[exim] File extension filter not work

Hi!
Just wonder why these ACL does not reject some file extension???
When I was using old demime, all was working perfectly, since I have to
change to new ACL statement, I can still send exe,com,bat....
Any idea?
I use Exim 4.62 with content scan activated in compilation

    {${lc:$mime_filename}} \
    {\N(\.exe|\.scr|\.vbs|\.pif|\.bat|\.scr|\.lnk|\.com)$\N} \

   deny message = Found MIME error ($demime_reason).
