Spam and Virus Filtering

Spam and Virus Filtering with PureMessage
on Cornell's Central Mail Servers

CIT uses a tool called PureMessage to help keep unwanted messages out of your e-mail's Inbox. PureMessage does three things:

• It prevents virus-infected e-mail from reaching your computer.
• It looks for spam-like characteristics in all messages and for each message, assigns a probability that the message is spam.
• Based on that probability, it either:

• Deletes the message (probability greater than 80%)
• Delivers the message (probability less than 80%)
