I believe that it is simply taht. One mail icon shows as a sent and another shows as a recieved. There will be a difference in the mail picture like a green arrow pointing in and a red arrow pointing out. That is how it is with my message log. Another phone I have just has a sent folder and a inbox folder.

Do you mean to refer to the Order of the Arrow?
The green arrow is what is often known as a "filter." This means vehicles are permitted to proceed with caution in the direction indicated by the arrow.
A green arrow showing same time as a red light proceed carefully in the direction of the arrow after yielding the right-of-way to other vehicles and perdestrians
the blue arrow means its a boy and the red arrow means its a girl.
This means you cannot turn. If you are in a turning lane and you see a red arrow you must wait till it is green before advancing.
It means stop first then can proceed if clear
In the U.S., a Red light always means stop. If the red arrow is to the right, you may turn after stopping if it is clear. In many states you may turn left on a red arrow after stopping if turning onto a one way street.Check your local jurisdiction for traffic rules on red arrows.The new national standard prohibits turning on red at a red right arrow.The red arrow is like the circular red, except that it applies to only the traffic making that turn.
You can turn right on a red light and a left red arrow. If there is a sign that says "no right turn on red" or it's a right red arrow, you can't turn right.
