How to Use Spotlight to Search for Messages 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.

To enable this functionality please perform the following steps:

  • Make sure the Postbox app resides in Applications folder on your Mac.
  • In Postbox, under Preferences > General check the "Allow Spotlight to search messages" option.
  • Make sure that only ONE copy of Postbox is on your hard drive or any mountable volume.  Use Spotlight to search for "Postbox" with Kind: Application to find any and all copies of the Postbox application.  If you have partitioned your drive to manage more than OS X installs, only ONE copy of Postbox can exist (otherwise Spotlight might use the wrong importer).
  • You must re-index your mail messages by going to Tools > Indexing > Index All Folders... You may wish to perform this last step overnight to avoid work interruptions.
