Claws Mail is a free and open-source, C/GTK-based e-mail client, which is both lightweight and highly configurable.[2][3] Claws Mail runs on both Windows[4] and Unix-like systems such as Linux, BSD, and Solaris. It stores mail in the MH mailbox format. Plugins allow to read HTML mail, but there is none to compose HTML messages.[5]
