User is not configured in the User List for List Management.
1. To ensure that the quarantine user has the ability to have their own approved/blocked senders list, check if the user is listed under List Management. This can be found under Dashboard > Services > Anti-Spam, select the Domain name, List Management
2. If the user is not found, depending on the configured settings, ensure that the user is listed as a group member. With the example below, the user has to be under the User Control for the approved/blocked sender option to appear in the Quarantine portal.
3. After the user is properly configured, save the settings by clicking Save and Exit.
