OT, but...

docx files are zip archives containing a number of xml files, so
Barracuda is recognizing the file by its content rather than by

Perhaps Barracuda would be willing/able to make their appliance perform
a more in depth content analysis to determine if this zip file appears
to be a docx or open document or Google Earth .kmz or other known file
type which is in fact a zip archive of other files, but apparently
they do not currently do this.
