This is a very odd problem as I've never experienced it myself, neither did I change the default setup to fix it.
I would say that the mailscanner filetype or filename rule files are bad and thus causing mailscanner to act that way, but could be wrong.
Replace the your files with the attached files, making sure to make a backup copy first.
So you would just have to drop them into the /opt/Mailscanner-version/etc folder. Make sure to unzip them first.
