Postbox is a new desktop email client that helps you make the most of your email, offering powerful new ways to find, use, and view email messages and content, organize your work life, and get stuff done. Postbox works behind the scenes to catalog everything in your email. We mean everything: every bit of text, every contact, address and link.
Every picture, document and attachment. It’s all in the catalog and it’s all searchable. You can easily share the highlighted text on Twitter, Facebook or FriendFeed; or search on a variety of search engines and Wikipedia.
