Sauron is a spirit, you could possibly call him an angel. He belongs to a race of beings called the Maiar, to whom the Wizards and the Balrogs are also a part. Maiar are lesser spirits that serve the greater Valar, themselves created by the creator himself, Eru Iluvatar to aid him in the world's creation.
Though a lesser angel, Sauron (then known as Mairon) was an unusually gifted one. He served under the smith Vala, Aule, which is the source of his magic ring-making skill. One of the Valar, Melkor (later known as Morgoth) rebelled against the creator and drew some of the Maiar to his cause, Mairon included, becoming his lieutenant. When Morgoth was defeated, Mairon took up his mantle as the new Dark Lord.
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.

The answer is no. Subpoenas are served to a person or entity, and only to that person or entity or an authorized person. For a subpoena to a person it has to be served only to that person or to someone living with that person at the residence. In the case of an entity it has to be served to someone who is authorized to accept a subpoena on behalf of the entity.
Sauron was played by Sala Baker.
