As an administrator, you now have the option to enable read receipts for users who send encrypted messages using the Barracuda Email Encryption Service. This is disabled by default and must be enabled per domain. To enable, go to Domains and click ‘Edit’ for the domain you wish to enable read receipts for. Under Encryption, select ‘Yes’ for 'Enable Read Receipts’.
When read receipts are enabled, an email notification will be delivered to the sender when the recipient opens their email. Learn more
