Due to the ever-increasing volume of spam email and resource demands and diminishing effectiveness of our prior solution, ITSS has bought a commercial anti-spam solution from Proofpoint. ITSS conducted extensive testing in December 2006 and found Proofpoint to be much better at reducing spam than our existing tools and it generated no false positives (legitimate messages that are mis-identified as spam). Based on this successful evaluation, Proofpoint protection will continue to be used for all U-Mail (und.nodak.edu) and GroupWise (mail.und.nodak.edu) email accounts.
Like the prior spam solution used by ITSS, Proofpoint works by "spam scoring" and then filtering messages according to how they have been scored. Any filters or rules that you have created to manage SPAM in your e-mail account should continue to work without changes. You can find out more about how spam scoring and filtering works, at http://www.und.edu/dept/itss/faq/umailantivirus.html.
If you have questions or concerns about Proofpoint, please contact the ITSS Help Desk at 701-777-2222 or email: itsshelp@mail.und.edu.
