Zimbra MTA > Anti-Virus Protection

Anti-Virus Protection
Clam AntiVirus software is bundled with ZCS as the virus protection engine. The anti-virus protection is enabled for each server and a global virus quarantine mailbox is created during installation.
The Clam anti-virus software is configured to quarantine 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 message lifetime for this mailbox is 30 days.
By default, the Zimbra MTA checks every two hours for any new anti-virus updates from ClamAV.
