Postbox for Mac OS X v1.0 Beta 15

A new kind of messaging application, the Postbox™ email client helps you spend less time managing email and more time using email to get things done. Postbox automatically analyzes your e-mail messages, documents, photos, and links to web pages; then it catalogs all this information making it faster to search for and retrieve.

Easy-to-use tagging features let you organize messages the way you want and then focus on one project at a time without missing out on important new messages. You can also view messages by conversation, edit messages, and create to-do items that appear in mailbox windows.
