[Exim] bug or feature? maildirquota scans symlinks to other …

hello stuff,

i dont knwo if this is ok or if this behaviour is wanted, but as exim
creates the maildirsizefile, it also scans the files in symlinks.
i know thats not usual, but i use sometimes symlinks for easy creation
of shared-folders-like-folders ;-)

is this ok that exim scans symlinked-directories?

thanks in advance
