Hi Andrea, If jpeg output isn't working for your there is something wrong with your installation (maybe the jpeg library is not properly linked).
I think that JPEG output is useful for orthoimages. Most other maps where you have a lot of homogeneous areas with few colors are better handled by PNG 8bit. PNG is somewhere in between. As you said - only PNG can handle transparency, if you add TRANSPARENT=TRUE in your GetMap request. I don't think that you can filter the available output formats with QGIS server. I also think that it is not too useful to filter the formats. There may be WMS clients that can only handle JPEG and not PNG or vice/versa. You don't want to exclude these clients. You never know exactly who your clients are - so better offer a wider selection of formats.
