Michael Tsai’s must-have shareware program, SpamSieve, has just been updated to version 2.8.8. The new version, an 8.8 megabyte download, adds the following fixes and improvements:

- Improved compatibility with pre-release versions of Mac OS X.

- Added support for Postbox 3.0.

- Added support for Growl 1.3.

- Made various changes to improve SpamSieve’s filtering accuracy.

- The Exclude my addresses feature now lets you specify additional addresses via Terminal, if you don’t want to clutter your “Me” card in Address Book.

- The Apple Mail plug-in installer is more resilient to permissions errors.

- Added example of using colored flags to sort spam messages in Apple Mail by spamminess.

- Added some logging to detect obscure errors when loading SpamSieve’s Apple Mail plug-in.

- Improved the French localization.

SpamSieve is available for a US$30 registration fee and requires Mac OS X 10.4 or later to run. The new version can either be downloaded directly from the web site or brought up to the current version via the program’s built-in update feature.
