Your script does this:

        if [ number of regular files in $mailhier is not zero ] then
           for all folders in $mailhier/ do
               if [ number of regular files in $mailhier/folder is zero ]
                  then delete folder
               fi
           done
        fi

The thinking behind this for mbox format is different because you do
not have so many files...

A simply line will do:

   find $mailhier -empty -exec \rm -f {} \; 

or, if in a script, protect the sensitive characters (\, {, }, etc.):

   find $mailhier -empty -exec \\\rm -f \{\} \\\;
