How to unlink the callto: handler for Phone Numbers

If you would rather not have phone numbers in messages linked to the callto: handler (which in turn will use apps like Skype to dial), please follow these instructions:

  • Go to Options | Preferences > Advanced > General > Config Editor
  • Type in: mail.datapane.detectors.phone_numbers 
  • Double-click that entry to turn it into "False".
  • Restart Postbox and those phone numbers will no longer be linked.
