Today, Zimbra offers by default a per-use Spam folder which gets to receive spam and from which users can recover false positives.

For various non-technicall (i.e. political) reasons, we would like to have a global quarantine folder for spam and not let spam goes to each user's Spam folder so a team of local admins can periodically check this global quarantine folder and release false positives.

Is there an oficially supported way to accompilsh that using Zimbra ? For this case, we are using Zimbra Network Edition version 7.1.1 under Red Hat Enterprise Linux 5.6.
