Polygon outline width

Here is my mapfile. The complete Mapfile has 8 other layers but I
removed them in order to make it easy to read, anyway all layers have
the same properties (only the color change).
I also tried to set the OUTLINECOLOR property at the CLASS level and to
use the value -1 0 0 but the outline is still not transparent.
