Quarantine Notifications

  • Last updated on

If you make setting changes, allow a few minutes for the changes to take effect.

The Barracuda Email Security Service can send notifications (quarantine digest) at predefined intervals to users as well as reports summarizing outbound quarantine information to the administrator. The administrator can view all quarantined outbound messages from senders within the organization and select to delete, reject, deliver, or export those messages from the Overview > Outbound Quarantine page.

You must generate a user list before enabling quarantine. For details on setting up users in the Barracuda Email Security Service, see the following articles:

User Quarantine Notification

Set the notification interval for all users, or select to allow users to set their own notification interval. You can also select to never send quarantine notifications. When set to Yes, messages that would be blocked by intent are instead quarantined.

Set Default Interval for All Users

  1. Log into the Barracuda Email Security Service as the administrator, and go to the Users > Quarantine Notification page.
  2. For the Notification Interval, click Scheduled.
  3. Click and drag in the Schedule notification intervals section to select the day and time.
  4. Set Allow users to specify interval to No.
  5. Click Save Changes.

Allow Users to Set Interval

  1. Log into the Barracuda Email Security Service as the administrator, and go to the Users > Quarantine Notification page.
  2. For the Notification Interval, click Scheduled.
  3. Click and drag in the Schedule notification intervals section to select the day and time.
  4. Set Allow users to specify interval to Yes.
  5. Click Save Changes.
  6. When users log into their account, they can set their notification interval on the Settings > Quarantine Notification page.

Never Send Notifications

  2. For the Notification Interval, click Never.
  3. Click Save Changes.

You can require users to enter their login credentials before they can access quarantined messages. By default, this is set to No. Note that this option is available to account admins only and does not display when logged in as a domain admin.

Require Users to Login to See Quarantined Messages

  1. Log into the Barracuda Email Security Service as the administrator, and go to the Users > Quarantine Notification page.
  2. For the Require login credentials to access quarantined messages, click Yes or No.
  3. Click Save Changes.

Quarantine Digest

The quarantine digest (summary) is sent when new quarantined mail is saved in the user's account (inbox) since the last notification cycle. Each day the quarantine notification service runs for all users. If there is no new quarantined mail for a user since the last notification interval, no quarantine digest is generated or sent to that user for that same 24 hour period.

The links in the quarantine notification email allow the user to access their Barracuda Email Security Service user account without entering their username and password. The link is valid for seven days. After that, the user must manually log into https://ess.barracudanetworks.com.

The links in the Action column allow the user to:

  • Deliver – Click to deliver the message to regular inbox.
  • Allow List – Click to allow the sender. All future messages from the sender are allowed and go directly to the user's regular inbox.
  • Block List – Click to have the sender added to the block list.
