C-Command Software has released SpamSieve 2.9 to address a bevy of maintenance issues. This update improves the spam-filtering software’s training regimen for “good” Exchange messages in Apple Mail as well as handling of incoming messages in Microsoft Outlook. The release adds support for Growl notifications via GNTP and support for training messages as spam via the Herald notification plug-in. Other changes include adding a new auto-training parameter in the score script that can override the setting in preferences on a case-by-case basis, modifying the mailbox moving behavior of the Change Settings command in Apple Mail, and adjusting drone AppleScripts for better troubleshooting. SpamSieve is also now code-signed for compliance with OS X 10.8 Mountain Lion’s Gatekeeper security feature. The update is rounded out by improvements in handling errors and fixes to other bugs.

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.
