A new way to manage SPAM email

Recently, college employees have been the recipients of misleading and unwanted email messages from miscellaneous sources on the Internet. The content of these email messages is often undesirable or pornographic in nature. Unsolicited email messages broadcast to entire Internet communities are commonly referred to as SPAM.

Your ITS team is implementing an anti-spam filter that will attempt to identify and tag SPAM email.  This filter uses a preprogrammed set of criteria to preview email messages.  Suspect messages are tagged with the phrase *** POTENTIAL SPAM *** in the subject line of the message. Actual message content is not modified.

The following criteria are generally used to identify SPAM, although the filter uses a complex and sophisticated algorithm:

* Frequency of certain key words within the message
* Domain or site used to send the message (known SPAM sites)
* Invalid header format of email message (sender unknown etc)
* Extraordinarily large number of recipients

There is a possibility that some legitimate email will be tagged as SPAM. If you receive mail that has been incorrectly identified as spam, please contact the ITS Help Desk.  This will enable us to modify the filter, preventing accidental labeling of future messages.

To further assist you with managing SPAM, GroupWise rules can be setup that will automatically delete, or move to a folder, all ***POTENTIAL SPAM*** labeled email. You may want to assess the performance of the SPAM filter on your messages before setting up a rule for automatic deletion. This will prevent the unintended loss of legitimate email. 

The ITS Help Desk can assist you with setting up rules, or find additional information on rules at the ITS website http://www.cpcc.edu/ITservices
