Spam Sleuth includes our InstantX technology which gives you the ability to download updates over the Internet. First open the Mail Jail by double-clicking on the Spam Sleuth icon in your Windows System tray next to the clock. Choose Help > Update > Update Now!
You can have Spam Sleuth check for updates every time it runs, once a day, or once a week. From the menu select Help -> Update -> Settings -> InstantUpdate tab. Then you can specify how frequently to check for updates. We recommend once a day or once every seven days. If you don't want Spam Sleuth to update at all, just set to Manual Update Only.
