Guidelines for using the CSU Spam filtering tools
What is the CSU Spam Filter Tool?
The CSU Spam Filter Tool is a mail-filtering program that runs on the CSU email servers. All ingoing and outgoing CSU email messages pass through the CSU Spam Filter Tool. The CSU Spam Filter Tool looks for certain Spam-like message characteristics and performs actions on the message when these characteristics are found.
How Does the CSU Spam Filter Tool Identify Spam?
The CSU Spam Filter Tool contains several hundred spam tests that analyze individual characteristics of each email message. Each of these tests has a numerical weight. When a message is analyzed by the CSU Spam Filter Tool, the weights from all the spam tests that matched the message are added up and converted to a spam score that expresses the message's "spam probability". This probability will be listed in the Subject Heading of the email, similar to the example below.
Example - [Suspect Spam:24%] Win a holiday to Fiji!!!
By default, the CSU Spam Filter Tool only checks for spam in messages that originate from outside the network, not in messages that originate within the CSU domain. If a message is found to have a spam probability of 50% or more, it is copied to the CSU Spam Filter Tool Quarantine. By default, the CSU Spam Filter Tool also delivers a message to your inbox letting you know what messages have been blocked.

The CSU Spam Filter Tool End User Web Interface
The End User Web Interface (EUWI) gives the CSU Spam Filter Tool users access to email-filtering features. Users can view and manage messages that are quarantined (blocked) by the CSU Spam Filter Tool, manage user-specific sender lists, and configure various email-filtering options.
To login to the CSU Spam Filter Tool, go to http://quarantine.csu.edu.au:28080/index.cgi, enter your CSU User name and Password.

The EUWI is comprised of the following components:
- Navigation Menu: The menu located on the left side of the page.
- Main Page: The current page accessed through the navigation menu. Links to additional pages include: Blocked Messages, Deleted Messages, Blocked Senders, and Options.
- Email Message Viewer: A viewer that opens when a message's "Subject" link is clicked.

Blocked Messages
The Blocked Messages page displays all email messages that are quarantined by the CSU Spam Filter Tool due to spam content. Using the Blocked Messages page, you can:
- view blocked messages
- Quarantine and deliver them to your mailbox
- delete and send messages to the Deleted Messages page
- deliver to a sender
- delete all messages in the list
You can sort quarantined messages based on the spam Score, the email address listed in the From header, the message's Subject, or the Date the message was delivered. Note that the date column displays the time in hours and minutes for messages blocked in the last 24 hours. Both the time and date are shown for messages blocked more than 24 hours ago.
