SpamSieve

SpamSieve is a robust spam filter for major email clients that uses powerful Bayesian spam filtering.

SpamSieve understands what your spam looks like in order to block it all, but also learns what your legitimate messages look like to avoid confusion. SpamSieve only marks spam in your email client so you never lose any mail.

Note: Now requires OS X 10.7 or later running on a 64-bit Intel processor

• Made various changes to improve SpamSieve’s filtering accuracy.
• Fixed a database bug that could cause SpamSieve to crash when processing a particular type of spam message containing garbage Unicode characters in the subject.
• Outlook - Filter Mailboxes now checks for new inbox messages every 1 minute by default (instead of 5), is more efficient, and is able to filter inboxes with localized names that were previously ignored.
• Updated the Requirements and Setting Up Postbox sections of the manual. Postbox 6 no longer supports plug-ins, so we recommend continuing to use Postbox 5 for the time being or using the Apple Mail drone setup in the background.
• The Outlook sections of the manual have been renamed to Setting Up Outlook 365 and Setting Up Outlook 2011 for clarity.
• Improved the following sections of the manual:
  • Automatically Deleting Old Spam Messages
  • Checking the Apple Mail Setup

  • Using a Spam Mailbox on the Server
• Worked around a bug in macOS 10.13 that could cause an internal error at launch when resolving an alias.
• The Apple Mail - Discard Spam script is better able to work around Mail slowness that could leave spam messages stranded in the trash.
• Diagnostic reports now include more information about localizations and SpamSieve helper processes.
• Made various minor code updates.
