C-Command Software has released SpamSieve 2.9.8 with a variety of improvements to the app’s filtering accuracy and a change to the Train as Good command in Apple Mail, which now considers the message’s CC recipients when determining the correct destination inbox. The spam-filtering utility has been updated to handle the recently released OS X 10.8.5 Mountain Lion (see “OS X 10.8.5 Fixes Nasty Text Rendering Bug,” 12 September 2013), but not the upcoming OS X 10.9 Mavericks. The release also improves how the installer works around incorrect Apple Mail folder permissions, removes unused code from the Apple Mail plug-in, and updates several sections of the manual.

Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
