Using the Do Not Spam List to Reduce Spam

Email from known spam sources is blocked so that it never appears in your mailbox. This service uses published lists from a vendor to identify such mail, which is then blocked. Blocked mail is rejected and not accepted for delivery. You can turn off use of the Do Not Spam List if you wish, but we do not recommend that.

How the Do Not Spam List Works

ITS uses several spam-blocking lists for its Do Not Spam List service to reduce unwanted email for your

Individual email: All mail addressed to (where youruniqname has been replaced with your own uniqname) checked against the list.

Group email: Groups in the MCommunity Directory (with addresses in the form of, where groupname has been replaced with the actual name of the group) checked against the list.

If a message is from an IP (Internet Protocol) address included in the Do Not Spam List, that message is rejected (not accepted for delivery). This helps to eliminate much of your spam mail. The Do Not Spam List includes IP (Internet Protocol) addresses of known spammers, addresses of machines that should not be sending email, and so on.

The Do Not Spam List Is On Automatically

The Do Not Spam List is turned on automatically for all new members of the university community when their MCommunity Directory profile is created for them. It is also turned on for all new MCommunity groups.
