A dual access mailbox 2 has front and rear closures 20 and 22 which actuate a signal member 28 from a non-signalling position to a signalling position and from a signalling position to a non-signalling position. A first arm 52 is pivotally mounted to the front closure and a second arm 54 is pivotally mounted to the second closure. Both arms are pivotally and slidably mounted to the signal member. As the front closure is moved to the open position, the first arm engages the signal member and pivots the signal member to the signalling position, and as the second closure is moved to the open position, the second arm engages the signal member and pivots the signal member to the non-signalling position.
