Sylpheed is an open-source e-mail client and news client licensed under the GPL. It provides easy configuration and an abundance of features. It stores mail in the MH Message Handling System. Sylpheed runs on Unix-like systems such as Linux or BSD, and Windows. It uses GTK+.
Sylpheed supports the development of plug-ins. As of February 2015, Sylpheed's website notes an attachment-tool plug-in, an automatic mail forwarding plug-in, and a plug-in for determining whether or not attachments are password-protected.
Sylpheed is unable to send HTML mail. This is intentional, since the developers consider HTML mail to be harmful. It is still possible to receive HTML mail using Sylpheed.
