Exchange of private information content among a large number of users via E-mail List Services is becoming increasingly common. In this paper we address security requirements in that setting and develop a new protocol, SELS (a Secure E-mail List Service) that provides confidentiality, integrity, and authentication for e-mails exchanged via lists. In addition, SELS also protects against the use of lists for e-mail spamming. We have developed a prototype of SELS in Java, and integrated it with the Eudora e-mail client.
