C-Comand Software released an update to SpamSieve Thursday, bringing the spam filtering software to version 2.8.1. The update includes several bug fixes and many improvements to the software.

Changes included in the patch notes:

• Fixed a regression in the SQLite build that could cause SpamSieve to crash when running on a PowerPC-based Mac.
• Made various changes to improve SpamSieve’s filtering accuracy.
• Adjusted the SpamSieve - Train as Good command in Apple Mail to reduce confusion. Training a message as good now will only move the message into the inbox of an enabled account. If no account matches the message or if the proper account is disabled, it will move the message into the inbox of the first enabled account (even if it doesn’t match). Thus, the message will always move out of the Spam mailbox, and it will no longer seem to disappear because it was moved into an inbox that was hidden.
• Made various code modernizations.
• Apple Mail now auto-launches SpamSieve sooner, to speed up the filtering of the first messages.
• Improved the support for server-side Spam mailboxes in Apple Mail.
• Clarified the instructions in the Do an Initial Training section of the manual.
• Added the How do I make SpamSieve catch spams sent from my own address? section to the manual.
• Expanded the Correct All Mistakes section of the manual.
• Improved the Apple Mail troubleshooting instructions.
• Improved the styling of the Apple Help.
• Improved SpamSieve’s launching speed.
• Fixed a bug where, in rare circumstances, SpamSieve didn’t filter all of the first batch of messages when using Apple Mail on Mac OS X 10.6.
• SpamSieve will now warn you if it looks like its Apple Mail plug-in has been damaged by an application slimming utility. This could lead to Mail continually reporting that the plug-in was incompatible.
• SpamSieve will now complain if it looks like you’ve manually installed the Apple Mail plug-in in the wrong folder instead of using SpamSieve’s installer.
• Made a change to try to work around a bug in Apple Mail that could make training a message as good create a duplicate copy of the message.
• Improved the Purchase window to reduce confusion about the demo period, serial numbers, and the number of seats that you’ve purchased.
• Modernized the Software Update window and code.
• Changed the way the Software Update feature finds the downloads folder on Mac OS X 10.5 and later because sometimes the one that Internet Config returned would be invalid or unwanted.
• Fixed a bug where SpamSieve would crash when processing certain invalid URLs.
• Fixed an error where a newly added whitelist/blocklist rule might not be auto-selected.
• Removed the Dutch, Italian, and Portuguese localizations because they were out of date. If you would like to update the translation for one of these languages, please contact spamsieve@c-command.com.

The update is free to registered users of previous versions of the software. The full version is priced at US$30.
