Messiah simply means anointed one. being a messiah doesn't necessarily equate to being the son of God. I'm not sure how a messiah is different from a prophet. Perhaps a messiah is a savior who opens a dispensation of the Gospel. In that respect Joseph Smith would qualify as the Messiah Ben Joseph. The mission of the Messiah Ben Joseph was to restore the truth to the Earth in the latter days. According to prophecy his father would also be named Joseph. Also according to prophecy he would die at the hands of evil men before the age of 40. It isn't a perfect fit to Joseph Smith but it is a very good fit.
