Email Gateway Defense 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.

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.

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.

Allow Users to Sign In with a Temporary Passcode

You can allow users to sign in with a temporary passcode. This is useful for users signing into a shared mailbox or distribution list, if users forgot their password, or if SSO is unavailable.

When the temporary passcode feature is set to Yes, users can request a temporary passcode when they click on a link in the quarantine notification email or when logging into Email Gateway Defense. A passcode is then sent to the user's email address that they can use to log in. If the user is using a shared mailbox or part of a distribution list, the passcode will be sent to the Shared Mailbox email address.

The passcodes are valid for 15 minutes. User sessions expire after 24 hours. By default, this is set to No. Only 5 passcodes are active on each account during any given 15-minute time window.

Note that this option is available to account admins only. To enable the feature for a specific domain, sign in as a domain administrator.

1. Log into Email Gateway Defense as the administrator, and go to the Users > Quarantine Notification page.
2. For the Allow users to sign in with temporary passcode, click Yes.
3. Click Save Changes.

For more information on this feature and how users can log into Email Gateway Defense using temporary passcodes, see Temporary Passcode Authentication.

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.

Clicking on the links in the quarantine notification email will redirect the user to log into their Email Gateway Defense user account using their username and password. The user can also manually log in using 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.

Note that quarantined messages are deleted after 30 days.

The quarantine notification also includes a link to take users directly to the blocked message filter in the Message Log. Click the link to view blocked messages.
