Version 2.1.1 of SpamSieve is now available.

This is a free update that includes the following changes:

• Much faster at processing messages when there are many blocklist and whitelist rules. Also improved the speed of loading, deleting, and sorting rules.
• Improved accuracy tracking with the Panther version of Apple Mail; previously, SpamSieve couldn’t always tell when it was being corrected.
• Catches more spam because it knows about more spammer obfuscation tricks and also which headers it should ignore.
• Fixed bug (introduced in 2.0) where the Bayesian engine didn’t work if Mac OS X’s default language was set to Japanese.
• The SpamSieve Eudora Plug-In is better at launching the SpamSieve application if it is not already running.
• Loading Entourage addresses now adds to the addresses that were previously loaded, rather than replacing them. This makes it possible for Entourage users who have more than one Entourage identity to give SpamSieve the addresses from all their address books (by loading once for each identity). Hold down Option when clicking Load to get the old behavior of replacing the previously loaded addresses.
• The sound pop-up menu in the Preferences window now immediately notices when new sounds are installed; previously, it would only check when updating the rest of the preferences window.
• You can now add a rule without a the Blocklist or Whitelist window being frontmost. SpamSieve will ask which type of rule to add.
• Regex rules can now start with an options modifier such as (?-i).
• Copying rules to the clipboard now just copies the text to match (typically an e-mail address), not all the columns. To get all the columns, you can print to PDF.
• The Entourage Add Good script now finds localized inboxes, rather than creating a folder called Inbox.
• The Entourage Add Spam script can now remove spam messages from the server.
• The Statistics window now shows percentages instead of ratios.
• SpamSieve will now quit at launch if another copy of the application is already running.
• Re-targeted broken Habeas URL.
• Added the following menu commands: Close All Windows, Minimize All Windows, and Zoom.
