A mailbox combines a box body and a support molded in one piece together with working hardware, such as a handle, a door or a hinge structure for closing and opening the door of the box. The support provides multiple mounting options through a leg with an elongated segment including an expanded foot, that can be embedded in a ground surface. Alternatively, the elongated segment is truncated to expose an open end of a hollow leg. The present invention also provides a process for molding a mailbox box portion and a post portion in one piece, with the box portion including a door, a box body, and a transition sleeve connecting the door to the box body. The sleeve is truncated from the door and the box body to form an open end on the box body, and the door is pivotally mounted at the open end of said box portion. A method for rotationally molding a one-piece product with two segregated exterior color portions includes separating first and second mold chambers in a mold part by a partition wall including an access opening filled with a barrier plastic. Separated color molding material is rotationally molded in each chamber until the barrier melts during the rotational molding process.
