Thanks, it works!

The recipe is:

* Declare the **target SRS** in MAP.PROJECTION and 
  MAP.METADATA.wms_srs

* Declare **only the source SRS** in MAP.LAYER.PROJECTION and 
  MAP.LAYER.PROJECTION.METADATA.wms_srs

* Declare the MAP.EXTENT, MAP.LAYER.EXTENT and 
  MAP.LAYER.METADATA.wms_extent using the correct SRS. This is 
  required to generate a GetCapabilities without warnings, 
  compatible with QGIS 1.5.0 too.

Here it is the actual mapfile (notes are in Italian only, sorry):
