Spam Scoring

Once a message has passed the initial LISSonline Spam Firewall block/accept filters, it is then scored for its spam probability. This score ranges from 0 (definitely not spam) to 9 or even greater (definitely spam). Based on this score, the LISSonline Spam Firewall can take one of four actions:

Allowed
Messages with a score below the tag threshold are sent to the intended recipient(s).
Tagged
Messages scoring equal to or greater than the tag threshold, but below the quarantine threshold are delivered to the sender. Tagged messages contain a subject line of the message with the text "[LISSonline] Spam:". The text provided is prepended to the subject line. 
Using "Rules" in applications such as Microsoft Outlook to move messages with "Spam:" in the subject to a Junk E-mail folder can reduce the messages that are delivered to the Inbox, as well as prevent forwarding to many mobile devices such as Blackberry's.
Quarantined (see Quarantine Inbox below)
Messages scoring equal to or greater than the quarantine threshold, but below the block threshold are quarantined. Messages are sent to a Per-User Quarantine Inbox.
Blocked
Messages scoring equal to or greater than the block threshold are not delivered to the recipient.

Quarantine Inbox

An e-mail is sent to each user who has items in their Quarantine Inbox daily at 3:35 pm by default.  At the bottom of this message is a link to that users Quarantine Inbox.  Users can Deliver, Whitelist, or Delete messages, as well as "Classify as Spam" or "Classify as Not Spam".  These classifications help to improve the accuracy of the LISSonline Spam Firewall over time.

Messages are automatically deleted from the Quarantine Inbox after 10 days.

Plug-Ins for Outlook

Microsoft Outlook Plugin Version 1 (Windows 95/98/2000/NT/XP)

Download from http://antispam.lissonline.com:8000
click the "Get Mail Client Plugins Here" link

Once installed, the plugin will allow classification of messages as spam or not-spam from the mail client. To use the plugin simply select the message(s) to be classified in Outlook and click on the red envelope ('X' mark) for spam, or the green envelope ('Check' mark) for not-spam.

Please keep in mind that marking messages may not yield immediate results.  Marking messages helps the system learn to better identify spam and detection will become better over time.
