  • Connection-time filtering has a view of the world of e-mail senders based on various sources of reputation, as well as recent trends in e-mail content. Sender reputation is largely tied to IP addresses or ranges of addresses.
  • Content filters run against incoming e-mail that can identify the e-mail as spam by analyzing the content.
  • Your preferences let you set up your own blocklist and safelist and rules, and we use all of that information to do additional filtering of spam.
  • Malware detection scan attachments and block those that contain known malware and viruses.
  • Tools in the Hotmail UI display a safety bar when you’re reading messages that warns you of potential danger based on the sender’s reputation.
  • Time-traveling filters “once we do identify a spammer we can go back and clean out spam that they’ve already sent to your Inbox before you ever see it. We call those tools time-traveling filters.”
