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 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.
