Cannot find quarantined virus files
I'm currently running 8.0.4 but yesterday I was running 8.0.0 for several months. I've had previous versions but can't recall how far I go back. In all the versions I've never had to retrieve a quarantined e-mail until the other day. From my search on how to do this, it appears I first need to find the file. I looked in/opt/zimbra/data/amavisd/quarantine, but I only see files that start with badh- and spam-. I don't see any files starting with virus-. I upgraded to 8.0.4 today hoping this would fix my issue, but a test with eicar shows that I get the alerted e-mail, "The message has been quarantined", but I still cannot find the file in that directory. During the upgrade process I saw it state that the virus account exists. Either I'm looking in the wrong location or my virus quarantine is not working. How can I fix this?
Thank you for your help,
