Quarantine Notifications
If you make setting changes, allow a few minutes for the changes to take effect.
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.
You must generate a user list before enabling quarantine. For details on setting up users in Email Gateway Defense, see the following articles:

Quarantine Digest
Quarantine notification emails are sent based on the schedule you set for your users (for example, hourly or weekly). The service checks users in hourly cycles and, around each user’s scheduled time, looks for new quarantined messages since their last scheduled digest and sends a summary email if new messages are found, up to a limit of 250.
Clicking the links in the quarantine notification email lets the user deliver the message, allow the sender, or block the sender. These secure links use a two step confirmation: after clicking Deliver, Allow sender, or Block sender in the digest, the user is taken to a secure Email Gateway Defense page and must confirm the action before it is applied. Each link only performs the chosen action, and users must still log in to Email Gateway Defense to view the full message log and manage other messages.
The user can also manually log into Email Gateway Defense corresponding to their region:
Australia (AU) – https://au.ess.barracudanetworks.com
Canada (CA) – https://ca.ess.barracudanetworks.com
Germany (DE) – https://de.ess.barracudanetworks.com
India (IN) – https://in.ess.barracudanetworks.com
United Kingdom (UK) – https://uk.ess.barracudanetworks.com
United States (US) – https://us.ess.barracudanetworks.com
The links under each email allow the user to:
Deliver – Click to deliver the message to your regular inbox.
Allow sender – Click to allow the sender. The sender is added to your allow list. All future messages from the sender will go directly to your regular inbox.
Block sender – Click to block the sender. This sender is added to your block list.
