Postbox is a powerful application that aims to provide you with all the tools for keeping in touch with your friends and business partners. It can handle multiple email accounts and allows you to subscribe to RSS feeds in order to read the latest news. The program is based on the popular Mozilla Thunderbird email client and its interface features the popular accounts, folders and messages panels for easy access. The message pane allows you to view the content of the current email which can also be opened in a new tab. Configuring the email accounts enables the user to only enter the email address and the password. The wizard automatically searches for the server configurations in the database and fills in the rest of the details if they are available which allows Gmail or Yahoo! users to add a new account in a matter of seconds. The Gmail integration allows you to organize your messages with labels and to navigate through the messages by using native Gmail shortcuts. You can also use the conversation view in order to group the messages when you need to follow a certain discussion.
