How To Increase Delay Before Postbox Starts Indexing On Idle

By default, Postbox waits for five minutes (300 seconds) of idle before indexing.  To increase the delay before idle indexing:

  • Open Config Editor.
  • Paste mail.fulltextsearch.idle_time into the "Filter" field.
  • Double-click on the that row for mail.fulltextsearch.idle_time 
  • Change the value from 300 to a larger value.
  • Restart Postbox.
