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.

Mac OS X Services in Snow Leopard
Mac OS X Services let one application supply its powers to another; for example, a Grab service helps TextEdit paste a screenshot into a document. Most users either don't know that Services exist, because they're in an obscure hierarchical menu (ApplicationName > Services), or they mostly don't use them because there are so many of them.
Snow Leopard makes it easier for the uninitiated to utilize this feature; only services appropriate to the current context appear. And in addition to the hierarchical menu, services are discoverable as custom contextual menu items - Control-click in a TextEdit document to access the Grab service, for instance.
In addition, the revamped Keyboard preference pane lets you manage services for the first time ever. You can enable and disable them, and even change their keyboard shortcuts.
