Except as otherwise provided by these rules or statutes, service of process and proof of service shall be made by the methods provided in Rule 4 of the Idaho Rules of Civil Procedure. Service of process shall be made by the sheriff of the county where the service is to be made, or by a deputy, or any other peace officer or other suitable person appointed by the court.
