SpamSieve 3.3

C-Command Software has published SpamSieve 3.3 with many changes to improve filtering accuracy. To improve search speed (and provide a more targeted search), the update now enables you to choose the search scope, enabling you to select from Subject, From, To, Matching Words, and other filters. You can also search by Raw Message Source and by Words, which can help find messages that were not correctly trained (see the new Searching section of the manual for more details).

The spam-filtering utility also optimizes SpamSieve’s message processing speed, improves SpamSieve’s recognition of headers from server spam filters, ensures searching by message identifier now works when there’s extraneous whitespace, improves error reporting for Apple Mail remote training, adds a workaround for App Nap pausing filtering, fixes a bug that could cause SpamSieve to show its Settings window when it was being launched by Apple Mail or Outlook, and resolves an issue where recent searches were not shown in the menu until after the first search.
