Spam Tagging

Spam Tagging

As part of the UCR e-mail system, Computing and Communications has deployed a spam detection and tagging system. Because spam sending techniques have become more sophisticated over time, staying a step ahead of spammers has required a continual evolution of anti-spam products to safeguard our systems. Our current spam tagging system causes a high percentage of spam messages to be identified and tagged as such. It accomplishes this by checking all incoming mail and rating each one with a number. When the number reaches a certain threshold, a separate header tag will be inserted into the e-mail. This tag makes it easy to automatically move those messages to a spam folder by using the filtering capabilities of your favorite e-mail program.

In addition to email client filtering, filtering spam messages can also be done at the server-level by using the filtering capabilities of the Microsoft Exchange system. If this server-level filtering is used, it will be sent into a Junk Mail folder on the e-mail server in your account.

The Microsoft Exchange system includes a feature in the OWA interface whereby you can establish “Safe Sender Lists” of those e-mail addresses or domains you always want to receive in your inbox, even if the system thinks it is Spam. In Exchange, you can also create “Block Lists” of those e-mail addresses or domains you never want sent through to you, even if the system does not tag it as spam.

See the links in the menu at left for instructions on setting up email filters and your Safe Senders (Allow) Lists and Block Lists.
