We did that before, for sure.

But there are NO working solutions for that and the problem still exists
and ist a massive problem, because a simple version upgrade doesn't work
and leads to a DOS of the infected systems.

The repair script hasn't worked at all with our kind of Maildir-Filenames.

If others run into the same problem:

We used this simple piece of code (which is much easier to read and adapt):

for FILE in * ; do
        SIZE=`zcat $FILE | wc -c`
        NEWNAME=`echo $FILE | sed "s/\(.*\)S=.*:\(.*\)/\1S=$SIZE:\2/g"`

        if [ ! $OLDNAME = $NEWNAME ] ; then
                echo mv "$OLDNAME"    "$NEWNAME"
