Whoa, someone is talking about my code and I'm not even paying attention....

I have that code in prod and it works fine, but you must compile and
install the ytnef binary.

If you look at the code:

@new_files = `/usr/local/bin/ytnef -f Work $path`;

foreach my $file ( @new_files ){
  chomp( $file );
  push( @tnef_files, $file );
  md_syslog( 'info', "Found file $file in winmail.dat attachment" );
}

It uses ytnef to extract the files, if there are files extracted they
are later attached, if not, the winmail.dat file is deleted and nothing
is attached.

Hope that helps,
