Installing Dictionaries in Other Languages

Instructions for Windows

  • Download and save the dictionary to your hard drive. (Firefox users, be sure to right-click the download link, then select "Save Link As..." from the contextual menu.)
  • In Postbox, go to Tools | Add-ons.
  • Click the Install button and select the file you downloaded and click "OK".
  • Restart Postbox and then go to Preferences (Tools | Options on Windows) / Composition / Spelling and select your default dictionary.

Information for macOS

Postbox uses the macOS system dictionary service and the dictionaries installed on your system. To change the dictionary, go to Preferences | Composition | Spelling and select your desired default dictionary. You can also change this from the Spell check toolbar button in the compose window.

Mozilla dictionaries cannot be installed in Postbox for Mac.
