Enabling quarantine or blocking for a hosted mailbox
Answer ID 2366   |   Last Review Date 12/18/2018

How do I enable emails to be quarantined or blocked for our hosted mailbox?

Environment:

Incoming Email, Barracuda

Resolution:

With the Barracuda spam filtering that is available for each hosted mailbox, by default, the quarantine feature is disabled and blocking is set to 9. As a result, emails having a block score of 9 and higher will be removed.

Note: Depending on how your mailbox is configured within your Oracle B2C Service application, emails may be blocked based on the Discard Addresses and other Discard fields.

Exercise caution when enabling adjusting the Block score. Once an email is blocked, it is permanently removed and is not delivered and is not accessible. If there is any concern with permanently blocking emails, you can disabled this feature and use the quarantine feature so that those emails are sent to the Quarantine Inbox where they can be reviewed and evaluated.

Enabling the Quarantine Feature

Step 1: Enable Spam Filtering: By default, the Enable Spam Filtering option on the PREFERENCES: Spam Settings page should be enabled. Access the Spam Management Portal to confirm. If this option has been disabled for some reason, you must re-enable it in order for emails to be either quarantined or blocked. Click Yes and then click Save Changes in the heading line.

Step 2: Quarantine Score: To enable the quarantine feature, you must first specify a Quarantine score. This score defines the threshold above which email is quarantined. That is, if the Spam Score calculated for the email is greater than the Quarantine Score, the email will be quarantined. When the email is quarantined, it can be reviewed from the Quarantine Inbox tab. By default, the Quarantine Score has been set to 10, disabled. Setting this to anything lower than 10 enables this feature.

To modify the Quarantine Score, click the Preferences tab > Spam Settings. Then, edit the value for Quarantine Score and click the Save Changes button in the Spam Scoring header.

Step 3: Enable Quarantine: Next, enable the Quarantine feature. Click the Preferences tab followed by the Quarantine Settings option. In the top section, next to Enable Quarantine, click Yes and then click Save Changes in the Quarantine Enable/Disable heading.

If you wish, you can specify who should be notified of email that is in the Quarantine Inbox and also how often the notifications should be sent. Select the appropriate notification interval and also specify the notification address and then click Save Changes in the Quarantine Notification heading.


Enabling the Blocking Feature

Step 1: Enable Spam Filtering: By default, the Enable Spam Filtering option on the PREFERENCES: Spam Settings page should be enabled. Verify that this feature is set to Yes. If this option has been disabled for some reason, you must re-enable it in order for emails to be either quarantined or blocked. Click Yes and then click Save Changes in the heading line.

Step 2: Block Score: By default, the Block Score is set to 9. The Block Score defines the threshold above which the email is blocked. If the Spam Score calculated for the email is greater than the Block Score, the email is blocked and is not delivered.

To modify the Block Score, click the Preferences tab > Spam Settings. Then, edit the value for Block Score and click the Save Changes button in the Spam Scoring header.
