Barracuda Sentinel - Allow Senders

Using Barracuda Sentinel’s Allow Senders list ensures MetaCompliance emails bypass your organisation’s current allowlisting rules. See Barracuda’s How to Allow Senders article for more information.

To add specific senders:

  1. Log in to your Barracuda admin console.
  2. Click Dashboard in your console menu.
  3. Select the 'Settings/cogwheel' icon.
  4. Click Allowed Senders.
  5. Enter one email address or domain name into the Sender Email or Domain field.
  6. (Optional) Add a comment to your email address or domain name.
  7. Click Save.

⚠️ Note: The hostname and sender domain will match the sender email address selected during phish creation (e.g. internalmail.info).
