I have to admit I am an email junkie. I rely on my email client for keeping up with my work as well as my personal life. From my email client I require speed, power, and flexibility. When you think about email in Linux you think of three main players: Thunderbird, Evolution, and KMail. But there is a fourth player in the game, one that is as powerful, faster, and as user-friendly as all of the competition. That client? Claws Mail.
