Claws Mail is a powerful and full-featured mail client formerly called Sylpheed-Claws. The appearance and interface are designed to be familiar to new users coming from other popular email clients, as well as experienced users. Almost all commands are accessible with the keyboard.
The software is intended to be light-weight and it has a similar interface to that of Sylpheed’s.
It is also extensible using loadable plugins, which can provide support for additional features, such as other storage formats, feed reader, calendar management, mail filtering, etc.
