See transparency & offsite options for the layer definition: http://mapserver.gis.umn.edu/docs/reference/mapfile/layer TRANSPARENCY 0 OFFSITE 255 255 255 I've only used it in my WMS server to provide layers with the white background removed. I'm assuming it will work in a client as well. Also ensure you are not using JPG images (I see you are using PNG24, but it is worth mentioning anyway :-), as they don't support transparency & can finish up with off-white pixels for white in the lossy compression.
