Your data is not in projection epsg:4326 as indicated by
<gml:boundedBy><gml:Box
srsName="EPSG:4326"><gml:coordinates>3449790.000000,5891640.000000

3463543.000000,5900876.00000
You need to find out what projection your data is in and then set that
projection in the mapfile layer
LAYER
PROJECTION
'init=epsg:4326' <------- change this value to the epsg code
of your data
END
SYMBOLSCALE 50000
NAME 'Testdatenlayer'
MapServer will then be able to reproject your data on the fly to
epsg:4326, which is the output projection of your mapfile.
