SpamSieve 3.3 is a free update for those who have already purchased the SpamSieve 3.0 upgrade. If you’re using SpamSieve 2 and haven’t upgraded yet, the easiest way is to first let SpamSieve install the new version. At launch, it will show the Purchase window, and you can click the Check Upgrade Options button to get the upgrade discount without having to enter your old serial number.
Normally, SpamSieve will automatically offer to update you to the new version. There are also instructions for updating on this page. SpamSieve 3.3 is compatible with macOS 10.13 (High Sierra) through macOS Tahoe 26 and is recommended for all customers using those versions of macOS. Older versions are also available for macOS 10.12 (Sierra) and earlier.
The changes in this version are:
- Made various changes to improve SpamSieve’s filtering accuracy.
- When searching in the Corpus or Log window, you can now choose the search scope. This enables faster and more targeted searching. Additionally, you can now search by Raw Message Source and by Words, which were not possible before. These can be especially useful in finding messages that were not correctly trained—you can then fix them to improve SpamSieve’s filtering accuracy. The new Searching section of the manual explains the different ways of searching and when they might be useful. Each search field now has a Search Syntax Reference menu item to quickly open this section of the help.
- Optimized’s SpamSieve’s message processing speed.
- Improved SpamSieve’s recognition of headers from server spam filters.
- Added the Fixing Uncorrected Mistakes section of the manual.
- Improved the following sections of the manual:
- Searching by message identifier now works when there’s extraneous whitespace.
- Improved the error reporting for Apple Mail remote training.
- Added a workaround for App Nap pausing filtering.
- Fixed a crash that could occur during a software update.
- Fixed a bug that could cause SpamSieve to show its Settings window when it was being launched by Apple Mail or Outlook.
- Fixed some crashes that could be caused by regex processing with invalid UTF-8.
- Fixed a bug where recent searches were not shown in the menu until after the first search.
- We need help updating SpamSieve’s Japanese localization. If you’re interested, please contact spamsieve@c-command.com.
