Secure Email List Services (SELS) is an open source
software for creating and developing secure email list services among user
communities. SELS provides signature and encryption capabilities while
ensuring that the List Server does not have access to email plain text. SELS
has been developed with available open-source components and is compatible
with many commonly used email clients.

We are not able to support new lists at this time.
The SELS source code is available from the
Sourceforge project
