SpamSieve has been updated to version 2.6.6. This is a free update that includes the following enhancements:

• Made various accuracy improvements.
• Rewrote internal corpus storage to work around a performance bug in Mac OS X 10.5 that could, in some circumstances, make SpamSieve very slow to launch.
• Worked around a problem on Mac OS X 10.5 where the Apple Mail plug-in would sometimes try to launch multiple copies of SpamSieve (and then they’d all self-quit, leading to -609 errors).
• Made some internal changes so that Use Growl global notification system works more reliably on Mac OS X 10.5.
• The Flash PowerMate notification feature now works with version 2.1 of the PowerMate software.
• If SpamSieve’s corpus file or history database is damaged, you can now hold down the Command and Option keys at launch to reset them.
• Growl notifications are now posted from a background thread, to speed up message filtering.
• Fixed bug where the open panel for the Import Addresses… command was slow.
• Worked around a problem that could cause corruption of SpamSieve’s Entourage scripts.
• Fixed rare crash when processing HTML messages.
• If SpamSieve is unable to install its Apple Mail plug-in, it now does a better job of helping you complete the installation manually.
• Integration with Apple Mail and Entourage no longer relies on the mydefaults command-line tool, since it had some limitations and there were occasional problems installing it.
• The software updater is better at handling invalid downloads folders.
• Added Dutch localization and updated the other localizations.
