Address Books

Learn how to setup your address books and import contacts.

Back to introduction


Postbox provides full read and write integration with the Mac OS X "Contacts" application, so users can now keep all of their contacts in one location.

Setting Up

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.

Within Postbox, check to make sure this setting is enabled:

  • Navigate to the Postbox Window menu and select Address Book.
  • Then go to the File menu and ensure that Use Mac OS X Address Book is enabled.

Contacts Integration

By default, new cards will be created in the Mac OS X "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.

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 toPostbox > Preferences > Composition > Addressing and de-select "Local Address Books."


To build your Postbox Address Book, you can start by importing your address book databases from other clients. Postbox will accept .csf, .tab, .txt and LDAP files. Go to Tools > Import... to get started.

Using the Address Books

To open the Postbox Address book, click the toolbar button, or go to Tools > Address Book (Windows) or Window > Address Book (macOS).

Address Book Groups and Lists

When you open the Address Book for the first time, you'll see two or three groups in the sidebar:

  • Personal Address Book - Default group for Windows users.
  • Mac OS X Address Book (Mac only) - Shows the macOS Address Book.
  • Collected Addresses - Automatically saved addresses from sent/received messages. 

Lists (also known as Distribution Lists) are sub-collections of your Address Book Groups which allow you to easily and repeatedly send messages to multiple recipients. You can create lists within the Personal Address Book or Collected Addresses. Then, to populate the lists with the correct contacts, drag and drop them from the main collection to the specific list in the sidebar.

For macOS users, any changes you wish to make to Lists should be performed in the macOS Contacts app. Any changes will automatically be updated in Postbox.

Managing Contacts

Within the Address Book, you can create new contacts by clicking the New Card button in the toolbar, and fill in the information into the appropriate fields.

Alternatively, if you're viewing a message, you can add the sender to your Address Book by clicking the sender's name, and clicking add contact in the Contacts Card. If the sender is already in the Address Book, you can click edit... to make changes to the contact. 

To change how your contacts are displayed, go to View > Show Name As, and choose between "First, Last", "Last, First", or "Display Name". You can also change how they're sorted by going to the View | Sort By menu.


You can export your Postbox Address Book by using the export tool. Select the group or contact(s) that you wish to export, go to Tools > Export..., choose the export location, and decide between LDAP, Comma Separated or Tab Delimited file formats.
