office 2007 files block as x-zip !

ENSAN_ironport — Thu, 12 Nov 2009 19:06:12 GMT

hi i got a problem with docx files
Ironport S160 (AsyncOs v6.3.0-604) recognizes it as application/x-zip. I know why!

Office 2007 files are XML contained within a zip file.

I would like the s160 recognizes docx files as application/x-docx and not as x-zip, because i block zip extentsion but not office2007 files.

It sounds like you should contact customer support, and if it becomes necessary, they can open a bug or a feature request with engineering to change this (depending on what they say the problem is/isn't).

Cheers,

They are actually zip files. You may even rename them to .zip and open
