Postbox provides read and write integration with the macOS "Contacts" application, so Mac users can now keep all of their contacts in one location.
By default, new cards will be created in the macOS "Contacts" application. When reading a message from someone not in Contacts, click on the Contact in the message header envelope and click add contact from the Contact Panel. This contact will be added to your Contacts app. Click on the contact again and click edit to open the Contacts app and edit the card. Photos added to the Contacts app will appear in Postbox as well.
Here's how to get things set up:
1) Enable Contacts App in macOS
Permission must be given to Postbox to use your Contacts app. If you are unable to access your contacts within Postbox:
- Open System Preferences > Security & Privacy > Privacy.
- Within the panel on the left, scroll to the Contacts application and select it.
- Within the apps panel on the right, scroll to Postbox and make sure that it is selected.
2) Enable Contacts App in Postbox
By default, Postbox will attempt to use the macOS Contacts app, but if the integration isn't working for you, check to make sure this setting is enabled:
- Go to the Window menu and select Address Book.
- Go to the File menu and toggle "Use macOS Address Book" one or two times until it is selected.
How To Prevent Postbox from Matching Local Addresses
If you use a Directory Server and don't want Postbox to suggest matches from your local address book, go to Postbox > Preferences > Composition > Addressing and de-select "Local Address Books."
Contacts within the macOS Contacts app cannot be modified within the Postbox Address Book. They must be modified within macOS Contacts app.
