Sauron's original name was Mairon.
If you're referring to the guard who went out to meet them before the battle at the Black Gate, then that is the Mouth of Sauron, a Black Numenorean who is loyal to Sauron and is approximately 3,200 years old. He serves as the messenger of Sauron and is also considered the Lieutenant of the army of Mordor.
The Mouth of Sauron, in both the movie and the book The Return of the King, is a lieutenant of Sauron that knows Sauron's mind, so Sauron speaks through him. He is still a Numorean man, however, and hopes to gain much from Sauron's conquest of Middle-Earth.
Mouth of Sauron was created in 1955.
