So I recently upgraded to 7.1.1 on my Ubuntu server for my company's mail and two strange errors arose. First, messages were constantly deferred and I attributed it to the mail spam/virus filter. I disabled the filters and restarted and mail worked again but now I don't have the filters up. Second, daily mail reports are sent with nothing in them; all the values are zero. The zimbra.log under the /var/log directory is empty as well. I checked to make sure logger was running and it was. Any ideas were to start dissecting these problems?
