Spam Screening at MITOverviewUsers of MIT email have the option of screening incoming messages for spam. MIT Spam Screening performs a series of tests on an incoming email message, scores it as spam or not according to a set of criteria. Once mail is identified as spam, it can be filtered to avoid cluttering your inbox. For IMAP mail clients, filtering is handled automatically once you create a Spamscreen folder on the mail server. With POP clients, you must configure your client to filter messages based on the spam flag in the headers. Spam Scoring and FilteringAll email that is currently received in your MIT account (ending in @mit.edu) is given a spam ranking score. Messages that have a certain score or higher are considered spam and are marked as such in the message headers. You can adjust your threshold with Personalized Settings. Once email is marked as spam, it can be kept out of your inbox by filtering. Using IMAP (recommended), filtering is automatic once you create a Spamscreen folder on the mail server. Mail identified as spam will be placed in the Spamscreen folder. As filtering is handled entirely on the server, you only have to configure it once to work with all IMAP email clients. With POP, you must configure your email client to search for the spam flag in the headers and filter it to a local folder. If you have multiple machines/clients you will need to configure each one for spam filtering. ConfigureIMAP (recommended): Screening and filtering takes place on the server.
POP: Filtering takes place locally. You will need to set up spam filtering on each local client you use.

MIT ImplementationMIT Spam Screening uses SpamAssassin
on the MIT email servers to lessen the impact on the MIT community
of the increased volume in spam messages. Enabling this product
decreases the amount of spam you receive but cannot eliminate it
entirely. Last modified: 03/04/2008 |
