Sylpheed is an open-source e-mail client and news client licensed under GNU GPL-2.0-or-later with the library part LibSylph under GNU LGPL-2.1-or-later. 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 it is also usable on Windows. It uses GTK+.[3]
In 2005, Sylpheed was forked to create Sylpheed-Claws, now known as Claws Mail.[4] As of 2020, both projects continue to be developed independently.
Sylpheed is the default mail client in Lubuntu, Damn Small Linux and some flavours of Puppy Linux.[5]
Features[edit]
Spam filtering[edit]
Sylpheed provides support for spam filtering using either bogofilter or bsfilter, at the user's choice. Bsfilter is shipped with the Windows version of Sylpheed.[6]
Plug-ins[edit]
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.[7]
Limitations[edit]
Sylpheed is unable to send HTML mail. This is intentional, since the developers consider HTML mail to be harmful.[6] It is still possible to receive HTML mail using Sylpheed.
Password[edit]
The password is stored in plaintext in the Sylpheed configuration file, which by default is only readable by "owner" and not by "group" nor "other".[8] A feature called "master password" prevents Sylpheed from holding plaintext passwords, but does not protect stored messages from other local users with administrator privilege.[9]
Encryption[edit]
Sylpheed includes natively PGP Sign and PGP Encrypt options in the compose window (which requires however an encryption tool based on PGP already installed on the computer).[10] This function is simple to handle yet not intuitive to set up.[11]
