Currently, AFAIK admins need to use the CLI to manage the email messages that have been quarantined by the antivirus. The messages can be seen by opening the antivirus-quarantine mailbox, but the messages cannot be released from the quarantine. In order to release them, the admin needs to use the CLI to inject the messages into the milter queue, avoiding Amavis.
IMHO there should be a way of:
- Releasing the messages to their original recipients
- Releasing the messages to alternative recipients, or
- Deleting the messages
