I am in the process of implementing Zimbra within my organization. We have a Barracuda anti-spam filter that tags spam with [IS_SPAM] in our subject lines and I would like to create a rule for all users that puts this in a folder named Spam. Is this possible to do in Zimbra? Ideally, I would like to do this without turning on the AS/AV filters in Zimbra. Thanks.
