Email Settings for iCloud, .Me or .Mac


When your Apple ID is protected with two-step verification, you'll need an app-specific password to sign in to your email account.

Step 1: Turn On Two-Factor Authentication / Generate an App-Specific Password

  1. Login at iCloud online
  2. In the Security section, turn on Two-Factor Authentication.
  3. Under the App-Specific Passwords section, click Generate Password.
  4. Enter a label, such as "Postbox." 
  5. Copy the password that is provided. You'll need it later!
IMPORTANT: The app-specific password will be in the following exact format: xxxx-xxxx-xxxx-xxxx, for example, dksi-umcn-pqcz-kdit. If your password does not have this format, you are most likely using your iCloud password, which will not work for your email account. Please use an app-specific password.

Step 2: Use the New Password within Postbox

  1. First, we need to ensure that an existing password doesn't exist. In Postbox, go to Preferences > Security > Passwords > Saved Passwords. If you see incoming and outgoing servers for your iCloud account listed here, select each and click the Remove button. Then restart Postbox. 
  2. Enter your new Apple App-Specific Passwords when prompted for both incoming and outgoing servers.
    NOTE: You'll need to send a message from the account to trigger the password prompt for the outgoing server.

Please see Using App-Specific Passwords for more information or visit Apple Support.
