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.

Wake On Demand in Snow Leopard
Putting your Mac to sleep saves power, but it also disrupts using your Mac as a file server, among other purposes. Wake on Demand in Snow Leopard works in conjunction with an Apple base station to continue announcing Bonjour services that the sleeping computer offers.
While the requirements for this feature are complex, eligible users can toggle this feature in the Energy Saver preference pane. It's labeled Wake on Network Access for computers that can be roused either via Wi-Fi or Ethernet; Wake on Ethernet Network Access or Wake on AirPort Network Access for wired- or wireless-only machines, respectively.
