Anti-virus Settings
Anti-virus protection is enabled for each server when the Zimbra software is installed. The global settings for the anti-virus protection is configured with these options enabled:
Block encrypted archives, such as password protected zipped files.
Send notification to recipient to alert that a mail message had a virus and was not delivered.
During ZCS installation, the administrator notification address for anti-virus alerts is configured. The default is to set up the admin account to receive the notification. When a virus has been found, a notification is automatically sent to that address.
By default, the Zimbra MTA checks every two hours for any new anti-virus updates from ClamAV. The frequency can be set between 1 and 24 hours.
