ZCS Administrator Guide 8.0

Open Source Edition

Anti-virus Settings

Anti-virus protection is enabled for each server when the Zimbra software is installed. The anti-virus software is configured to send messages that have been identified as having a virus to the virus quarantine mailbox.

An email notification is sent to recipients letting them know that a message has been quarantined. The quarantine mailbox message lifetime is 30 days.

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.

You can change the anti-spam settings from the administration console Global Settings>AS/AV page.

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. You can change this from the Global Settings>AS/AV page.

Note:

Updates are obtained via HTTP from the ClamAV website.
