I've had users sending copyrighted files (songs, videos) to each other over email. I blocked the file extensions .mp3 etc. What some users have done is to rename files to .doc etc.

I cant block .doc etc filetypes because they are needed for day-to-day work.

I'm using MDaemon 12 mailserver, Does anyone know how to make it block these attachments? I've been working on some content scanning for filetype code, but was wondering if there is a already made solution?
