Upgraded from ZCS 6.0.4 to 7.1.2 last night. Everything looks successful from an upgrade standpoint. Having some trouble now with workflow though..

We receive messages into submission mailboxes which are then immediately forwarded to a clearance dept mailbox. Emails are often sent to a few submission mailboxes at a time for business reasons. This method in Zimbra 6 forwarded each email to the clearance mailbox leaving 2 or 3 copies of the email (1 for each original division to be worked seperately of the other division). I guess Zimbra 7 is smarter now as it de-duplicates the emails being forwarded and only leaves us with 1 copy of the email in that clearance box. Is there a setting to change this back so that all emails that are forwarded are sent to the clearance box as it was handled prior? Or any other helpful ideas? Really don't want to roll back for this but it is the major flow of our business.

Thanks
