Empty all mailbox ?

[nameless']

Hello,

I'm looking for a way to empty all mailboxes (ie all folders, subfolders) of all acounts on my Zimbra server.

Any way to do that ?

I tried this in a script which use a userlist : zmmailbox -z -m xxxx@yyyy.com emptyFolder *

But it only accept a specific folder mail, and some users have special named folders :/

Thanks for the help
