Thanks
Whoopsi, forgot to mention an important thing.
Our ZCS collects all the mails from an external provider with pop, and I would need it for that purpose. We started with every user turning that option off, so the mails were still stored on our providers servers in case our Zimbra server didn't work properly, but now with ZCS running fine and these boxes getting overfilled, I want to do this from one place to make sure it gets done instead of writing a mail to all affected users that they should do it themselves.
In short, ZCS works as the client in our case
