Miss. Code § 13-3-161
All sales by any sheriff by virtue of an execution or other process, when not issued by a justice court, shall be made at the courthouse of the county. The sheriff shall effectuate any execution on a judgment. However, personal property too cumbersome to be removed, may be sold at the place where the same may be, or at any convenient place. Cattle, sheep, or stock, other than horses and mules, may be sold at any public place in the neighborhood of the defendant's residence.
Sales of personal property under execution or other process from a justice court may be made at any convenient point in the county where it is found, or at the courthouse of the county. The sheriff shall effectuate any execution on a judgment. The sale of lands under executions or other process from such courts shall be made as under execution from the circuit courts.
