But I would be careful with rm while developing the script, perhaps do a
echo $d
first, to see what would be removed.

I also think this does not work with a nested hierarchy. Try this
for a simple nested hierarchy:
mailhier="~/temp/mails"
for md in `find $mailhier -type d \( -name cur -o -name new -o -name tmp
-execdir pwd \; \) -prune`; do
if [ `find "$md" -type f | wc -l` -eq 0 ]; then
echo "$md"
# rm -r "$md"
fi
done
