Good question ! -> is there a answer?

It is a very serious security issue.
Any user can upload a file from home and introduce it in the office (and viceversa) via the briefcase!
It is a main problem!
The admin shoud be able to block it within Zimbra!
What about creating this option in the users administration?

Try in Admin Console, Global Settings/Attachments. I think you can set to block file types (extensions) there.
