District Spam Filter

Managing Your Quarantine Inbox

Barracuda Spam Filter quarantines messages that contain information the system sees as spam. It provides users the ability to check quarantined messages, classify messages as spam and not spam, and manage whitelisting and blocking email addresses. You can access your account from the following link using your network User ID and Password: https://cuda.gccisd.net


Quarantine Summary Report

The Barracuda Spam Filter sends you a Quarantine Summary Report daily if you have quarantined spam. This summary report enables you to view the quarantined messages. From the Quarantine Summary Report you can also add messages to your whitelist, delete messages, and have messages delivered to your inbox.


Note that the Quarantine Summary Report only goes out if new quarantined mail is saved in your account since the last notification cycle. Each day the quarantine notification service runs for all users. If there is no new quarantined mail for your account since the last notification cycle, or if you have logged into your account since then, no quarantine summary report will be generated and sent to you for that same 24 hour period. Note also that links in the quarantine digest for viewing, delivering, whitelisting or deleting a message from the quarantine inbox expire in 15 days from the date the digest is sent out.

Using the Quarantine Interface

At the end of every Quarantine Summary Report is a link to the quarantine interface where you can set additional preferences and classify messages as spam and not spam.


Logging into the Quarantine Interface

To log into your quarantine interface:

  • Click the "Manage your allowed/blocked list" link provided at the bottom of the Quarantine Summary Report (displayed above). The login page appears.
  • Enter your network username and password, and click Log In.

Using your Quarantine Inbox
After logging into the quarantine interface, you'll see the QUARANTINE INBOX listing your quarantined messages. When you first start using the quarantine interface, you should view this list on a daily basis and classify as many messages as you can. Clicking on an email displays the message.


The following table describes the actions you can perform from this page.

Adding Email Addresses and Domains to Your Whitelist and Blocklist

The PREFERENCES > Whitelist/Blocklist page lets you specify email addresses and domains from which you do or do not want to receive emails.


  • Whitelist - The list of email addresses or domains from which you always wish to receive messages. The only time the Barracuda Spam Filter blocks a message from someone on your whitelist is when the message contains a virus or a disallowed attachment file extension.
  • Blocklist - The list of senders from whom you never want to receive messages. The Barracuda Spam Filter 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. The only time a blocklisted email address is delivered is if the same email address also appears in your whitelist.



To whitelist senders or to add senders to your blocklist, follow these steps:


  1. Go to the PREFERENCES > Whitelist/Blocklist page.

  2. A list of your existing whitelisted and blocklisted addresses appears on this page.
  3. To delete a whitelist or a blocklist entry, click the trash can icon next to the address.
  4. To add an entry, type an email address into the appropriate field and click the Add button.


Tips on specifying addresses

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

  • If you enter a full email address, such as johndoe@yahoo.com, just that user is specified. If you enter just a domain, such as yahoo.com, all users in that domain are specified. If you enter a domain such as barracudanetworks.com, all subdomains are also included, such as support.barracudanetworks.com and test.barracudanetworks.com.
  • Mass mailings often come from domains that do not resemble the company's website name. For example, you may want to receive mailings from historybookclub.com, but you will find that this site sends out its mailing from the domain hbcfyi.com. Examine the From: address of an actual mailing that you are trying to whitelist or blocklist to determine what to enter.
