Quarantine

• CASG scans all messages received by your mail server to identify spam and malicious email.

• If enabled by your administrator or by yourself, you will receive notifications when a mail sent to you or your aliases is quarantined.

• The notification mail contains a link to view the message. The link will expire after 24 hours. See 'Manage Profile Settings' for more details about enabling/disabling quarantine mail alerts.
  

• The notification mail contains links to request the mail is released from quarantine, to whitelist/blacklist the sender or to delete the mail from quarantine.

• If you want to release the mail from quarantine or blacklist/whitelist the sender, you need to login to the CASG user interface and open the quarantine interface.

• The 'Quarantine' interface shows mails addressed to you but quarantined by CASG. You can view the mails and even download attachments from them if you are sure they are safe. You may also send requests to your administrator to release quarantined emails or add senders to the whitelist or blacklist.

Note: Please contact your administrator if you are not able to view your quarantined mails.

Tip: You can configure CASG to send you regular quarantine reports. The report lists all your quarantined messages. See CASG Reports for more details.
