As long as you have the correct information on the "File Command =" line
in your mailscanner configuration, it should be as simple as adding a
line like:

deny    MP3             No mp3s                 No MP3 files allowed

into your filetype.rules.conf file.  The file command is usually
"/usr/bin/file", but it might be different on your distribution.  Try
"which file" to find it on your system.
