How to Enable Spotlight Indexing in Postbox
To enable Spotlight indexing of email in Postbox, go to Preferences | General and check "Allow Spotlight to to search messages". To immediately get all your mail into Spotlight, do Tools | Indexing | Index All Messages...
Index Trash or Junk Messages
By default, Spotlight will not index any messages in your Trash folders, Junk folders, or messages marked as Junk.
To enable Spotlight indexing of messages in your Trash folders, use the Config Editor and set the hidden pref mail.spotlight.ignore_trash to false.
To enable Spotlight indexing of messages in your Junk folders and message marked as Junk, use the Config Editor and set the hidden pref mail.spotlight.ignore_junk to false.
Search by Topic
Postbox allows you to use Spotlight to search for Postbox messages by Topic. For example, you type the following into the Finder search bar: "keyword:marketing" to find all messages that have the Topic "marketing." You can then create a Saved Search and save it to your Finder sidebar.
- Unchecking "Allow Spotlight to to search messages" can temporarily cause Postbox to "beach ball" (hang) while Postbox removes all messages from Spotlight.
- Spotlight integration does not work with multiple Postbox profiles.
