C-Command Software has released SpamSieve 2.9.6 with a fix for a bug that slowed down spam-filtering operations in Postbox when running OS X 10.8.2 Mountain Lion. The update now understands that @icloud.com, @me.com, and @mac.com addresses are equivalent for training purposes in Apple Mail, and SpamSieve also offers to load addresses from Microsoft Outlook directly rather than use the less-than-reliable Sync Services to perform that task. The release also removes flags from a message trained as good in Apple Mail, improves handling of invalid data received from a mail program, and improves interaction between SpamSieve and server-based spam mailboxes to prevent a trained spam message from ending up in the local spam mailbox.

Two Shortcuts for App Exposé
If you want to see all the windows for a particular app via App Exposé, there are two hidden shortcuts. For either, start by pressing Command-Tab to bring up the app switcher. Then, while still holding down the Command key, press either the 1 key or the up arrow. That puts you into App Expose mode, with all of an app's windows showing, and recent documents in a row across the bottom of the screen. Let up on the Command key, and then you can press Tab to cycle through all the running apps.
