The DCANet Email Firewall inspects each inbound message and places it into one of three categories: valid messages, unsolicited commercial email (spam), and messages that are suspect. Valid messages are quickly delivered to the user’s inbox. Clearly identifiable ‘spam’ messages are automatically rejected. Suspect email messages are held in a personal, web-enabled quarantine for later review, freeing the user from the distractions caused by unsolicited commercial messages.

After you sign up for a DCANet email account you will receive an email message with instructions explaining how to view and manage your quarantine. By visiting your quarantine, you will have the ability to review messages, delete messages that are spam, or allow delivery of messages that were improperly tagged.

Logging In

The web interface for spam filtering is located at:

or https://scrubber.dca.net/ securely, however you must accept the self-signed certificate.

Your login is your e-mail address. If you do not have or do not remember your password, put your e-mail address in the login field and click "create new password." A new password will be e-mailed to your e-mail address.

If you use Microsoft Outlook as your mail client, a plugin can be downloaded from the login page. It will allow you to train the Firewall by classifying email as spam directly from your Outlook program.

Quarantine Options

When you login you see your quarantine inbox. This has all of the messages that were quarantined by our spam filter. You can click on the messages to read them in your web browser.
