The answer is in your first message, I should have read it better. You are using 3.9.4.1 which is almost a year old. Filetype detection was improved in 4.0. That file detects correctly using the latest version, 4.2.1.1.
Please note that using an old version means you do not have several security, performance, and functional enhancements.

We are on 4.2.1. I will post the next time I see a block regarding the issue I posted earlier.

I suspect I know the problem.

There are two levels of file type detection. One is a quick one that is done based on the first 4k of the file and can be performed before the file is fully downloaded, the second is a more accurate one that is performed by the virus scanner on the full file.

If you set a site to be "Trusted" then you are turning off the virus scanner for all downloads from that site. As a consequence you are also turning off the more accurate file type detection.

So if you have set groupspaces.com to be Trusted in your Local Site List, then any docx that you download will not be virus scanned and will not be correctly detected as a Word Document.

A simple workaround would be to not set to trusted. A more complicated one would be to leave it as trusted but also add a tag to the site. Then create an additional policy that applies to that tag and sets allow for zip files.

I suspect your are onto something, however sometimes we set sites as trusted so that they load faster when it is a frequently used site. Especially if  we have used for quite some time.
