Barracuda Spam Firewall

Barracuda Networks

Hood's IT department has implemented a Barracuda Networks Spam Firewall to control the massive amounts of spam targeting Hood College. The Barracuda Spam Firewall is an integrated hardware and software solution that is used to protect Hood email, both Faculty/Staff and Students/Alums, from spam, viruses, spoofing, phishing, spyware attachments, and denial of service attacks.  All email, before it is sent to a users inbox, is sent through the Barracuda Spam Firewall to be processed. Addresses that appear on your Whitelist are automatically sent to your inbox while addresses on your Blacklist are deleted immediately. The remaining email is scored (evaluated as to the likelihood that it is spam), and handled according to your configuration settings.   It should be noted that all outbound messages leaving Hood's network are also scanned.

The access and management of your spam firewall mailbox is conveniently handled via a web interface and your Internet browser. This allows you to manage your email filtering regardless of what client operating system, computer platform or email software you use. You can access the interface via the URL on or off campus.

What is whitelisting and blacklisting and how does it work?

Whitelists are lists of email addresses you always want to receive email from. Email that you "whitelist" does not get tested for spam although it will be scanned for viruses. You might, for example, whitelist a company you conduct business with if you want to receive their regular advertisements and not worry about the Barracuda quarantining messages from them. Tip: It isn't recommended to whitelist While the Barracuda firewall will give special consideration to email from Hood, spammers often use fake email addresses hoping to bypass spam filters. They won't bypass our filters by faking their address, but they will bypass yours if you whitelist

Conversely, blacklists are lists of email addresses you never want to receive email from. Email that you "blacklist" is automatically blocked whether or not it is spam. On rare occasion, the firewall might not catch spam messages from a particular sender. In this case you could blacklist the email sender. Blacklisting is not always effective because not only do many spam senders fake their email address, they will often change their email address after they spam a bunch of people.

To add/delete email addresses from your personal whitelists and/or blacklists, visit the quarantine and click the Preferences Tab. Then click on the Whitelist/Blacklist sub-tab.

Tips on specifying addresses

When adding addresses to your whitelist and blacklist, note the following tips:

  • If you enter a full email address, such as, just that user is specified. If you enter just a domain, such as, all users in that domain are specified.
  • If you enter a domain such as, all subdomains are also included, such as and
  • Mass mailings often come from domains that do not resemble the company‚Äôs Web site name. For example, you may want to receive mailings from, but you will find that this site sends out its mailing from the domain Examine the From: address of an actual mailing that you are trying to whitelist or blacklist to determine what to enter.
