[Mimedefang] File Magic

[Jared Armstrong]

Hello

Any concerns with using the File::Type module in filter() or 
filter_multipart()?

I am thinking of running something like: 

checktype_filename($entity->bodyhandle->path)

and then doing an action_drop_with_warning the offending part based on the 
returned file magic (especially executables).

I am already discarding filenames based on extension, but some of my users 
are learning to change extensions to get past the re_match check.

Good idea?  Bad idea?  Should I just shut up and try it?
