict grammarian would prefer the first sentence, because it doesn't end in a preposition. Also, strict grammarians love the word whom.
I've got news for you. Nobody speaks or writes this way today--unless they intend to write with affected intelligence and annoy their readers. Now you can do both at the same time.
Hell, nobody even knows what the word whom even means.
We no longer live in the 19th Century. This writing style, as grammatically correct as it may be, sounds increasingly pretentious by the year. Loosen up people!
