The Private Post Line-Up
Our goal is to encrypt the email from every PC on the planet. To do this we address both ends of the global email eco system. The worldwide email infrastructure is provided by hardware and software makers. Users access their email via a number of different email clients and, as you can see from our downloads page, we either currently do or will support email clients that operate on the following platforms: Microsoft Windows XP, Mac OS X and Linux.
