Light weight e-mail client with GTK+

 Sylpheed is an e-mail client which aims for:
  * Quick response
  * Graceful, and sophisticated interface
  * Easy configuration, intuitive operation
  * Abundant features
 The appearance and interface are similar to some popular e-mail clients for
 Windows, such as Outlook Express or so.
 The interface is also designed to emulate the mailers on Emacsen, and almost
 all commands are accessible with the keyboard.
