Michael Tsai’s must-have shareware program, SpamSieve, has just been updated to version 2.8.6. The new version, an 8.3 megabyte download, makes the following fixes and improvements:

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

- Improved compatibility with Mac OS X 10.7 (Lion).

- Added support for Postbox 2.5.

- Updated the Setting Up MailMate instructions for the new preferences in MailMate 1.1.2.

- Updated the Setting Up Outlook instructions for Microsoft Office 2011 Service Pack 1.

- Updated the Setting Up Postbox instructions to ensure that messages that you train as spam are moved to the junk mailbox or trash.

- Worked around a rare OS/hardware condition that could prevent SpamSieve from launching.

- The Apple Mail plug-in is better at reporting errors when it’s unable to fully load itself.

- Made various other clarifications to the manual.

- Adjusted the help page titles to fit better in the menu and search results.

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.
