Gmail has this feature where appending a plus ("+") sign or a dot to an email address will still have it sent to the same address. This makes it easier to filter emails sent to you, by checking which email address the email was sent to and then label, star or auto-delete emails based on that.
Yahoo! mail also has a similar feature: Address Guard, which uses the dash ("-") sign.
Does Hotmail or Outlook.com have a similar feature? If yes, how does it work?
