Spammers like to use web-forwarding URLs to advertise. How do I block these URLs on my Barracuda Spam Firewall?

Solution #00001731

Scope:
All Barracuda Spam Firewalls, firmware versions 3.4 and above.

Answer:
It's not uncommon for spammers to use web-forwarding for their adverstising. Usually, spammers will place a URL into the body of a spam email, hoping for the recipient to click and visit their website. Web-forwarding occurs when one domain redirects traffic to another domain. For example, here's how traffic may redirect with web-forwarding:

domain1.com/products --> domain2.com/products

The Barracuda Spam Firewall can follow the links in emails to see whether they redirect to a known spamming domain using a feature called Multi-Level Intent Analysis. This can be enabled on the Basic > Bayesian/Intent page of the Barracuda's web interface.

Additional Notes:
For more information about Multi-Level Intent Analysis and other Intent domain blocking, see Solution #00001581.
