Proofpoint is an anti-spam product that acts as a gatekeeper for TTS' email servers. The product inspects more than 200,000 message attributes and currently has a high degree of success at detecting spam. Once examined, legitimate messages are routed to the recipient's mailbox while suspected spam is quarantined by Proofpoint. Each morning Tufts email users will receive a personal digest consisting of one email that contains links to all the messages tagged as spam and quarantined over the past 24 hours. In the rare event that a message marked as spam is legitimate, the message can be released to your inbox with the click of a button. The digest can then be deleted like any other email.
