Version 1.1 of SpamSieve is now available.

This is a free update that includes the following changes:

• E-Mail Client Integration
  • Added support for PowerMail.
  • Added instructions and an AppleScript for making Mailsmith download and filter mail faster.
  • Added an AppleScript for Entourage that moves spam into a Junk folder.
• Performance
  • Launches about 60% faster than 1.0.
  • You can now prune the corpus to remove words that are taking up memory without contributing to spam recognition. This can also dramatically decrease SpamSieve’s launch time.
  • Recalculating spam probabilities is about 10% faster and uses less memory.
  • Quitting is faster because SpamSieve now writes corpus changes to disk during idle time.
  • Saving the corpus is slightly faster.
• Displays statistics about the number of messages filtered, SpamSieve’s accuracy, and the types of words in the corpus.
• SpamAssassin’s X-Spam-Status headers are now treated as single words. This means that if SpamAssassin is running on your mail server, SpamSieve will learn to respect (or ignore) its judgment.
• Does a better job of ignoring e-mail attachments, thus reducing corpus bloat.
• Installs the eSellerate Engine if it’s not present, thus enabling “Instant Registration” for more users.
• Asking SpamSieve to categorize a message now forces an update of all the word probabilities. Previously, the update only happened during idle time.
• Highlights the sorted column in the Corpus window. The columns themselves have shorter names. There’s a new “Total” column. Auto-resizing of the columns works better. You can now manually resize any column, and manual resizings and reorderings are saved between launches.
• Shows fatal errors as alert panels rather than just printing them on the console.
• The Corpus.plist data file is now sorted by word. This makes it easier to examine the corpus manually, and to compare it to other users’ corpora.
