In order to prevent the impersonation of our trusted brand and avoid any confusion and risk for our customers, Barracuda Networks is taking steps to harden our email sending domains to enforce DMARC policy. This important measure will prevent the potential threat of an adversary looking to impersonate Barracuda Networks to cause any harm to our customers. 

As we implement this control, we advise all of our customers to change their notification email address(s) and the SMTP server setting on their Barracuda Networks appliance(s) to use their domain/email address instead of 'Barracuda'. Please do so to ensure your email provider accepts your notification emails from your Barracuda Networks appliance. 

To change the email addresses for System Alerts and System Message Emails:

1. Go to the BASIC > Administration page.

2. Scroll down to the Email Notifications section.

3. Enter a Domain Name – (Only with Firmware v9.2.2.002 and higher. Skip this step for earlier firmware.) A valid email domain to be used as the sender email address for system generated alerts and notifications. This will be used as the "From" address when generating system alerts and notifications. For example, if the domain entered is mydomain.com, the "From" address used for system generated alerts is alert@mydomain.com. 

4. Set the System Alerts Email Address to an address you want to receive alert emails. For example,  Myadminalerts@gmail.com.

5. Set the System Contact Email Address to an address you want to receive system message emails. For example,  Mynotifications@bcompany.com.

6. Click SAVE at the top right of the page.

To change the From address for Reports sent by the Email Security Gateway, the Reports From Address field on the normally hidden Expert Settings page will need to be updated using the following steps.

1. Go to any of the ADVANCED pages. (Example: ADVANCED > Email Protocol.)

2. The Expert Settings tab is not yet visible. Add &expert=1 to the end of URL in the browser's address bar.
   The end of the URL may look something like this: &primary_tab=ADVANCED&secondary_tab=email_protocol_checking&user=admin&expert=1

3. Click on the Expert Settings tab, which is now shown in red.
   
   

   Open

   

4. Change the Reports From Address from the default setting to reports@yourdomain.com or something else that uses your company domain name.

5. Click Save.
