Verify Correct Address is Added to Barracuda's Blocklist

Barracuda's Blocklist is designed to be a list of senders from whom you never want to receive messages. The Barracuda Spam Firewall immediately discards messages from senders on your Blocklist. These messages are not tagged or quarantined and cannot be recovered. The sender does not receive a notice that the message was deleted, and neither do you.

Spammers will "spoof" or fake the address that appears in the From box. They do this to prevent future Spam emails from being blocked by anti-spam technologies like Barracuda. To successfully add the 'correct' address to Barracuda's Blocklist, you need to add the "X-Barracuda-Envelope-From" address.

Note: Based on time needed to do these steps AND the fact that the spammers typically never re-use the same spoofed addresses, your time would be better spent by just deleting the message from Barracuda's Quarantine or your Inbox.

However, if you consistently receive unwanted email from a specific address, you can follow these steps to add the correct address to the Barracuda Blocklist.

Determine "X-Barracuda-Envelope-From" Address from Quarantine

If a message you wish to add to the Blocklist is already in Barracuda's Quarantine, you can follow these steps:

    Note: A separate window (or a new Tab) with the email will open. At the top will be the From: and Subject: lines. The "From:" is what you would see here is the normal view of Outlook

  3. Click the View Source button.
  4. Highlight the email address next to X-Barracuda-Envelope-From:.
