Zimbra Email - Copy all server emails

I am just wondering. Is it possible to copy all emails from any user in Zimbra, sent and received, to a master mailbox automatically? Retaining the sent from, sent to etc

The reason for this is my CRM software has a mail scanner and I do not wish to do it for every new user, instead i just want it to scan a 'master' mailbox.

Hope this makes sense.
