Archiving & Discovery server local mail

[atlee]

I'm using amanda to back up my Zimbra Archiving & Discovery server. Amanda runs locally on the server, which has a tape drive attached. I'd like local user amandabackup to send dump reports to the backup team. Since a Zimbra archive server does not have an MTA installed, the backup report messages bounce on the local machine. What do I need to do get these emailed reports on their way to Zimbra admin users' accounts on our ZCS server?
