Needless to say, the cut down version has the same look and feel but just lacks some of the functionality of the full blown version.
Both Postbox and Postbox Express seem to have been derived from Thunderbird. Some of the features in both pieces of software are found in Thunderbird as well but not in most other email software.

Email threading where you can see all the emails in a given thread is great (and not available in all email packages).
‘Post’ is a button which lets you post to Twitter, Facebook and Friendfeed from inside Postbox Express. If you want to share something quickly but not have to switch into a browser and end up being distracted by your friends status updates, this gives you a small dialogue box so you can say it quickly and move on.
‘Topics’ is another useful feature. By assigning a topic to an email (or the other way round if you prefer to think of it that way), you can quickly separate work email from home email, or urgent email from non-urgent email. And, having got your mind round the idea, you can allocate Topics retrospectively, so you can assign them individually or using filters.
One of the features started in the Firefox browser is found in Postbox Express having come to it via Thunderbird – tabs. Displaying different emails on different tabs makes life so much easier if you need to refer to several emails at once.
Postbox Express for Mac
The installation is completely standard Mac – simply drag Postbox Express into the Applications folder. You can choose to let spotlight search within Postbox Express, and to link Postbox Express to iCal, iPhoto, Safari, Dictionary or other Mac apps. You can also drag and drop files on top of the Postbox dock icon in order to create a new message with that item as an attachment which is great.
Postbox Express for Windows
The only real difference between the Mac version and the Windows version is in design. Mac has slick black pop-ups, whereas Windows has shiny grey.
