You are very close you want to make the projections in your map file like
the below:
Tanya
MAP
#--------------------------------------------------------------------------------
#---------------------------------MAPFILEHEADER----------------------------------
#--------------------------------------------------------------------------------
PROJECTION
'init=epsg:3857' #projection of the map
END
#--------------------------------------------------------------------------------
#-----------------------------------WEB-SECTION----------------------------------
#--------------------------------------------------------------------------------
WEB
WMS_SRS "EPSG:3857" #projection of the service
END
#--------------------------------------------------------------------------------
#-------------------------------------LAYER--------------------------------------
#--------------------------------------------------------------------------------
LAYER
...
PROJECTION
'init=epsg:4326' #projection of the layer
END
...
END
END #end map
