Email Gateway Defense (EGD) UI outage incident report

As there was an extremely high number of affected customers and emails, Email Gateway Defense is unable to manually rescan and redeliver mail that was incorrectly blocked due to this incident. To help remediate the high number of emails, administrators can allow end users to redeliver their mail:

  1. The administrator signs into Email Gateway Defense. Under the Users tab, select Default Policy.

  2. For the Allow end users to view and deliver blocked messages, click Yes if the option was previously set to No.

  3. Click Save Changes.

Users will now be able to login and deliver their incorrectly blocked mail.

Note that administrators must advise users to proceed with caution as this will potentially allow users to send mail that should not be delivered. If administrators are concerned about future user behavior, they can reset this setting to No after mail has been delivered from this incident.

What's New as of April 25, 2023

Added a temporary passcode authentication method feature to allow users access to their shared mailbox and distribution list accounts. Enable the feature on the Users > Quarantine Notification > Allow users to sign in with temporary passcode page. 

For more information, see Quarantine Notifications and Temporary Passcode Authentication. See also

Note that the administrator feature under Users > Quarantine Notification >  Require login credentials to access quarantined messages has been removed.

What's New as of March 31, 2023

Auto-authentication has been disabled for end users from quarantine email digests. End users will now be required to authenticate before they can view their account and make updates to their quarantined emails.  

In addition, the administrator feature under Users > Quarantine Notification >  Require login credentials to access quarantined messages has been enabled to Yes for all users and greyed out to ensure that all end users must log in to view their accounts. 

For more information, see

What's New as of February 8, 2023


Barracuda Networks expands new end user interface to Email Gateway Defense. 


  • This platform launch is a 1-for-1 migration from the old framework, which means that there are no new features/capabilities at this time, just a new “skin” or “look and feel.” However, this migration will allow us to add new features or make changes to our products much more quickly in the future.

  • This launch is for the end user portion of the product only. We’ve begun work on the admin interface and will have a beta version available for users to try.

  • This new interface will be rolled out slowly to end users over the next 4-6 weeks (beginning February 8th, 2023). For the new user guide, see Email Gateway Defense New User Interface User Guide.

  • Only accounts with a “User” role will see the new UI. If you have set a user as a “domain admin” or “helpdesk” role within EGD, they will need to be set to “user” in order to see the new UI. This is NOT the same thing as setting up an administrator through Barracuda Cloud Control.

What's New in Version 2.8.9

Web Interface and Mail Processing
  • Anti-Phishing Protection

    • Link Protect – When enabled, automatically rewrites any URL in an email message to a safe Barracuda URL, and then delivers the message. If the user then clicks on that URL, the service evaluates it for validity and reputation. If the domain is determined to be valid, the user is then directed to that website. This feature protects users who click URLs in email messages from being directed to a spoofed website or otherwise revealing private information such as logins, passwords or other sensitive data. Note: Link Protect does not properly protect URLs in plain text messages which lack a character set identifier. See also Anti-Fraud and Anti-Phishing Protection.

    • Typosquatting Protection – Automatically corrects spelling of domain names that hackers miss-spell by one letter to fool the user into thinking they are visiting a valid site by clicking the URL in an email. In reality, the domain name, misspelled, would direct the user to a phishing site. For example, would be re-spelled correctly by the service as before the email is delivered to the user to protect them from being directed to a suspicious site.

  • Anti-Fraud Intelligence and Intent Domain Policies settings have been moved to the INBOUND SETTINGS > Anti-Phishing page.

  • Miscellaneous improvements and bug fixes.

In the Received headers, the Barracuda Email Security Service will continue looking beyond a Trusted Forwarder IP address until it encounters the first non-trusted IP address. At this point, Rate Control, SPF checks and IP Reputation checks will be applied. Configure  on the INBOUND SETTINGS > IP Address Policies page.

    • BLOCK FAIL - The SPF FAIL (also referred to as Hard Fail) response indicates that the IP address of the message sender does not match the IP address or range of IP addresses specified in the sending domain name's SPF record, and that the real owner of the domain has specifically indicated that such messages should be rejected (blocked) as spoofed.

    • BLOCK FAIL, SOFTFAIL - The SPF SOFTFAIL response indicates that the message sender's IP address does not match the IP address or range of IP addresses specified in the sending domain name's SPF record.
