The kanji 郵 is a phono-semantic compound (形声文字). The left side is 阝 (also written as 邑), which is a "building" radical and suggests a place, or location. The right side is 垂, which is a phonetic component, representing the sound "yuu" and originally meant "to hang down." Combined, the character originally might have represented a station where things were delivered. Over time, the meaning evolved to specifically relate to postal services and the transportation of items and correspondence.
