I just received a virus email, and it was mailed to the virus-quarantine account, but I cannot find the file in /opt/zimbra/data/amavisd/quarantine/.
Is this normal behavior? I find other files, but not this one.

And while for others notifications I get the file reference, for this one I got:

Content type: Virus
Internal reference code for the message is 30244-05/VZZZvl224pFB

The message has been quarantined as: virus-quarantine._upkctjcqj@DOMAIN.it
