You’ve got to hand it to him: Michael Tsai keeps a good thing going.

Michael Tsai’s must-have shareware program, SpamSieve, has just been updated to version 2.9.5. The new version, a 10 megabyte download, adds the following fixes and improvements:

- Updated the Apple Mail plug-in to work with Security Update 2012-004 (Snow Leopard) for Mac OS X 10.6.8. If, after installing this update, you don’t see the SpamSieve commands in Mail’s Message menu, it may be necessary to go to the SpamSieve menu and choose Install Apple Mail Plug-In.

- The AppleScripts for controlling the Griffin PowerMate seem to trigger a crashing bug in OS X 10.8 Mountain Lion. Thus, SpamSieve’s Flash PowerMate option has been turned off. You can try re-enabling it in the preferences if desired.

- When training a message as good from Apple Mail, SpamSieve is better at figuring out which account it came from.

- Worked around problems on some Macs that could prevent SpamSieve from receiving training commands from Apple Mail on OS X 10.8 Mountain Lion.

- Import Blocklist Regex Rules is a sample AppleScript that shows how to create blocklist rules using the contents of a text file.

- Made various improvements to the manual.

SpamSieve retails for US$30.00 and requires Mac OS X 10.4 or later to install and run.
